CROSS-REFERENCES TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Patent Application No. 62/733,905, filed Sep. 20, 2018, entitled “Multifunction Accessory Case,” which is herein incorporated by reference in its entirety and for all purposes. 
    
    
     FIELD 
     The described embodiments relate generally to multifunction charging and storage cases for portable listening devices such as earbuds. 
     BACKGROUND 
     As wearable devices, such as smart watches, achieve greater connectivity and improved capabilities, users are opting to reply primarily on their wearable device for communications and connectivity by leaving their smart phones and/or other mobile devices behind as a matter of convenience. While some modern wearable devices allow for cellular communication, using the microphone and speaker on a wearable device for phone calls can be less than optimum experience. Thus, users often carry wireless headphones, such as earbuds and their accompanying storage cases, with them to listen to music while running, bicycling, or simply carrying out daily errands or activities. Using the paired wireless headphones allows for a more natural user experience for telephone calls from the wearable device. While many users are choosing to operate at times without their mobile devices, some mobile devices can provide additional features, such as a camera, that that are either not implemented on or have limitations in embodiments of wearable devices. For example, digital cameras built into a wearable device might have drawbacks due to space constraints of the wearable device and/or limited degrees of freedom for use because the wearable device can be, for example, attached to a wrist of a user. 
     SUMMARY 
     Embodiments of the disclosure pertain to a multifunction case that can be used to charge and store wireless earbuds or other headphones. Users often use wireless earbuds in conjunction with either a mobile device or a wearable device. Storage cases for wireless earbuds or other headphones can be designed to store and charge the earbuds when not in use. Users often carry the case for the wireless earbuds with them due to the compact size, the protection the case provides for the earbuds while not in use, and the ability to charge the earbuds. According to embodiments of the disclosure, additional features can be incorporated into a charging and storage case for wireless earbuds that supplement the existing features of a wearable device (or other host device) that the earbuds can be paired with. One such feature can be a digital camera.

     As used herein, the term “portable listening device” includes any portable device designed to play sound that can be heard by a user. Headphones are one type of portable listening device, portable speakers are another. The term “headphones” represents a pair of small, portable listening devices that are designed to be worn on or around a user&#39;s head. Headphones can convert an electrical signal to a corresponding sound that can be heard by the user. Headphones include traditional headphones that are worn over a user&#39;s head and include left and right listening devices connected to each other by a headband, headsets (a combination of a headphone and a microphone); and earbuds (very small headphones that are designed to be fitted directly in a user&#39;s ear). Traditional headphones include both over-ear headphones (sometimes referred to as either circumaural or full-size headphones) that have earpads that fully encompass a user&#39;s ears, and on-ear headphones (sometimes referred to as supra-aural headphones) that have earpads that press against a user&#39;s ear instead of surrounding the ear. As used herein, the term “earbuds,” which can also be referred to as earphones or ear-fitting headphones, includes both small headphones that fit within a user&#39;s outer ear facing the ear canal without being inserted into the ear canal, and in-ear headphones, sometimes referred to as canalphones, that are inserted in the ear canal itself. 
       FIG. 1  illustrates a simplified front perspective view of a multifunction accessory case  100  according to some embodiments of the disclosure. Multifunction accessory case  100  includes a housing  105 , also called a body, and a lid  110  that can be pivotably coupled to housing  105  by a hinge  124 . Housing  105  defines an interior space in which a pair of earbuds (not shown) can be stored. 
     In some embodiments, an insert can be fit within the interior space of the housing  105  to define one or more cavities that are sized and shaped to accept the earbuds. An example of such an insert is below with respect to  FIG. 7 . In some embodiments, cavities can be positioned adjacent to each other on opposite sides of a center plane of case  100 . Each cavity can be sized and shaped to match that of its respective earbud. Each cavity can include a stem section and a bud section. Each stem section can be an elongated generally cylindrical cavity that extends from its respective bud section towards a bottom of case  100 . Each bud section can be offset from its respective stem section and open at an upper surface of housing  105 . Embodiments of the disclosure are not limited to any particular shape, configuration or number of cavities and in other embodiments cavities can have different shapes to accommodate different types of earbuds, different configurations and/or can be a single cavity or more than two cavities. 
     Lid  110  can be moved between a closed position in which the lid covers the interior space and an open position (illustrated in  FIG. 1 ) in which an opening  115  of the housing can be exposed to allow a user to place the earbuds within or remove the earbuds from the interior space. Lid  110  can be operable between a closed position where lid  110  can be aligned over one or more cavities fully enclosing pair of earbuds within the housing, and an open position where the lid  110  can be displaced from the housing and cavities such that a user can remove the earbuds from the cavities or replace the earbuds within the cavities. Lid  110  can be pivotably attached to housing  105  and can include a magnetic or mechanical system (not shown in  FIG. 1 ) that provides lid  110  with a bi-stable operation. 
     In some embodiments, case  100  can also include a charging system configured to charge pair of earbuds; one or more magnets configured to orient and retain the pair of earbuds within one or more cavities; and other features that are further described below.

The microphone  140  can receive audio information (e.g., aural instructions) for an intelligent assistant. The intelligent assistant can receive audio commands from a user to perform different functions of the multifunction accessory case  100 . The location of the microphone  140  on the case  100  is exemplary. One or more locations for the microphone  140  can be selected based on ports or gaps between the internal electronic components of the case  100 . Additionally, some embodiments can include multiple microphones for improved performance, to enable noise cancellation and/or to enable other features. 
     In some embodiments, external mounting structures (e.g., protuberances) can be formed on the housing  105  to allow the multifunction accessory case to be affixed to a case, a tripod, a helmet, or similar mounting structure. In some embodiments, external mounting structures on the housing  105  can connect to an external battery that can supplement or recharge the case battery. 
     In some embodiments, the multifunction accessory case  100  can be water resistant. As defined herein, a liquid-tight seal shall mean a seal that conforms to one or more of the following ratings as defined by the International Protection Rating and International Electrochemical Commission (IEC) 60529 that can also be known as the I.P.68 rating. In some embodiments the liquid-tight seal can protect the connector assembly against the harmful ingress of water. 
     The accessory case  100  can also include thermal heat spreaders and/or heat synchs distributed throughout the case  100 . The camera  120  and other circuitry within case  100  can generate heat, especially during camera operation with preview mode. Heat spreaders and/or heat synchs can be embedded or molded into the case  100  or can be separate elements that are thermally coupled to the camera or other heat generating components. The case  100  can be constructed from materials with different thermal characteristics, such as plastic, graphite, or metallic alloys, to help distribute heat from the camera and other internal electronics to external surfaces of the case where heat is more readily dissipated. As one example, in some embodiments the body  105  and/or lid  110  of case  100  can be predominantly made from a polymer-based plastic material doped with a thermally conductive material, such as graphene, to improve heat dissipation 
       FIG. 2  illustrates a simplified rear perspective view of the multifunction accessory case  100  depicted in  FIG. 1  shown without lid  110  for ease of illustration.  FIG. 2  illustrates a second major side of the housing  105  opposite the first major side visible in  FIG. 1  that includes the digital camera lens  125 . As shown in  FIG. 2 , first and second buttons  245  and  250  can be positioned at an exterior surface of the housing  105 . The first and second buttons  245  and  250  can be used to receive input from a user and carry out various functions that can be implemented by case  100 . As an example, the first button  245 , which is shown in  FIG. 2  as being positioned on the rear, major surface of housing  105 , can be used for pairing the earbuds stored within or matched to case  100  with another electronic device (e.g., a wearable device, a smartphone or a tablet). As another example, the second button  250 , which is shown in  FIG. 2  as being positioned on a side surface of housing  105  that extends between the two major sides of the housing, can activate the camera mode of the multifunction accessory case  100  can act as a shutter button for the digital camera  120 . For example, the second button can start, pause, and/or stop video capture from the digital camera  120 . Placing button  250  on the side of housing  105  can facilitate one-handed operation of the digital camera  120  by providing a convenient location to activate the camera shutter when the camera is pointed towards its subject. 
     In some embodiments, multifunction accessory case  100  includes just a single user interface button that can be used to activate all the functions of the first and second buttons  245 ,  250  or different functions. Other embodiments can include voice-activated controls, in addition to or instead of buttons  245 ,  250 , to operate accessory case  100  in camera mode and/or perform other functions for the accessory case. Still other embodiments can activate modes of case  100  by tapping on one or more of the earbuds stored in the case or when the earbuds are worn by a user. For example, when case  100  is in camera mode, tapping on one of the earbuds can activate the shutter for the digital camera in some embodiments. 
     In some embodiments various case  100  can include various features designed to prevent a user from inadvertently activating the camera  120 . For example, in some embodiments shutter button  250  only operates after a two-step process where the button is first held down for an extended time period (e.g., one second) to activate a camera mode of the case. Once case  100  is in camera mode, a single click of button  250  can snap a picture from camera  120  while a double click can take a video and a second double click can stop the video. To end camera mode, shutter button  250  can be held down again for an extended period (e.g., one second). Some embodiments of case  100  can also slightly recess the second button  250  within the housing  105  to avoid inadvertent activation when, for example, a user picks up the charging case and inadvertently touches the area of button  250 . 
     In some embodiments the multifunction accessory case  100  can be paired with another electronic device (e.g., a smartphone, a tablet, or a wearable device) that can be referred to as a host device. The digital camera  120  can be operated through an application executed on the host device. For example, the shutter can be operated through one or more controls operated through the touchscreen or pushbuttons of the host device. In some embodiments, a display of the wearable device can act as a viewfinder for the digital camera  120 , shown in  FIG. 1 , on the multifunction accessory case  100 . In some embodiments, a display on the host device can be a touchscreen display that can be used to activate one or more features of the multifunction accessory case  100  (e.g., a camera mode, feature, or shutter button 
       FIG. 3A  illustrates a simplified front perspective view of a multifunction accessory case  300  according to additional embodiments of the invention. Case  300  can be similar to case  100  and include many of the same features as case  100 . For example, case  300  can include an opening  315  to receive a pair of earbuds (or to receive an insert, such as insert  700  shown in  FIG. 7 , the receives the pair of earbuds), a digital camera  320 , a strobe  330 , a speaker  335  and a microphone  340  all of which can be similar to the corresponding components described above with respect to  FIGS. 1 and 2 . 
     As shown in  FIG. 3A , however, case  300  includes a lid  310  that is connected to its body  305  by a hinge  324  located on a minor side  304  of the housing  305  that extends between first and second major sides  302  and  306  (shown in  FIG. 3B ), respectively. Thus, lid  310  opens by rotating about the hinge  324  on the shorter side of the housing  305  as opposed to the longer side. Additionally, hinge  324  can provide sufficient friction in the movement of lid  310  such that the lid  310  can be partially opened (i.e., set between the fully open and fully closed positions) and stay in the partially opened position even when the distal end  312  of lid  310  (opposite the end at hinge  324 ) is placed against a surface, such as a table top, to support body  305 . This allows the lid  310  can be used as a kickstand for the multifunction accessory case  300  such that case  300  can be positioned at various angles for capturing photos, videos, or video conferencing applications. Additionally, in some embodiments the camera  320  can be used in a timer mode for self-portraits and the kickstand operation provides a convenient mechanism for the case to be supported at a desired angle for the picture or portrait. 
     In some embodiments lid  310  can be moved between the fully opened and fully closed positions into multiple discrete stops (e.g., 4, 8, 10 or more different, discrete positions or stops in various embodiments). In other embodiments, hinge  324  provides an infinite number of adjustments between the fully opened and fully closed positions similar to a hinge used in various laptop computers between the keyboard portion and the display portion 
       FIG. 3B  illustrates a simplified rear perspective view of multifunction accessory case  300  shown in  FIG. 3A  without lid  310  for ease of illustration. In  FIG. 3B , major side  306  of the housing  305  is shown as including a first button  345  and minor side  308  is shown as including a second button  350 . First and second buttons  345 ,  350  can be similar to or identical to buttons  245  and  250 , respectively, described above with respect to  FIG. 2 . 
       FIG. 4  illustrates a simplified front perspective view of a multifunction accessory case  400  according to another embodiment of the invention. Case  400  can be similar to case  100  and include many of the same features as case  100 . For example, case  400  can include an opening  415  to receive a pair of earbuds (or to receive an insert, such as insert  700  shown in  FIG. 7 , the receives the pair of earbuds), a digital camera  420 , a strobe  430 , a speaker  435  and a microphone  440  all of which can be similar to the corresponding components described above with respect to  FIGS. 1 and 2  except that the digital camera and strobe can be positioned in the lid  410  of case  400  instead of within its body. 
     Case  400  can also include one or more sensors (not shown) that detect when lid  410  is opened. In some embodiments the one or more sensors can be magnetic sensors, such as a hall effect sensor. For example, lid  410  may include a magnet that generates a magnetic field. The hall effect sensor can be placed in the body  405  of case  400  and detects whether the lid is opened or closed based on whether or not it can detect a magnetic field from the lid magnet. In various embodiments, the one or more sensors can cause case  400  to turn on camera mode (in which button  450  acts as a shutter button that can take pictures from camera  420 ) when the sensors detect that lid  410  has been opened. In other embodiments a two-step process can be required to initiate camera mode, such as opening the lid  410  followed by depressing button  450 . 
       FIG. 5  depicts a block diagram of a digital camera feature for a multifunction accessory case including a digital camera  500  in accordance with the present disclosure. The digital camera  500  can be a battery operated device, small enough to fit within the confines of a multifunction accessory case  100  (shown in  FIG. 1 ) for capturing and reviewing images. The digital camera  500  produces digital assets that can be stored as digital asset files using a memory  530 . 
     Camera  500  can include an image sensor such as a complementary metal-oxide-semiconductor (CMOS) sensor and optical components (e.g., lenses) arranged to focus an image onto the image sensor, along with control logic operable to use the imaging components to capture and store still and/or video images. Images can be stored in memory  530  and/or transmitted by the multifunction accessory case  100  to other devices for storage through the wired/wireless interface  538 . In some embodiments, the images/video can be transferred from the case  100  when connected via a Depending on implementation, the optical components can provide fixed focal distance or variable focal distance; in the latter case, autofocus can be provided. In some embodiments, camera  500  can be disposed in face of a housing for a multifunction accessory case  100 . Zero, one, or more cameras can be provided, depending on implementation. The digital camera  500  can be configured to be in a constant ready mode which allows for quicker capture of digital assets. However, the constant ready mode can have a drawback of higher battery demand. The digital camera  500  can alternatively be initiated by turning on the feature through a user controls  534 , through a paired wearable device, or mobile device, through a voice command to a virtual assistant, or through a first button  235  or a second button  240 , shown in  FIG. 2 , on the housing of the case  100 . 
     In some embodiments, the digital camera  500  captures both motion video images and still images. The digital camera  500  can include a lens  504  having an adjustable aperture and adjustable shutter. In some embodiments one or more filters  506  can cover at least in part the lens  504  of the camera. The lens  504  can be a zoom lens and can be controlled by zoom and focus motor drivers. The lens  504  focuses light from a scene (not shown) onto an image sensor  514 , for example, a single-chip color charged-coupled device (CCD) or CMOS image sensor. The lens  504  can be one typical for an optical system for forming an image of the scene on the image sensor  514 . In other embodiments, the optical system may use a fixed focal length lens  504  with either variable or fixed focus. 
     The output of the image sensor  514  can be converted to digital form by Analog Signal Processor (ASP) and Analog-to-Digital (A/D) converter, and stored in memory  530 . The digital asset stored in memory  530  can be subsequently manipulated by a processor  520 , using embedded software programs (e.g., firmware) stored in memory  530 . In such embodiments, the memory  530  can also be used to store image sensor calibration data, user setting selections, and other data which can be preserved when the camera is turned off. 
     It can be understood that the functions of processor  520  can be provided using a single programmable processor or by using multiple programmable processors, including one or more digital signal processor (DSP) devices. Alternatively, the processor  520  can be provided by custom circuitry (e.g., by one or more custom integrated circuits (ICs) designed specifically for use in digital cameras), or by a combination of programmable processor(s) and custom circuits. It can be understood that connectors between the processor  520  from some or all of the various components shown in  FIG. 5  can be made using a common data bus. For example, in some embodiments the connection between the processor  520 , the memory  530 , the wired/wireless interface  538  can be made using a common data bus. 
     The processed images are then stored using the memory  530 . It can be understood that the image memory  530  can be multiple different memory chips or elements each of which can be any form of memory known to those skilled in the art for such purposes including, but not limited to, a removable Flash memory card, internal Flash memory chips, magnetic memory, or optical memory. In some embodiments, the memory  530  can include both internal Flash memory chips and a standard interface to a removable Flash memory card, such as a Secure Digital (SD) card. Alternatively, a different memory card format can be used, such as a micro SD card, Compact Flash (CF) card, MultiMedia Card (MMC), xD card or a Memory Stick. 
     The image sensor  514  can have, for example, 12.4 megapixels (4088×3040 pixels) in order to provide a still image file of approximately 4000×3000 pixels. To provide a color image, the image sensor can be generally overlaid with a color filter array, which provides an image sensor having an array of pixels that include different colored pixels. The different color pixels can be arranged in many different patterns. 
     It can be understood that the image sensor  514  can include separately fabricated integrated circuits, or can be fabricated as a single integrated circuit as can be commonly done with CMOS image sensors. In some embodiments, this single integrated circuit can perform some of the other functions shown in  FIG. 5 , including some of the functions provided by processor  520 . 
     The image sensor  514  can be effective when actuated in a first mode by timing generator  512  for providing a motion sequence of lower resolution sensor image data, which can be used when capturing video images and also when previewing a still image to be captured, in order to compose the image. This preview mode sensor image data can be provided as high-definition (HD) resolution image data, for example, with 1280×720 pixels, or as VGA resolution image data, for example, with 640×480 pixels, or using other resolutions which have fewer columns and rows of data, compared to the resolution of the image sensor. The image sensor  514  can be actuated in a second mode for providing high resolution still image data. 
     The zoom and focus motor drivers are commanded by control signals supplied by the processor  520 , to provide the appropriate focal length setting and to focus the scene onto the image sensor  514 . The exposure level of the image sensor  514  can be adjusted by controlling the f/number and exposure time of the adjustable aperture and adjustable shutter, the exposure period of the image sensor  514  via a timing generator, and the gain (i.e., International Organization for Standardization (ISO) speed) setting of an analog signal processor or analog to digital converter. The processor  520  can also control a strobe or flash  502  which can illuminate the scene. The strobe or flash  502  can include one or more light emitting diodes (LEDs). 
     The lens  504  of the digital camera  500  can be focused in the first mode by using “through-the-lens” autofocus. This can be accomplished by using the zoom and focus motor drivers to adjust the focus position of the lens  504  to a number of positions ranging between a near focus position to an infinity focus position, while the processor  520  determines the closest focus position which provides a peak sharpness value for a central portion of the image captured by the image sensor  514 . The focus distance which corresponds to the closest focus position can then be utilized for several purposes, such as automatically setting an appropriate scene mode, and can be stored as metadata in the image file, along with other lens and camera settings. 
     The processor  520  can generate menus and low resolution color images that are temporarily stored in memory  530  and are displayed on a display screen  532 . In some embodiments, display screen  532  is part of a paired device, such as a wearable device or mobile device. In other embodiments, display screen  532  can be incorporated on an accessory case, such as case  100  shown in  FIG. 1 . The display screen  532  can be a color liquid crystal display (LCD), although other types of displays, such as organic light emitting diode (OLED) displays, can be used. In preview mode, or video mode, the digital image data from memory  530  can be manipulated by processor  520  to form a series of motion preview images that are displayed, typically as color images, on the display screen  532 . In review mode, the images displayed on the display screen  532  are produced using the image data from the digital image files stored in image memory  530 . 
     The graphical user interface displayed on the display screen  532  can be controlled in response to user input provided by user controls  534 , which can include controls on one or both of a wearable device, such as a smart watch, and a case for an accessory, such as multifunction case  100 . The user controls  534  are used to select various camera modes, such as video capture mode, still capture mode, and review mode, and to initiate capture of still images and recording of motion images. In some embodiments, the first mode described above (i.e., still preview mode) can be initiated when the user partially depresses a shutter button, which can be one of the user controls  534 , and the second mode (i.e., still image capture mode) can be initiated when the user fully depresses the shutter button. The user controls  534  are also used to turn on the digital camera  500 , control the lens  504 , and initiate the picture taking process. User controls  534  typically include some combination of buttons, rocker switches, joysticks, or rotary dials. In some embodiments, some of the user controls  534  are provided by using a touch screen overlay on the display screen  532 . In other embodiments, additional status displays or images displays can be used. In some embodiments, the user controls can be provided through a paired device such a wearable device or mobile device. 
     The camera modes that can be selected using the user controls  534  include a “timer” mode. When the “timer” mode can be selected, a short delay (e.g., 10 seconds) occurs after the user fully presses the shutter button, before the processor  520  initiates the capture of a still image. In some embodiments equipped with a speaker, the timer can be audibly announced. 
     An audio codec  522  connected to the processor  520  receives an audio signal from a microphone  524  and provides an audio signal to a speaker  526 . These components can be used to record and playback an audio track, along with a video sequence or still image. 
     In some embodiments, the speaker  526  can be used as part of the user interface, for example to provide various audible signals which indicate that a user control has been depressed, or that a particular mode has been selected. In some embodiments, the microphone  524 , the audio codec  522 , and the processor  520  can be used to provide voice recognition, so that the user can provide a user input to the processor  520  by using voice commands, rather than user controls  534 . The speaker  526  can also be used to inform the user of an incoming phone call. This can be done using a standard ring tone stored in firmware memory  528 , or by using a custom ring-tone downloaded from a wireless network  558  and stored in the image memory  530 . 
     The processor  520  also provides additional processing of the image data from the image sensor  514 , in order to produce rendered standard Red Green Blue (sRGB) image data which can be compressed and stored within a “finished” image file, such as a well-known exchangeable image file (Exif-JPEG) image file, in the memory  530 . 
     The digital camera  500  can be connected via the wired or wireless interface  538  to an interface/recharger, which can be connected to a host device, which can be a desktop computer or portable computer located in a home or office. The wired/wireless interface  538  can conform to known interface specifications and utilize a variety of different protocols. For example, the wireless protocols can include Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE), LTE, Zi-Wave, Zigbee, WirelessHD, WiGig, Z-Wave, and Ultra-Wide Band (UWB). Wired protocols can include, for example, for example, USB 2.0, USB 3.0, USB type C, Apple Lightning, Thunderbolt, Firewire, or other suitable wired protocols. 
     The digital camera  500  can include a wireless transceiver, which interfaces over a radio frequency band with the wireless network. The wireless transceiver can use various wireless interface protocols, such as the well-known Bluetooth wireless interface or the well-known 802.11 wireless interface. The host device can share images via the Internet to sharing destinations, such as an E-mail address, a picture sharing website, a social networking website, a digital picture frame, a multimedia message to a cell-phone or a printing service. Other devices (not shown) can access the images stored on the host device, or stored at one of the sharing destinations. The sharing destinations can be specified by the user using the user controls  534 . Typically, the user can be allowed to designate one or more sharing destination for each digital image captured by the digital camera  500  and stored in the image memory  530 . 
     In alternative embodiments, the wireless transceiver communicates over a radio frequency (e.g., wireless) link with a mobile phone network (not shown), such as: Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), cdmaOne, CDMA2000, Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/TDMA), and Integrated Digital Enhanced Network (iDEN), Long-Term Evolution (LTE), 3 AGSM, 4G, or 5G network, which connects with the Internet in order to upload digital image files from the digital camera  500 . These digital image files can be provided to the host device or the sharing destinations. 
       FIG. 6  is a top plan view of an accessory case  600  that can be representative of one of the multifunction accessory cases discussed herein, such as case  100  or case  300 .  FIG. 6  illustrates an exemplary orientation of a pair of earbuds  602 ,  604 , including a non-occluding left earbud  602  and a non-occluding right earbud  604 , positioned within a housing  605  of the case. Generally, non-occluding earbuds are designed not to form an airtight seal between the ear (or ear canal) and the outer surface of the earbud. By way of contrast, occluding earbuds are generally designed to fit inside of the user&#39;s ear canal and form a substantially airtight seal. Each earbud  602 ,  604  can include an external earbud housing  606  having an ear portion coupled to a stem portion. Earbud housing  606  can have an asymmetric shape amenable to in-the-ear retention, but does not form an airtight seal with the user&#39;s ear or ear canal. The absence of an airtight seal can benefit from volumes within the earbud being specifically tuned (e.g., by specifically shaping the volumes and/or adding material to the volumes) to achieve a desired frequency response. The ear portion of the earbuds  602 ,  604  can include a directional sound port  608  offset with respect to a center axis of each ear bud  602 ,  604 . Directional sound port  608  can be designed to direct sound waves from an internal driver directly into a user&#39;s ear canal. 
     In addition, secondary apertures in the earbud can be employed in housing  606  to achieve desired sound performance. For example, one or more secondary apertures can serve as a controlled leak port to expose an acoustic pressure within the earbud to the external, surrounding environment. In this aspect, the secondary apertures can be calibrated to modify an acoustic response of the earbud. In this embodiment earbuds  602 ,  604  each include a front leak port (not shown in  FIG. 6 ) and a multiport  610  formed in ear portion. Multiport  610  can include both a rear vent  612  and a bass port  614 . In addition, earbuds according to embodiments of this disclosure can be constructed to have a seamless finish even though two or more parts are joined together to form part of the earbud. 
     Ear portion of earbuds  602 ,  604  can also include one or more “in the ear” sensors to assist each earbud  602 ,  604  in determining whether or not the earbud is in a user&#39;s ear. In one embodiment an optical tragus sensor can be configured to sense the presence or absence of a user&#39;s tragus, and an optical concha sensor can be configured to sense the presence or absence of a user&#39;s concha. Tragus and concha sensors, respectively, can use any type of optical sensor including, but not limited to an LED or vertical cavity surface emitting laser (VCSEL) device. Further embodiments can include one or more capacitive sensors and/or accelerometers to detect the presence of a user&#39;s ear and/or earbud orientation, as described in more detail below. In the ear detection can be useful for features such as, but not limited to, determining which earbud  602 ,  604  to use as a microphone when a user desires to accept an audio or video call and when a user stops using one earbud and starts using the other earbud. 
     In various embodiments, a distal end of stem portion of each earbud  602 ,  604  can include one or more electrical contacts that can be positioned and formed to make electrical contact with contacts within the charging case  600 . In one particular embodiment, each earbud  602 , 604  can include first and second electrical contacts spaced apart from each other in an oppositional and symmetrical relationship, such as partially annular contacts. Each of the first and second contacts can include an outer perimeter that can be flush with an exterior surface of the stem portion and include an arcuate or other curved surface that creates a strong wiping action during a contact mating event. The contacts can be used to transfer power from case  600  to recharge an internal battery within each earbud  602 ,  604  and in some instances can also be used to transfer data to and from each earbud. In other embodiments wireless charging components can be included within each earbud enabling the earbuds to be wirelessly charged by case  600 . The distal end of each earbud can also include a bottom microphone port that works in conjunction with a top microphone port to receive a user&#39;s voice and/or perform noise cancellation. 
       FIG. 7  is an isometric view of an insert  700  according to some embodiments of the disclosure that can be included within an earbud charging and storage case according to some embodiments of the disclosure. For example, insert  700  can be inserted into case  100  through opening  115  such that a top surface  705  of the insert is flush with (or nearly flush with) the upper edge of housing  105 . When included in a case, such as case  100 , insert  700  can store a pair of earbuds in the orientation depicted in  FIG. 6 . 
     As shown in  FIG. 7 , insert  700  includes first and second shells  702 ,  704  that define receiving cavities for a pair of earbuds retaining and guiding a stem portion of each earbud into the multifunction accessory case  100  (see  FIG. 1 ). The location and orientation of the first and second shells  702 ,  704  can provide a natural orientation for insertion of the earbuds into the ear cavity. The receiving cavity  706  in each of the shells  702 .  704  can include an elongated tube portion that opens to a larger earbud receiving opening. The elongated tube portion can be sized and shaped to accommodate the stem section of an earbud and the larger earbud receiving opening can be sized and shaped to partially or fully accommodate the ear interface portion (i.e., the portion of the earbud that fits within a user&#39;s ear). 
     In some embodiments shells  702 ,  704  can be separate components joined together by the contact  708  carrier while in other embodiments shells  702 ,  704  can be a single component that can be formed, for example, in a molding process, a 3D printing process or with a milling process. Contact carrier  708  holds first and second earbud contacts, that can interface with a first earbud, and also holds third and fourth earbud contacts that can interface with a second earbud. A collar  710  can be bonded to a top surface of contact carrier  708 . In some embodiments collar  710  can have a removable tie bar (not shown in  FIG. 7 ) that holds the multiple pieces of the collar together during assembly and that can then be removed after assembly such that the tie bar is not included within a finished earbud case. 
     Distal ends  712 ,  714  of first and second shells  702 ,  704 , respectively, can be narrower than the elongated tube portion of shell and each distal end  712 ,  714  can be fit within and bonded to collar  710  forming a completed shell and insert assembly illustrated in  FIG. 7 . In the completed assembly, each earbud case contact fits within a respective contact opening of shell and each earbud case contact fits within a respective contact opening of shell. Each contact opening enables its respective contact to extend into the earbud receiving cavity within its respective shell  702 ,  704  to make electrical contact with an earbud contact during a mating event. 
     In various embodiments, a digital camera and a lens  720  can be installed between the first and second shells  702 ,  704 . A compartment  722  behind the lens  720  can contain digital processing circuitry and a memory for the digital camera. In some embodiments, the lens  720  can be removed and exchanged for one or more different lens types (e.g., zoom, wide angle). In some embodiments, the lens  720  can implement an ultra-wide angle camera lens having a 120 degree field of view. 
     In some embodiments insert  700  can be made primarily from a polymer or other suitable plastic material. And, in some embodiments, insert  700  can include the one or more heat spreaders or heat synchs discussed above. For example, heat spreaders can be molded into or otherwise incorporated into the bottom portion of insert  700  such that the heat spreaders are thermally coupled to the camera and its components within compartment  722  in order to transfer heat generated by the camera and its components to an exterior surface of the charging case in which insert  700  is included. Towards this end, in some embodiments, the charging case can include one or more portions of its housing that are made from a thermally conductive material in regions adjacent to compartment  722 . These portions can be thermally coupled to the heat spreaders to enable heat from the camera to be better dissipated to the external environment. 
     In some embodiments, the insert  700  can include a camera that can be water resistant. In some embodiments, the lens  720  can implement a one or more filter  506  (e.g., a red filter) for improving underwater photography in which red light experiences higher absorption and scattering underwater. The absorption of light in water depends on the wavelength, with light in the red and violet ends of the spectrum being strongly attenuated while blue-green region of the visible spectrum has minimum attenuation. The earbud receptacle connector  700  can include an underwater pressure sensor that automatically adjusts the red gain as the water pressure increases signifying operations at increasing underwater depths. 
       FIG. 8  is a simplified rear perspective view of a multifunction accessory case  800  (shown without its lid) according to some embodiments of the disclosure. Case  800  can includes many or all of the same components as described above with respect to case  100 . Thus, case  800  can include an opening  815  to receive a pair of earbuds, a digital camera (not shown), a strobe (not shown), a speaker (not shown) and microphone (not shown)  330  all of which can be similar to the corresponding components described above with respect to  FIGS. 1 and 2 .

     Case  800  can also include a display  860  positioned at an exterior surface of the case, such as on the rear of its housing  805 . Display  860  can be a liquid crystal display (LCD), organic light emitting diode (OLED), active-matrix organic light-emitting diode (AMOLED), Super AMOLED, thin film transistor (TFT), in-plane switching (IPS), or thin film transistor—liquid crystal display (TFT-LCD) that typically can be found a computing device. In some embodiments, the display  860  can be a touchscreen display. In embodiments where case  800  includes a camera, display  860  can operate as a view finder for the camera displaying to a user the area that a camera within case  800  can capture. 
     In embodiments with or without a camera, display  800  can display visual output via a Graphics User Interface (GUI) to the user. The visual output can include text, graphics, video, and any combination thereof. Some or all of the visual output can correspond to user-interface objects. A touch-sensitive display can also accept input from the user based on haptic and/or tactile contact. In some embodiments, a touch-sensitive display forms a touch-sensitive surface that accepts user input. The touch-sensitive display/surface (along with any associated modules and/or sets of instructions in the computer-readable medium) detects contact (and any movement or release of the contact) on the touch-sensitive display and converts the detected contact into interaction with user-interface objects, such as one or more soft keys, that can be displayed on the touch screen when the contact occurs. In some embodiments, a point of contact between the touch-sensitive display and the user corresponds to one or more digits of the user. The user can make contact with the touch-sensitive display using any suitable object or appendage, such as a stylus, pen, finger, and so forth. A touch-sensitive display surface can detect contact and any movement or release thereof using any suitable touch sensitivity technologies, including capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch-sensitive display. 
     In some embodiments, the multifunction accessory case  800  can have one or more vias or connection points on the housing  805  that can connect to a detachable display  860  allowing the display to be removably coupled to the case  800 . 
       FIG. 9  is a simplified block diagram depicting various components of a power charging system  900  according to some embodiments of the disclosure. Charging system  900  can include a power source  912 , an earbud case  920 , and a pair of earbuds  940   a ,  940   b . Earbud case  920  can be any of the earbud cases, such as earbud case  100 ,  300 , etc., disclosed herein. 
     In some embodiments, a wireless charging pad (not shown) can include multiple wireless power transmitters (not shown) beneath the surface of the charging area. The multiple wireless power transmitters enable charging pad to simultaneously wireless charge more electronic devices and enable the devices being charged to be randomly placed within a charging area of the charging pad defined by the placement of the wireless power transmitters. 
     Earbud case  920  can include one or more wireless power receiving elements  922 , a wired power adapter  924 , switching circuitry  926 , a battery  928 , charging circuitry  930 , and an earbud interface  932 . Battery  928  can be a rechargeable battery that provides power for circuitry associated with earbud case  920 . Wireless power receiving elements  922  can wirelessly receive power from the power source  912  within charging pad. The received power can be provided to charging circuitry  930  to charge the rechargeable battery  928 . Charging circuitry can take the voltage received from receiving elements  922  and step the voltage down or up as appropriate to a voltage level that can be best suited for charging battery  928 . Alternatively, a wired power adapter  924  can receive electrical power from the power source  912 . 
     When the earbuds are properly positioned and stored within case  920 , battery  928  can also be used to charge one or both of earbud rechargeable batteries  944   a ,  944   b  within the respective earbuds  940   a ,  940   b  through a connection between earbud interface  932  within the earbud case and the case interfaces  942   a ,  942   b  within each earbud. In this manner, battery  928  enables the earbuds to be charged even though case  920  is not electrically coupled to power source  910  or to another power source. Thus, case  920  can be used to charge pair of earbuds  940   a ,  940   b  while the case can be, for example, in a user&#39;s pocket as long as case battery  928  has sufficient charge. 
     Additionally, earbud case  920  can recharge batteries  944   a ,  944   b  within each of earbuds  940   a ,  940   b  when the earbuds are properly stored in case  920  from power stored within battery  928  even when the case is not receiving power from power source  912 . 
     In some embodiments, the camera  936  can be powered from the battery  928 . In some embodiments the memory can also be powered by the battery  928 . In some embodiments, the camera  936 , can also use the power from either or both earbud battery  944   a  and  944   b  for electrical power. In some embodiments, the electrical power for the camera  936  can be supplied via inductive charging or an external battery source. In some embodiments, the case  920  can be powered through an external power source connector  924   
     In some embodiments, the housing of charging case  920  can incorporate one or more solar cells to recharged at least in part the case battery  928 . In some embodiments, the solar cells can be foldable and expanded when the case battery  928  is being recharged. 
     In some embodiments, the housing  905  can incorporate a kinetic recharging system. In some embodiments, the kinetic charging system can move a physical magnetic inside an electrical wiring coil, generating an electrical current for recharging the case battery  928 . In some embodiments, the kinetic recharging system is powered from the natural motion of a user&#39;s body while carrying the case  920 . In some embodiments, the kinetic recharging system can be activated by a user shaking the case  920 . 
       FIG. 10  illustrates a wireless pairing system  1000  according to some embodiments of the disclosure. System  1000  includes a multifunction accessory case  1005 , a pair of wireless headphones (e.g., a pair of wireless earbuds), and one or more host devices  1030 ,  1040  (either of which can be, for example, a computer, a smartphone, a tablet computer, a smart watch, or the like). Multifunction accessory case  1005  can be representative of one of the accessory cases disclosed herein, such as case  100  discussed above. The multifunction accessory case  1005  can pair with a wearable device  1015 . The pairing sequence can be initiated by the case  1005  by one or more user-initiated events. In a non-limiting examine opening the case lid  1020  or depressing an input button  1025  can initiate the pairing sequence. In other embodiments, the case  1005  can include a wireless radio that receives pairing instructions from a wearable device  1015 . Upon receiving the pairing instruction, the case can initiate a pairing sequence to a wearable device  1015  via a wireless communication protocol (e.g., via Bluetooth®) that supports bidirectional data transfer. The wearable device  1015  can also be paired with a host device  1030  (e.g., a smartphone or tablet). 
     By pairing with the wearable device  1015 , the multifunction accessory case  1005  can enhance the features resident on the wearable device  1015 . For example, the digital camera  1035  on the multifunction accessory case  1005  can provide a larger lens than would normally be incorporated in the wearable device  1015 . As a paired device, the face  1040  of the wearable device  1015  can be used as a digital viewfinder for the digital camera of the multifunction accessory case  1005 . Commands entered via the touchscreen display of the wearable device  1005  (or by voice control) can be wirelessly communicated to the case  1005 . As the case  1005  would not normally be strapped to a user&#39;s wrist, the camera incorporated in the case  1005  can be more adaptable for capturing digital assets. 
     Through the pairing process, the multifunction accessory case  1005  can utilize the communication features resident on the wearable device  1015 . In various embodiments the wearable device incorporates multi-communications channels (e.g., cellular, Wi-Fi, or Bluetooth) for the sending or receiving data and application data. A paired multifunction accessory case  1005  can now utilize the communication channels of the wearable device  1005  for sending and receiving data over various paths (e.g., cellular). This can allow sensor data collected on the case  1005  to be communicated to the wearable device  1015  and transmitted to one or more network locations. 
     In various embodiments, accessories incorporated as part of multifunction accessory case  1005  can provide additional capabilities. For example, the camera, speaker, and microphone incorporated on the multifunction accessory case  1005  can enable a user to conduct audio or video conferencing on the case using the cellular connection of the host device  1030  or the wearable device  1015 . The display screen on the case  1005  can display digital images, video, and messages, acting as a secondary display, thereby freeing up the display on the host device  1030  or wearable device  1015 . The multifunction accessory case  1005  can also provide additional memory storage capabilities for the storage of music, digital assets (e.g. photos, and videos) in circumstances when the host device  1030  or wearable device  1015  has limited storage available. 
       FIG. 11  illustrates a wireless pairing system  1100  according to an embodiment of the present disclosure that includes a multifunction accessory case  1005 , headphones  1010 , and host device  1030  shown in  FIG. 10 . While  FIG. 11  illustrates simplified block diagrams of each of a multifunction accessory case  1005 , wireless headphones  1010 , and host device  1030 , it can be understood each of the illustrated devices can include functions and features in addition to those illustrated in  FIG. 11 . For example, while not shown in  FIG. 11 , each of multifunction accessory case  1000 , wireless headphones  1010  and host device  1030  can include a battery, such as a rechargeable battery, that provides power to the various components of each device. 
     In some embodiments, host device  1030  can be a wearable device such as a smartwatch Host device  1030  includes a processor  1120 , a memory  1125 , a user interface  1130 , a first wireless transceiver  1135  (e.g., a Bluetooth transceiver), a second wireless transceiver  1140  (e.g., a cellular transceiver) and a wired input/output  1145 . Processor  1120 , which can be implemented as one or more integrated circuits, can control the operation of host device  830 . For example, in response to user input signals provided by a user through user interface  1130 , processor  1120  can initiate programs to search, list or play media assets stored in memory  1125 . In communication with cellular transceiver  1140 , processor  1120  can control placing and receiving of telephone calls. Second transceiver  1140  can also be used to communicate data with a network, including network storage  1115 . First wireless transceiver  1135  can be used to support short range wireless communication (e.g., Bluetooth communication) between host device  1030  and various accessory devices, including a multifunction accessory case  1005 . Memory  1125  can store any information, including Bluetooth pairing information as described in more detail below. Wired input/output  1145  can be any wired connection, such as a USB protocol or a proprietary protocol, such as that used by the Apple Lightning™ connector. 
     As the wearable device has many comparable communication features of a smartphone to include but not limited to cellular voice and data, Bluetooth, and Wi-Fi, a user can use the a wearable device in combination with a multifunction accessory case  1005  in lieu of carrying the smartphone. In some embodiments, the multifunction accessory case  1005  can pair with the host device  1030 . The multifunction accessory case  1005  can includes a processor  1170 , a wired input/output  1175 , and a user input device  1180 , a memory  1185 , and a wireless transceiver  1190 . 
     Processor  1170 , which can be implemented as one or more integrated circuits, can control the operation of multifunction accessory case  1005  by executing computer instructions stored in a computer-readable memory or medium, such as memory  1185 . For example, instructions stored within memory  1185  can cause processor  1170  to, in response to user input signals provided by user input device  1180 , send an instruction to headphones  1010  (e.g., via wired input/output interface  1175  or by a wireless channel between multifunction accessory case  1005  and wireless headphones  810 ) to enter a pairing sequence with a host device. Wired input/output  1175  can be any wired connection between multifunction accessory case  1005  and wireless headphones  810  including a proprietary interconnection. In one example wired input/output  1175  can be a portion of an electrical between pair of earbuds and case. Wired input/output  1175  can be used for charging and/or data. In various embodiments wired input/output  1175  can be used to transmit a signal to headphones  810  to initiate a pairing sequence, as described in more detail below. The processor  1170  can be used to control a digital camera, a strobe, a microphone, and a speaker that can be incorporated in the multifunction accessory case  800 . 
     User input device  1180  can be any device operable by a user. In one embodiment user input device  1180  can be a lid sensor such as lid sensor that detects an opening or a closing of a lid of multifunction accessory case  1005 . In one example an opening event can be detected and processor  1170  sends a signal through wired input/output  1175  of multifunction accessory case to wired input/output  1155  of headphones to processor  1150  of headphones  1010  to initiate a pairing sequence and/or to turn on Bluetooth transceiver  1165 . In another example, wireless headphones  1010  have never been paired before and headphones  1010  enter a pairing sequence. In a further example headphones  1010  have been paired before and headphones  1010  activate Bluetooth transceiver  1165  but do not initiate a pairing sequence. In another example, the multifunction accessory device  1005  can enter a pairing sequence with the host device  1030 . In one embodiment multifunction accessory case  1005  may include one or more indicator lights to notify a user that it has sent a pairing signal to either the host device  1030  or the headphones  1010 . In one embodiment, the multifunction accessory case  1005  may also be equipped with a wireless transceiver  1190  (e.g., a Bluetooth transceiver) that can wirelessly communicate with wireless transceiver  1135  of the host device  1030  of the wireless transceiver  1165  of the wireless headphones  810 . 
     Wireless headphones  1010  can be traditional headphones that are worn over a user&#39;s head, headsets (a combination of a headphone and a microphone), earbuds (very small headphones that are designed to be fitted directly in a user&#39;s ear) or any other portable listening device. In some embodiments wireless headphones  1010  include a processor  1150 , a wired input/output  1155 , a memory  1160  and a wireless transceiver  1165  (e.g., a Bluetooth transceiver). 
     Processor  1150 , which can be implemented as one or more integrated circuits, can control the operation of headphones  1010 . Wired input/output  1155  can be any wired connection between multifunction accessory case  1005  and wireless headphones  1010  including a proprietary interconnection. In one example wired input/output  1155  can be an electrical connector that provides a direct electrical connection between wireless headphones  1010  and multifunction accessory case  1005  when the headphones are mated with the multifunction accessory case  1005  (e.g., stored in a case). Wired input/output  1155  can be used for charging wireless headphones  1010  and/or communicating data with multifunction accessory case  1005 . In one example, wired input/output  1155  of headphones  1010  can be used to receive a signal from wired input/output  1175  of multifunction accessory case  1005  to initiate a pairing sequence of the headphones, as described in more detail below. 
     Wireless transceiver  1165  can be used to support short range wireless communication (e.g., Bluetooth communication) between headphones  1010  and various host devices, including host device  1030 . In one embodiment, multifunction accessory case  1005  may also be equipped with a wireless transceiver (not shown; e.g., a Bluetooth transceiver) that can wirelessly communicate with wireless transceiver  1165 . Wireless transceiver  1165  enables headphones  1010  to communicate wirelessly with host device  1030  once a channel for wireless communication has been established between the two. For example, headphones  1010  and host device  1030  may each be provided with Bluetooth® technology, including appropriate short-range transceiver units. In some embodiments, it may be possible to establish a Bluetooth® pairing between host device  1030  and headphones  1010  using conventional techniques, such as manual entry of a passcode (or PIN code) associated with headphones  1010  into host device  1030 . In other embodiments, Bluetooth® pairings can be established automatically as described below. 
     Memory  1160  can store firmware for operating headphones  1010  as well as data for coupling with other wireless ear buds and for pairing headphones  1010  with companion host devices. For example, memory  1160  can store a connection history for companion host devices such as host device  1030 , with which headphones  1010  have previously paired. The connection history can include data for automatically pairing headphones  1010  with the companion host device without having to configure a connection between the headphones and the companion host device (e.g., enter a password, exchange shared secrets, etc.). For example, the connection history can include one or more link keys for connecting to a wireless network (e.g., Bluetooth link keys). Memory  1160  can also store a MAC address that uniquely identifies headphones  1010  as well as store a paired partner MAC address of another headphone that has previously coupled with the wireless ear bud. For example, in one embodiment headphones  1010  are wireless earbuds and memory  1160  can store the MAC address of a paired partner earbud. 
     In another example once headphones  1010  are paired with host device  1030  or wearable device  1015 , the host device can save related pairing information from headphones  1010  to a network storage system  1115  such as cloud storage. In one embodiment the related pairing information stored in network storage  1115  can then be used by other host devices to be pre-paired with wireless headphones  1010 . As an illustrative example, in one embodiment wireless headphones  1010  can be initially paired with smartphone (e.g., an iPhone). A smartphone device can communicate the pairing information to the user&#39;s iTunes or iCloud account that can be saved on a remote network separate from host device  1030  (e.g., in the iCloud). The wireless headphones  1010  can then be listed on the user&#39;s iTunes or iCloud account as an authorized wireless device for the account. For example, the user&#39;s iCloud account may include a first list of host devices (one or more smart phones, one or more tablet computers and one or more laptop computers) including host device  1030  that are automatically authorized, for example based on the previous authorization and/or authentication of the devices to the iCloud account, to be paired with one or more wireless headphones that have been added to the account (including wireless headphones  1010 ). The user can then go to their tablet computer which can be automatically paired to the wireless headphones  1010  or multifunction accessory case  1005  without having to initiate a separate pairing sequence between headphones  1010  and the tablet computer based on the list of approved pairing in the user&#39;s iCloud account. Multiple host devices can be pre-authorized and automatically paired using this feature. 
       FIG. 12  depicts an illustration of the multiple exemplary communication paths for the system  1200  according to some embodiments of the disclosure. In some embodiments, a wearable device  1202  such as an electronic watch can synchronize the digital assets stored on or accessible by the wearable device  1202  with a mobile device  1204  such as a mobile phone or smartphone. In some embodiments, the wearable device  1202  can synchronize the digital assets with digital assets stored in a memory of the multifunction accessory case  1206 . In some embodiments, the wearable device  1202  can synchronize the digital assets with a cloud storage system  1208 . 
     In various embodiments, content stored on one device (e.g., a wearable device  1202 ) can be synchronized with a mobile device  1204  or multifunction accessory case  1206 . The mobile device  1204  or multifunction accessory case  1206  companion can have more processing power, more memory, more battery, or the like than the wearable device  1202 . The mobile device  1204  or multifunction accessory case  1206  can act as a proxy device to send and receive signals on behalf of other proxied devices. 
     Content synchronization may be performed by software (e.g., instructions or code modules) when executed by a central processing unit (CPU or processor) of a logic machine, such as a computer system or information processing device, by hardware components of an electronic device or application-specific integrated circuits, or by combinations of software and hardware elements. 
     A multifunction accessory case  1206  can determine whether an image collection has changed. An image collection may change due to a variety of reasons. For example, the multifunction accessory case  1206  can include a camera and any photos taken with the camera are stored in an image collection available on the multifunction accessory case  1206 , the wearable device  1202 , or the mobile device  1204 . In another example, a service (e.g., content infrastructure) to which the multifunction accessory case  1206  connects can provide instruction and/or content that modify the collection of images stored on the multifunction accessory case  1206 . In yet another embodiment, the multifunction accessory case  1206  can connect with a service such as a cloud storage  1208  that hosts an image collection. 
     In the course of this procedure according to one embodiment, the multifunction accessory case  1206  can maintain a set of identifiers that includes an identifier for all or part of the images in the image collection accessible to the multifunction accessory case  1206 . An image identifier may uniquely identify the image relative to the collection of images or to all images accessible to the multifunction accessory case  1206 . The multifunction accessory case  1206  can compare the set of identifiers that it maintains with a set of identifiers for the current collection of images. Any difference in missing identifiers or added identifiers may be used to determine that the image collection has changed. 
     The multifunction accessory case  1206  can generate a notification of the change and sends the notification to the mobile device  1204 . The notification can include any type or format of message that indicates that a change has occurred. In some embodiments, when the multifunction accessory case  1206  can be paired with a wearable device  1202  or a mobile device (e.g., mobile device  1204 ) that utilizes more energy efficient communication protocols, the multifunction accessory case  1206  can send a notification that at a minimum can be indicative of a dirty bit. The dirty bit can be recognized by the wearable device  1202  or the mobile device  1204  as indicating that new or updated content can be available at or through the multifunction accessory case  1206 . 
     The wearable device  1202  or the mobile device  1204  can generate a signature of an image collection stored on the wearable device  1202  or the mobile device  1204  and sends the signature to the multifunction accessory case  1206 . A signature of an image collection may include hash or other check performed on one device that if performed by another device on the same data set results in the other device computing the same value, hash, check. 
     The multifunction accessory case  1206  receives the signature from either the wearable device  1202  or the mobile device  1204  and generates a signature of the image collection available to it. If the signature generated by the wearable device  1202  or the mobile device  1204  can be the same as the signature generated by the multifunction accessory case  1206 , then no synchronization is needed between the devices. If the signature generated by the wearable device  1202  or the mobile device  1204  is different from the signature generated by the multifunction accessory case  1206 , the multifunction accessory case  1206  sends a set of identifiers that includes an identifier for all or part of the images in its image collection that can be made available on the wearable device  1202  or the mobile device  1204 . 
     The wearable device  1202  and/or the mobile device  1204  receives the set of identifiers and determines an action set based on the set of identifiers. In one embodiment, the wearable device  1202  or the mobile device  1204  determines an add action for each identifier in the set of identifiers that is not present in a set of identifiers maintained by the wearable device  1202  or the mobile device  1204  that includes an identifier for all or part of an image collection on the wearable device  1202  or the mobile device  1204 . The add action instructs the wearable device  1202  or the mobile device  1204  to retrieve the image associated with the new identifier from the multifunction accessory case  1206 . In another embodiment, the mobile device determines a delete action for each identifier in the set of identifiers maintained by the wearable device  1202  or the mobile device  1204  that is not present in the set of identifiers received from the multifunction accessory case  1206 . The delete action instructs the wearable device  1202  or the mobile device  1204  to remove the image associated with the missing identifier from the set of identifiers received from the multifunction accessory case  1206 . 
     In various embodiments, the wearable device  1202  or the mobile device  1204  determines an update action for one or more images in the image collection on the wearable device  1202  or the mobile device  1204 . The update action may be similar to an add action in that it instructs the wearable device or the mobile device  1204  to retrieve the image associated with the identifier from the multifunction accessory case  1206  even if the image already exists on the wearable device  1202  or the mobile device  1204 . The update action can further instruct the wearable device  1202  or the mobile device  1204  to retrieve update information from the multifunction accessory case  1206  for an image on the wearable device  1202  or the mobile device  1204 . The update information can include new data for a portion of the image, one or more edits or operations to be applied to the image to transform the image, or the like. 
     In various embodiments, the multifunction accessory case  1206  may send version information together with the set of identifiers. The wearable device  1202  and/or the mobile device  1204  can compare the version information received from the multifunction accessory case  1206  with its own version information. If a difference arises between the versions on an image, the wearable device  1202  and/or mobile device  1204  can determine to perform an add action or an update action. 
     The wearable device  1202  and/or mobile device  1204  can perform the action set. For an add action, the wearable device  1202  and/or mobile device  1204  may add a new identifier associated with an image accessible to the multifunction accessory case to a retrieval or download list. The wearable device  1202  and/or mobile device  1204  can retrieve or download the new image when the wearable device  1202  and/or mobile device  1204  is ready, for example, when battery conditions permit or when stable communications are available. For a delete action, the wearable device  1202  and/or mobile device  1204  may remove an image from its storage. The wearable device  1202  and/or mobile device  1204  may delete the image from its local storage or delete the identifier from the set allowing the image to be overwritten with a new image. 
     For an update action, the wearable device  1202  and/or mobile device  1204  may add a new identifier associated with an image accessible to the multifunction accessory case  1206  to the retrieval or download list if there are differences in version information. If the wearable device  1202  and/or mobile device  1204  knows that one or more edits or operations are to be applied to an existing image, the wearable device  1202  and/or mobile device  1204  can retrieve the edits or operations from the multifunction accessory case  1206 . 
     In some embodiments, each of the wearable device  1202 , the mobile device  1204 , and the multifunction accessory case  1206  may use the techniques described above to synchronize between a cloud storage  1208  and each of the devices. 
     In some embodiments, a connector interface and/or radio frequency interface can be used to support synchronization operations in which data can be transferred from a multifunction accessory case to a multifunction accessory case, a mobile device, or a cloud storage (or vice versa). For example, as described below, a user can customize certain information for multifunction accessory case  1206  (e.g., a “favorite” contacts list and/or specific predefined text messages that can be sent). While user interface can support data-entry operations, a user may find it more convenient to define customized information on a separate device (e.g., a tablet or smartphone) that has a larger interface (e.g., including a real or virtual alphanumeric keyboard), then transfer the customized information to the multifunction accessory case via a synchronization operation. Synchronization operations can also be used to load and/or update other types of data in storage subsystem, such as media items, application programs, and/or operating system programs. Synchronization operations can be performed in response to an explicit user request and/or automatically, e.g., when the multifunction accessory case  1206  resumes communication with a particular host device or in response to either device receiving an update to its copy of synchronized information. The synchronization can occur over a wireless signal such as Wi-Fi, Bluetooth or cellular signal. 
     The communication of data from a device (e.g., wearable device  1202 , the mobile device  1204  or multifunction accessory case  1206 ) can occur through various protocols (e.g., 802.11 protocols, Bluetooth protocols, and near field communication (NFC) protocols). To determine which protocol to use, a device can include a link manager for determining which protocol to use for a particular application, and thus which driver path data can be sent. Although only a few communication protocols are listed, numerous wireless protocols can be used. For example, Bluetooth protocols can include Basic Rate (BR), Enhanced Data Rate (EDR), and Low Energy (LE) options. Bluetooth BR/EDR can be also referred to as Classic Bluetooth. 
     Representative applications of apparatuses and methods according to the presently described embodiments are provided in this section. These examples are being provided solely to add context and aid in the understanding of the described embodiments. It can thus be apparent to one skilled in the art that the presently described embodiments can be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order to avoid unnecessarily obscuring the presently described embodiments. Other applications are possible, such that the following examples are not as limiting. For example, in some embodiments, the case can store more than two earbuds. In some embodiments, the housing may appear different as additional features are added. 
     In the foregoing specification, embodiments of the disclosure have been described with reference to numerous specific details that can vary from implementation to implementation. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense. The sole and exclusive indicator of the scope of the disclosure, and what can be intended by the applicants to be the scope of the disclosure, is the literal and equivalent scope of the set of claims that issue from this application, in the specific form in which such claims issue, including any subsequent correction. The specific details of particular embodiments can be combined in any suitable manner without departing from the spirit and scope of embodiments of the disclosure. 
     As described above, one aspect of the present technology is the gathering and use of data available from various sources such as the collection of health data from various sensors. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, twitter ID&#39;s, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to calculate progress towards health or fitness objectives. Accordingly, use of such personal information data can be presented to a user on the display. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user&#39;s general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of collecting sensor data, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide personal information to be displayed in non-rectangular areas. In yet another example, users can select to limit amount of personal data is maintained or entirely prohibit the display of personal data. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the bounding path techniques, or publicly available information. 
     It is well understood that the use of personally identifiable information should follow privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining the privacy of users. In particular, personally identifiable information data should be managed and handled so as to minimize risks of unintentional or unauthorized access or use, and the nature of authorized use should be clearly indicated to users. 
     Although the foregoing disclosure has been described in detail by way of illustration and example for purposes of clarity and understanding, it can be recognized that the above described devices may be embodied in numerous other specific variations and embodiments without departing from the spirit or essential characteristics of the devices. Certain changes and modifications may be practiced, and it is understood that the disclosure is not to be limited by the foregoing details, but rather is to be defined by the scope of the appended claims. 
     Additionally, spatially relative terms, such as “bottom” or “top” and the like can be used to describe an element and/or feature&#39;s relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It can be understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as a “bottom” surface can then be oriented “above” other elements or features. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
