For example, the earbud may be configured to detect gestures, physical manipulations, and so forth performed along or on the earbud. In response to the detected inputs, the earbud may be configured to change various outputs, such as an audio output or a haptic output of the device. The earbud may also include a microphone to register voice commands. In some cases, the microphone may be used to control the earbud using the registered voice command in response to one or more detected gestures or physical manipulations.

In many cases, the earbud requires a hardwired connection that physically couples the earbud to another device and the sound is controlled based on input received at the device. Further, earbuds and/or other connected devices may be unresponsive to voice commands, thereby limiting the adaptability of the earbud to control multiple types of functions.

     DETAILED DESCRIPTION 
     The description that follows includes sample systems, methods, and apparatuses that embody various elements of the present disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms in addition to those described herein. 
     The present disclosure describes systems, devices, and techniques related to a wearable audio device, such as an earbud or other device that may be worn at least partially in an ear of a user. The wearable audio device may form a sealed passage with an ear canal of the user when worn. A speaker of the wearable audio device may provide audio output through the sealed passage. The audio output may include music, voice communications, instructions, sounds, alerts, and so forth. The audio output may be initiated or controlled by a processing unit of the wearable audio device and/or an associated companion device, as described herein. The audio output may be responsive to various types of input received at the device, including touch and gesture inputs and physical manipulations of controls or other tactile structures. 
     The audio output may also be responsive to audio input, such as voice commands, received at the wearable audio device. The processing unit may distinguish between the various types of input in order to control one or more functions of the wearable audio device. For example, voice commands may be used to control music playback (e.g., play, pause, volume up/down), answer or end a call, interact with an intelligent digital assistant, and so forth. In some cases, voice commands may be used to control the device in response to detecting another type of input, such as a touch or a gesture. This may allow the wearable audio device to operate in various modes, including a first mode in which audio input is temporarily ignored, and a second mode in which identified voice commands are used to control the device. 
     To facilitate the foregoing, the wearable audio device may include one or more sensors that detect different types of input. Broadly, the sensors may include substantially any input device, sensor, sensing element, sensing structure, switch, or the like, or combination thereof, that is responsive to environmental changes around the wearable audio device. As one example, an incorporated sensor may detect a touch or proximity of a user or object to the wearable audio device. Continuing the example, a capacitive sensor may be incorporated into an enclosure of the wearable audio device and used to detect a capacitance between an electrode of the sensor and the user. As the user moves toward (and optionally presses on) the enclosure, the capacitance changes. This change (or absolute value of the capacitance) may be used to determine a position of a user&#39;s finger relative to the enclosure. 
     Likewise, an array of capacitive sensors may be operatively coupled to one another and used to track movement of the user along the enclosure. This may allow the wearable audio device to detect multiple gestures on or along the enclosure (e.g., a first gesture input, a second gesture input, and so on). For example, the sensor may detect a first direction of a gesture input and a second direction of a gesture input along the enclosure (or other directions, motions, and so on the gesture input). The processing unit of the wearable audio device may, in turn, initiate one or more functions of the wearable audio device based on the detected input, such as increasing a playback volume in response to the first direction of motion and/or decreasing playback volume in response to the second direction of motion, among other possible functions. 
     It will be appreciated that various types of sensors may be used to detect a touch, gesture, or the like at the enclosure and are described in greater detail below. For example, one or more optical sensors may be positioned within the enclosure and may detect a location of a user&#39;s hand, finger, or other object. An optical coating (transparent only to certain wavelengths) may substantially conceal the optical sensor from a user by camouflaging a lens and/or protective window of the sensor with the surrounding enclosure. Magnetic sensors, strain sensors, resistive sensors, and electroactive polymers (EAPs) may be used to detect such input at the wearable audio device, as described in greater detail below. 
     Additionally or alternatively, one or more tactile structures may be incorporated within or along an exterior of the enclosure and detect input at the wearable audio device. Broadly, a tactile structure may be substantially any physical feature of the device enclosure, including a button, switch, or other control, that may be physically manipulated by a user. Possible structures include textured surfaces of the enclosure, multi-input domes, rotary wheels and/or crowns, deformable stems, and so on. In some cases, the tactile structure may be configured to provide haptic feedback to the user in response to such manipulation, which may indicate receipt of input by the wearable audio device. Haptic feedback may be provided in part by forming the tactile structure from domes, beams, or other deformable materials and/or coupling the tactile structure with various electrically or thermally actuated haptic structures, as described herein. 
     Various sensors may be configured to detect manipulation of the tactile structure (e.g., a first manipulation, a second manipulation) and provide a corresponding signal that may be used to control, for example, the audio output and/or other global functions of the wearable audio device. For example, the sensors may detect a squeeze, a rotation, a swipe, a press, a jog, and so on of the tactile structure. To illustrate, where the tactile structure is a wheel, the sensors may detect a first rotation of the wheel and a second rotation of the wheel (or other physical manipulation), and the audio output may be responsive to each of the detected rotations. As another example, when the tactile structure is a textured surface of the enclosure, the sensor may detect a first swipe of the textured surface and a second swipe of the textured surface (or other manipulation), and the audio output may be responsive to each of the detected swipes. In this manner, the tactile structure may be used to indicate a boundary or region of the enclosure that may be touch-sensitive. For example, a user may tactilely perceive a change in surface texture between a surrounding device enclosure and the tactile structure, which signifies a region of the device that receives touch input. This may allow the user to accurately perform a gesture or other input on the enclosure while the wearable audio device is worn in the ear, or while the user is otherwise not visually perceiving the enclosure. In other cases, other tactile structures may be used and are described in greater detail herein, including embodiments in which multiple different tactile structures and/or combination of tactile structures and sensors are used to detect physical manipulations and/or gestures inputs at the enclosure. 
     For example, in an embodiment, the sensors may include one or more microphones positioned at least partially within the enclosure of the wearable audio device. As stated above, one microphone may detect voice commands that are used by the on-board processing unit to control, for example, the audio output of a speaker. This microphone may also be operatively coupled to another sensor (via the processing unit) so that such voice commands are accepted in conjunction or succession with another input, such as a touch input in a particular location on the device. Another microphone may detect other types of input, including input received by a body (e.g., head) of a user. For example, the microphone may detect an acoustic signal associated with a tap of a user&#39;s hand on a portion of the user&#39;s head, a click of a user&#39;s teeth, and/or other body movement that may be associated with input. This may allow the user to control audio output or another function of the device without necessarily physically contacting the wearable audio device and/or any associated companion device, thereby improving the adaptability of the system. This may also increase the interaction area that may receive input and reduce acoustic impacts of tapping the wearable audio device, among other improvements. Other microphones may be used and are described in greater detail below, including various beam forming and other microphones that may be used to detect and filter ambient noise. 
     The wearable audio device may include various structural components that house the sensors and tactile structures described herein. The enclosure of the wearable audio device may generally define an earbud body, which is shaped or otherwise contoured to be at least partially received within an ear of a user. The enclosure may have an interior volume that houses the sensors, speakers, microphones, processing unit(s), and other components and define an opening that allows the audio output from the speaker to exit. A sealing component, such as an elastic or deformable ring, may be positioned around the opening and configured to form a sealed passage between the interior volume and an ear canal of the user. To facilitate the forgoing, the sealing component may have a conformable surface that contacts the user&#39;s outer ear and engages, for example, the concha, the antihelix, the helix, or the like, in order to form the seal. 
     The enclosure may also have, or be formed from, various structural components that facilitate detection of input and/or receipt of the device within a user&#39;s ear. For example, in an embodiment, the enclosure may include a main unit and a stem. The main unit may define the opening through which audio output is provided to the user. The stem may extend from the main unit and include additional sensors, including touch sensors, and beam-forming microphones. The stem may generally be an elongated structure and, in some cases, house an antenna or other communications device. Both the main unit and the stem may be configured to receive a touch or gesture input and/or physical manipulation, as described herein. As a non-limiting illustration, the main unit may define a substantially uninterrupted external surface that may be used to receive a swipe of various directions or other gestures. As another illustration, the stem may be squeezed, rotated, or otherwise physically manipulated in order to provide input. It will be appreciated, however, that the main unit and the stem are presented herein for purposes of discussion, and that the enclosure of the wearable audio device may take substantially any shape to facilitate the various functions described herein. 
     Reference will now be made to the accompanying drawings, which assist in illustrating various features of the present disclosure. The following description is presented for purposes of illustration and description. Furthermore, the description is not intended to limit the inventive aspects to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the present inventive aspects. 
       FIG. 1A  depicts a functional block diagram of a wearable audio device  100 , such as the wearable audio device discussed above and described in greater detail below. The wearable audio device  100  includes one or more input devices  110 , one or more output devices  140 , and a processing unit  150 . Broadly, the input devices  110  detect various types of input, and the output devices  140  provide various types of output. The processing unit  150  receives input signals from the input devices  110  in response to inputs detected at the input devices. The processing unit  150  may interpret input signals received from one or more input devices  110  and send output signals to one or more output devices  140  that instruct the output devices  140  to provide output. Detected input at one or more input devices  110  may be used to control one or more functions of the wearable audio device  100 . In this regard, the output devices  140  may be configured to provide outputs that may be manipulated based on the input detected at the input devices  110 . The outputs provided by the output devices  140  may also be responsive to, or initiated by, a program or application executed by a processing unit of the wearable audio device  100  and/or an associated companion device. 
     In various embodiments, the input devices  110  may include any suitable components for detecting inputs. Examples of input devices  110  include audio sensors (e.g., microphones), optical or visual sensors (e.g., cameras, visible light sensors, invisible light sensors), proximity sensors, touch sensors, force sensors, mechanical devices (e.g., switches, buttons, keys), vibration sensors, orientation sensors, motion sensors (e.g., accelerometers, velocity sensors), location sensors (e.g., GPS devices), thermal sensors, communication devices (e.g., wired or wireless communication devices), resistive sensors, magnetic sensors, electroactive polymers (EAPs), strain gauges, and so on, or some combination thereof. Each input device  110  may be configured to detect one or more particular types of input and provide a signal (e.g., an input signal) corresponding to the detected input, for example to the processing unit  150 . 
     The output devices  140  may include any suitable components for providing outputs. Examples of output devices  140  include audio output devices (e.g., speakers), visual output devices (e.g., lights, displays), tactile output devices (e.g., haptic output devices), communication devices (e.g., wired or wireless communication devices), or some combination thereof. Each output device  140  may be configured to receive one or more signals (e.g., an output signal), for example from the processing unit  150 , and provide an output corresponding to the signal. 
     The processing unit  150  is operably coupled to the input devices  110  and the output devices  140 . The processing unit  150  is adapted to exchange signals with the input devices  110  and the output devices  140 . For example, the processing unit  150  may receive an input signal from an input device  110  that corresponds to an input detected by the input device. The processing unit  150  may interpret the received signal to determine whether to provide and/or change one or more outputs in response the input. The processing unit  150  may then send an output signal to one or more output devices  140  to provide and/or change outputs as appropriate. The processing unit  150  may include one or more computer processors or microcontrollers that are configured to perform operations in response to computer-readable instructions. Examples of suitable processing units are discussed in more detail below with respect to  FIG. 16 . 
     As discussed above, in some embodiments, the input devices  110  include one or more microphones used to detect audio input. The audio input may include voice commands, vibrations, bodily noises, ambient noise, or other acoustic signals. In some cases, the wearable audio device  100  may have one or more dedicated microphones that are configured to detect particular types of audio input. For example, the wearable audio device  100  may include a first microphone, such as a beamforming microphone, that is configured to detect voice commands from a user, a second microphone that is configured to detect ambient noise, and a third microphone that is configured to detect acoustic signals or vibrations from a user&#39;s body (such as that produced by a facial tap or other gesture). 
     The processing unit  150  may receive a signal from each microphone and distinguish between the various types of input. For example, the processing unit  150  may identify a signal from the microphone(s) associated with an input (e.g., a voice command, a facial tap, and so on) and initiate a signal that is used to control a corresponding function of the wearable audio device  100 , such as an output provided by an output device  140 . The processing unit  150  may also identify signals from the microphone(s) associated with an ambient condition and ignore the signal and/or use the signal to control an audio output of the wearable audio device  100  (e.g., a speaker), such as acoustically cancelling or mitigating the effects of ambient noise. 
     One or more input devices  110  may operate to detect a location of an object or body part of a user relative to the wearable audio device  100 . This may also include detecting gestures, patterns of motion, signs, finger or hand positions, or the like, including detecting a direction of the input, such as a direction of a gesture along an x-axis, a y-axis, and/or a z-axis. To facilitate the foregoing, the wearable audio device  100  may include a capacitive sensor that is configured to detect a change in capacitance between an electrode of the sensor and a user. As the user approaches the sensor, the capacitance changes, and thus may be used to determine a distance of the user relative to the electrode. In this manner, multiple capacitive sensors may be used to track a location or position of a body part of the user along an exterior surface of the wearable audio device  100 . 
     In some cases, the capacitive sensor may also be used to measure or detect a force input on an exterior surface of the wearable audio device  100 . For example, the user may press the exterior surface and deform it toward the electrode of the sensor. The surface may deform by a known amount for a given force, and thus a force applied by the user to the surface may be determined based on the positioned of the user derived from the change in capacitance. 
     As discussed above, the wearable audio device  100  may also include one or more visual or optical sensors. The optical sensors may, in certain embodiments, measure an intensity of light at one or more locations on the exterior surface of the wearable audio device  100 . A decrease in the intensity of light at a particular location may be associated with a user input or gestures, such as a cupping gesture over the wearable audio device  100 . A lens or protective window of the optical sensor may be camouflaged from a surrounding surface of the wearable audio device  100 , for example, using an optical coating, which may match the surrounding surface but be translucent to certain wavelengths of light. In other embodiments, the optical sensor may be, or form a component of, a camera or camera system. This may allow the wearable audio device  100  to detect and recognize specific types of gestures using pattern recognition. 
     Optical sensors, in certain embodiments, may also be used to detect a location of the wearable audio device  100 . For example, an optical sensor may be positioned relative to a portion of the wearable audio device  100  configured to be worn in a user&#39;s ear. This may allow the optical sensor to detect a receipt of the wearable audio device  100  within a person ear (e.g., in response to a decrease in light intensity measured at the sensor). 
     The input devices  110  may also include one or more mechanical devices or tactile structures that are configured to receive physical input or manipulations. Physical manipulations may include a squeeze, a collapse, a roll or rotation, a jog, a press, a pull, and so on. In some cases, the physical input may manipulate the mechanical device or tactile structure and cause the mechanical device or tactile structure to physically complete a switch or circuit that triggers a switch event. In other cases, the physical manipulation of the tactile structure is detected or recognized by substantially non-contact types of sensors or switches of the wearable audio device  100 , such as an optical reader detecting the rotation of a wheel, and so on. The mechanical device or tactile structure may therefore take various forms, including a textured exterior surface, a multi-input button or dome, a wheel, a crown, and so on. 
     The wearable audio device  100  may include various other components and sensors that are configured to detect input. In one embodiment, the wearable audio device  100  may include an antenna that is configured to communicatively or wirelessly couple the wearable audio device  100  to another device, such as the companion device  170  described below with respect to  FIG. 1B . Accordingly, the wearable audio device  100  may be configured to receive input signals from other devices such as the companion device  170 . As described above, the inputs may be used to control one or more outputs of the wearable audio device  100 , such as an audio output. 
     As a further example, the input devices  110  may include a thermal sensor to detect the placement of the wearable audio device  100  within a user&#39;s ear. Accelerometers and speed sensors may be used to detect changing conditions, for example, when the wearable audio device  100  is used or otherwise worn by a user driving an automobile. In other cases, other combinations of sensors and associated functionalities are possible and contemplated herein. 
     As described above, an input device  110  may initiate or provide a signal corresponding to an input detected at the input device. The signal may be provided to the processing unit  150  and used to control one or more outputs of the wearable audio device  100 . In this regard, the wearable audio device  100  may include various output devices  140  in order to provide outputs and alter or manipulate the outputs based on detected inputs. 
     The output devices  140  may include one or more audio output devices, such as speakers, configured to produce an audio output, such as various types of music, voice communications, instructions, sounds, alerts, other acoustic signals, or some combination thereof. In some embodiments, the speakers have a relatively small form factor corresponding to that of the wearable audio device  100  so that the speakers may be disposed within an enclosure of the wearable audio device  100 . For example, the speaker may generally have a maximum dimension within a range of several millimeters, however other dimensions are possible. Notwithstanding, the speaker may be configured to provide substantially high resolution audio output to a user. This may be facilitated by the various components (e.g., sealing component  322  of  FIG. 3A ) described herein that are used define a sealed passage between an interior volume of the wearable audio device  100  (which houses the speaker) and the user&#39;s ear canal. The speaker may also be tuned to operate in one or more modes that facilitate canceling or mitigating ambient noise detected by, for example, one or more of the microphones of the wearable audio device  100 . For example, various characteristics of the audio output may be altered, for example by the processing unit  150 , in order to compensate for the interference of the ambient noise. 
     Audio outputs may be configured to change in response to inputs received at the wearable audio device  100 . For example, the processing unit  150  may be configured to change the audio output provided by a speaker in response to an input corresponding to a gesture input, physical manipulation, voice command, and so on. The speaker may thus receive multiple distinct signals from the processing unit  150  corresponding to different types of input or otherwise corresponding to distinct functions. To illustrate, a first signal corresponding to a direction of a first gesture input may cause the processing unit  150  to alter the audio output in a first manner (e.g., such as increasing playback volume in response to an up swipe), and a second signal corresponding to a direction of a second gesture input may cause the processing unit  150  to alter the audio output in a second manner (e.g., such as decreasing playback volume in response to a down swipe), among other possibilities. 
     The output devices  140  may include one or more tactile output devices configured to produce a tactile or haptic output. Haptic outputs may be facilitated by a haptic feedback structure, such as a dome, electromechanical actuator, and so forth. The output devices  140  may include one or more tactile structures to provide a tactile indication of, for example, the receipt of input by the wearable audio device  100 . This may include a buckling of a collapsible dome, or other deformation of a structure that registers input in response to a physical manipulation. Additionally or alternatively, a tactile structure may visually and/or tactilely indicate a region of the wearable audio device  100  operable to receive input. For example, a textured surface may provide a tactile output to a user as the user feels the changing contours of the surface. 
     The output devices  140  may include one or more visual output devices configured to illuminate or otherwise visually alter a portion of the wearable audio device  100 , such as an exterior surface. Various lights or visual indicators may be used to produce a visual output of the wearable audio device  100 . The visual output may be indicative of an operational status of the wearable audio device  100 . For example, the visual output may include certain colors that represent a power-on mode, a standby mode, a companion-device pairing mode, a maintenance mode, and so on. 
     Visual output may also be used to indicate a receipt of input by the wearable audio device  100 . As one possibility, visual indicators along a surface of the wearable audio device  100  may produce a momentary flash, change colors, and so on, in response to received inputs. In this regard, the visual output may be responsive or adaptable to the various different types of input detected or that otherwise correspond to distinct functions of the wearable audio device  100 . This may include producing a first visual output (e.g., a first color, animation, or sequence) in response to a first input (audio, gesture, mechanical, and so forth) and producing a second visual output (e.g., second color, animation, or sequence) in response to a second input (audio, gesture, mechanical, and so forth). 
     Additional or alternative output devices  140  may generally be configured to produce other types of output, including, but not limited to, thermal outputs, pressure outputs, outputs for communication to external or companion devices, and so on. In one embodiment, the wearable audio device  100  may include an antenna that is configured to communicatively or wirelessly couple the wearable audio device  100  to another device, such as the companion device  170  described below with respect to  FIG. 1B . The wearable audio device  100  may thus transmit an output signal from the to the companion device  170  that may be used to control one or more outputs of the companion device  170 , such as an audio output. 
     The input devices  110  and the output devices  140  described with respect to  FIG. 1A  may include a collection of mechanical components, sensors, instruments, processing unit(s), computer-readable instructions, and so forth that collectively operate to perform the functions described herein. Rather than define discrete or isolated systems, it will be appreciated that the devices may use common or overlapping components to perform the described functions. Further, in addition to those described with respect to  FIG. 1A , the wearable audio device  100  may include any other appropriate hardware (e.g., sensors, switches, antennas, processing units, memories), software (e.g., applications, system programs, engines), network components (e.g., communication paths, interfaces, routers), and so forth for use in facilitating any operations disclosed herein, for example, such as those described below with respect to  FIG. 16 . 
       FIG. 1B  depicts a functional block diagram of a wearable audio device (such as the device of  FIG. 1A ) and a companion device  170 . In particular, the wearable audio device  100 , described above with respect to  FIG. 1A , is shown communicatively coupled with a companion device  170 . The companion device  170  may be substantially any computing device that is configured to receive input and initiate a signal that is used to control the wearable audio device  100 . In some embodiments, the functionality of the companion device  170  is provided by the wearable audio device  100 . Sample companion devices include, but are not limited to, a personal computer, a notebook computer, a tablet, a smart phone, a watch, a case for the wearable audio device  100 , a home automation device, and so on. Example companion devices, and corresponding structures are described herein, for example, with respect to  FIGS. 12-16 . 
     The wearable audio device  100  and the companion device  170  may be communicatively coupled via a wireless connection. For example, the wearable audio device  100  may be paired with the companion device  170  using a short range wireless interconnection; however, other wireless connection techniques and protocols may be used. In other embodiments, the wearable audio device  100  and the companion device  170  may be connected via a wired connection. 
       FIG. 1B  depicts various functional modules of the companion device  170 . Each functional module or submodule described with respect to  FIG. 1B  may include a collection of mechanical components, sensors, instruments, processing unit(s), computer-readable instructions, and so forth that collectively operate to perform the functions described herein. It will be appreciated that the companion device  170  also may include any appropriate hardware, software, network components, and so forth for use in facilitating any operations disclosed herein, for example, such as those described below with respect to  FIG. 16 . 
     For purposes of illustration, the companion device  170  includes at least a context module  175 , an input module  180 , and an output module  185 . Broadly, the context module  175  may be configured to provide an operational context to the wearable audio device  100 . An operational context may be, or include, information associated with an application or program executed on the companion device  170  (e.g., such as an application executed by the processing unit  1608  of  FIG. 16 ). The operational context may therefore be used by the wearable audio device  100  to provide an output, such as a music output (where the executed program is an audio file), a voice communication output (where the executed program is a telephone call), an audio notification output (where the executed program is a navigation application), among various other possibilities. 
     The operational context may also be used by the wearable audio device  100  to determine or activate a particular type of input or sensor. For example, different types of gestures, audio input, physical manipulations, and so forth may be registered as input (or ignored) based on the operational context. To illustrate, where the operational context causes the wearable audio device  100  to output music, the processing unit  150  may be configured to control the music based on a direction of motion of a received input (e.g., such as a swipe in a first direction, a second direction, and so on). In another mode, where the operational context causes the wearable audio device  100  to output voice communications, the processing unit  150  may be configured to control the music based on a physical manipulation of a tactile structure (and ignore gesture inputs), among various other possibilities. 
     With reference to the input module  180 , the companion device  170  may be configured to receive input using various different sensors and structures. For example, and as described in greater detail below with respect to the sample companion devices of  FIGS. 12-16 , the companion device  170  may include mechanical buttons, keyboards, touch-sensitive surfaces, trackpads, microphones, and other sensors. The input detected by the input module  180  may be used to control an output of the wearable audio device  100 . As one example, an audio playback volume may be increased or decreased in response to a manipulation of one or more mechanical keys or buttons of the companion device  170 . The input detected by the input module  180  may also be used to control a mode of the wearable audio device  100 , such as a mode for detecting certain audio inputs. For example, the wearable audio device  100  may be configured to enter a mode in which audio input is used to control a function of the wearable audio device  100  and/or the companion device  170 . 
     With reference to the output module  185 , the companion device  170  may be configured to provide output using various different components and structures. For example, and as described in greater detail below with respect to the sample companion devices of  FIG. 11-16 , the companion device  170  may include speakers, a display, tactile structures, and other components. The output provided by the output module  185  may be responsive to input detected by the wearable audio device  100 . As one example, in response to a detection of input at the wearable audio device  100 , a graphic may be depicted at a display of the companion device  170 , or, likewise, a sound may be produced at a speaker of the companion device  170 . The output module  185 , more generally, may also be used to indicate a status of the wearable audio device  100  to a user. For example, the output module  185  may produce an output, visual or otherwise, corresponding to different modes of the wearable audio device  100 , including a power-on mode, a standby mode, a battery status level, among various other indications. 
       FIG. 2  depicts wearable audio devices  200  worn by a user  250 . The wearable audio devices  200  may be a pair of devices, such as a first wearable audio device  200   a  and a second wearable audio device  200   b , shown in  FIG. 2 . Each of the first wearable audio device  200   a  and the second wearable audio device  200   b  may be substantially analogous to the wearable audio device  100  described above with respect to  FIGS. 1A and 1B . For example, the wearable audio devices  200  may each be configured to detect input (e.g., audio, gesture, physical manipulation, and so on) and alter an audio or other output based on the detected input. In this regard, it will be appreciated that the wearable audio device  200  may include similar components and/or be configured to perform similar functions as the wearable audio device  100  described above. Redundant explanation of these components is omitted here for clarity. 
     The wearable audio devices  200  may be worn by the user  250 , as shown in  FIG. 2 . In particular, the wearable audio devices  200  may be configured to be received and temporarily secured at an outer ear of the user  205 . In some cases, at least a portion of each of the wearable audio devices  200  may engage or seal a portion of a user&#39;s ear (such as forming a seal around an ear canal). This may support the device within the ear, and optionally form a sealed passage between various audio output components of the device and an ear canal of the user  250 . In the embodiment of  FIG. 2 , the first wearable audio device  200   a  may be positioned at least partially within a first ear  260   a  of the user  250 , and the second wearable audio device  200   b  may be positioned within a second ear  260   b  of the user  250 . While  FIG. 2  shows the user  250  wearing both the first wearable audio device  200   a  and the second wearable audio device  200   b , it will be appreciated that in some cases a user  250  may optionally wear a single one of the first wearable audio device  200   a  or the second wearable audio device  200   b . Further, notwithstanding the wearable audio devices  200  being configured to form a sealed passage with an ear canal of the user  250 , each of the wearable audio devices  200  may be selectively removable by the user  250 , and therefore allow the user  250  to wear and remove the wearable audio devices  200  as needed or desired. 
       FIG. 2  also shows the user  250  holding a companion device  290 . The companion device  290  may be substantially analogous to the companion device  170  described above with respect to  FIG. 1B . The companion device  290  may be wirelessly coupled with the wearable audio devices  200 . In some cases, the companion device  290  may be configured to transmit information or commands associated with an operational context to one or both of the wearable audio devices  200 . This may include information corresponding to an application or program executed on the companion device  290 . For example, the companion device  290  may execute a music playback program, and thus the companion device  290  may provide information to the wearable audio devices  200  corresponding to the playback. The wearable audio device  200  may receive the information associated with the operational context and provide an output to the user  250  based on the received information. For example, upon receipt of the music playback information, the wearable audio devices  200  may be configured to provide an audio output to the user  250  that is, or includes, the music playback executed by the companion device  290 . 
     The wearable audio device  200  may also detect input. This may be used to control, for example, a function of the wearable audio device  200  (e.g., as indicated by a manipulation of an output of the device) or a function of the companion device  290 . In some cases, each of the wearable audio devices  200  may detect the same type of input and/or otherwise be used to redundantly control the same function. This may be the case, for example, where each of the wearable audio devices  200  is used to control playback volume of an audio output in response to a swipe along an exterior surface of either device. Additionally or alternatively, each of the wearable audio devices  200  may detect different types of input and/or be used to control different functions. This may be the case where, for example, the first wearable audio device  200   a  is used to control a first function (e.g., play track) in response to an input, and the second audio device  200   b  is used to control a second function (e.g., stop track) in response to another input. Such controls may be interchangeable, programmable, or otherwise based at least partially on the operational context provided by the companion device  290 . Further, while  FIG. 2  shows the wearable audio device  200  and the companion device  290 , it will be appreciated that the wearable audio device  200  may operate independently from any companion device. For example, and as described herein with respect to  FIG. 16 , applications, programs, or the like may be executed exclusively on one or both of the first wearable audio device  200   a  or the second wearable audio device  200   b , without necessarily pairing the devices to another external device. The wearable audio device  200  are shown as earbuds in  FIG. 2  as one example. In various embodiments, the wearable audio device  200  may take different forms, including as all or part of a headband, lanyard, or other object. In some embodiments, the wearable audio device  200  may be a part of a headset, such as a virtual reality headset. 
       FIG. 3A  depicts a wearable audio device  300  and a user  350 . The wearable audio device  300  is shown in  FIG. 3A  separated from the user  350 . In this regard, rather than being worn, the wearable audio device  300  is shown in  FIG. 3  as occupying a position that allows the user  350  to readily advance the wearable audio device  300  toward an ear  360  of the user  350 . The ear  360  may generally include an ear surface  364 . The wearable audio device  300  may be configured to engage and form a seal with the ear surface  364 . This may allow the wearable audio device  300  to provide an audio output directly to the user  350 , such as through a sealed passage defined between the audio component of the wearable audio device  300  and the user  350 . 
     To facilitate the foregoing,  FIG. 3A  shows a sample construction of the wearable audio device  300 . In particular,  FIG. 3A  shows the wearable audio device  300  as including an enclosure  310  and a sealing component  322 . The enclosure  310  may define an interior volume containing various sensors, output devices, and other components of the wearable audio device  300 . The enclosure  310  may have a form factor that allows the wearable audio device  300  to fit at least partially in the ear  360  of the user  350 . While the enclosure  310  may take many forms, in certain embodiments, such as that shown in  FIG. 3A , the enclosure  310  may include a main unit  314  and a stem  318 . Each of the main unit  314  and the stem  318  may house the input and/or output components of the wearable audio device  300 , as appropriate for a given application. In one embodiment, the main unit  314  may house relatively larger components of the wearable audio device  300 , such as a speaker or processing unit, and the stem  318  may house components of the wearable audio device  300  that may benefit from the elongated shape of the stem  318 , such as various microphones, antennas, and so on. 
     The enclosure  310  may be connected to the sealing component  322 . In some embodiments, the sealing component  322  may be fitted or positioned around a side of the enclosure  310 . For example, the enclosure  310  may define a speaker opening and the sealing component  322  may be positioned around this opening. The sealing component  322  may be connected to the enclosure  310  and configured to define a sealed passage from the opening to an ear of a user. As such, the sealing component  322  may be permanently affixed to the enclosure  310 . In other cases, as described herein, the sealing component  322  may be connected to the enclosure  310  in a manner that allows the sealing component to be removed, adjusted, replaced, and so on. The use of the term “connected to” embraces both these options. 
     The sealing component  322  may be configured to engage the ear  360  of the user  350 . For example, the sealing component  322  may include a conformable surface  324  that may be pressed into the ear surface  364 . In some cases, this may form or define a sealed passage between internal acoustic components of the wearable audio device  300  and, for example, an ear canal of the user  350 . Accordingly, the sealing component  322  may be formed from a variety of materials, including elastically deformable materials, such as silicon, rubber, nylon, and various other synthetic or composite materials. As described herein, the sealing component  322  may, in some embodiments, be removable from the enclosure  310  by the user  350 . This may allow the user  350  to interchange various different sealing components with the enclosure  310  of the wearable audio device  300  based on user customizable preferences. 
       FIG. 3B  depicts a cross-sectional view of the ear  360  of the user  350 , taken along line A-A of  FIG. 3A . Broadly, the ear  360  may include an outer ear region  370 , a middle ear region  372 , and an inner ear region  374 .  FIG. 3B  shows various features of the ear  360  that may be coupled with the wearable audio device  300  when the wearable audio device  300  is worn by the user  350 . For example, features of the outer ear region  370  may include a helix  376 , an antihelix  378 , a concha  380 , an auricular lobule  382 , and an ear canal  384 , among other features. The ear canal  384  may extend from an external opening of the outer ear region  370 , through the middle ear region  372 , and towards the inner ear region  374  where acoustic signals from the wearable audio device  300  may be processed by the user  350 . 
       FIG. 4A  depicts the wearable audio device  300  and the user  350 . In particular,  FIG. 4A  depicts a configuration in which the wearable audio device  300  is worn by the user  350 . For example, the wearable audio device  300  may be received at least partially within the ear  360  of the user  350 . When the wearable audio device  300  is worn by the user  350 , the sealing component  322  may be pressed into the ear  360 , thereby causing the conformable surface  324  of the sealing component  322  to contact and conform or partially conform to the ear surface  364 . This may allow the sealing component  322  to form a sealed passage between various audio output components of the wearable audio device  300  and, for example, an ear canal of the user. 
       FIG. 4B  depicts a cross-sectional view of the ear  360  of the user  350 , taken along line B-B of  FIG. 4A , and the worn wearable audio device  300 . As shown in  FIG. 4B , the wearable audio device  300  may be at least partially received with the ear  360 . For example, the sealing component  322  may be received within a portion of the outer ear region  370 . The sealing component  322  may contact various features of the outer ear region  370  and form a seal about the ear canal  384 . For example, the sealing component  322  may contact one or more of the helix  376 , the antihelix  378 , the concha  380 , and/or various other features of the outer ear region  370  that may be positioned about the ear canal  384 . 
     As described herein, the sealing component  322  may form or facilitate a sealed passage between various internal components of the wearable audio device  300  and the ear canal  384  of the user  350 .  FIG. 4B  shows a sealed passage  330 . The sealed passage  330  may extend from an interior volume  311  of the enclosure  310  to the ear canal  384 . The sealed passage  330  may allow the wearable audio device  300  to propagate audio outputs into the ear canal  384 , while mitigating or preventing the audio output from being released into a surrounding environment. For example,  FIG. 4B  shows a speaker  334  providing an acoustic signal A 1  through the sealed passage  330  and into the ear canal  384 . This may improve sound quality and also allow the sealing component  322  to block ambient noises or other environmental containments from entering the ear canal  384 . 
       FIG. 5  depicts a wearable audio device  500  worn by a user  550 . The wearable audio device  500  may be substantially analogous to the wearable audio devices described herein. The wearable audio device  500  may therefore include similar components and/or perform similar functions of other wearable audio devices described herein, redundant explanation of which is omitted here for clarity. 
     The wearable audio device  500  is shown positioned partially within an ear  560  of the user  550 . For example, the wearable audio device  500  may be at least partially received by one or more components of the ear  560  (e.g., such as an ear canal) and include one or more other portions that are positioned outside of the ear  560 . 
     As described in greater detail below with respect to  FIGS. 6A-11 , the portions of the wearable audio device  500  positioned outside of the ear  560  may facilitate on-device control of the wearable audio device  500 . In this regard,  FIG. 5  shows a hand  570  proximate to the wearable audio device  500 . The hand  570  may form various gestures along the wearable audio device  500  (e.g., a first gesture, a second gesture) which may be detected by one or more input devices of the wearable audio device  500 . The gestures may be movements of the hand  570 ; and as such, the one or more input devices may detect a direction of the gesture input along, for example, an x-axis, a y-axis, and/or a z-axis. The hand  570  may also manipulate one or more structures of the wearable audio device  500  (such as a first or second manipulation of a tactile structure) which may also be detected by one or more input devices of the wearable audio device  500 . In either case, the wearable audio device  500  may detect the input from the hand  570 , or other object or body portion of the user  550 , and control an output of the wearable audio device  500 , such as controlling an audio output of a speaker. 
       FIG. 6A  depicts a sample wearable audio device  600 . The wearable audio device  600  may be substantially analogous to the wearable audio devices described herein. The wearable audio device  600  may therefore include similar components and/or perform similar functions of other wearable audio devices described herein, including an enclosure  610 , a main unit  614 , a stem  618 , a sealing component  622 , and a conformable surface  624 , redundant explanation of which is omitted here for clarity. 
     The wearable audio device  600  shown in  FIG. 6A  includes a touch-sensitive region  630  that may be defined along substantially any exterior surface of the enclosure  610 . For purposes of illustration, the touch-sensitive region  630  is defined on the exterior surface of the main unit  614 . In other embodiments, the touch-sensitive region  630  may be defined on other portions of the main unit  614  and/or the stem  618  (e.g., as described below with respect to  FIG. 8 ). 
     The touch-sensitive region  630  may be configured to detect various types of input, including gesture inputs performed along (e.g., on or above) the enclosure  610 . For example, the wearable audio device  600  may include one or more sensors (such as any of the input devices  110  of  FIG. 1A ) that are positioned within, or partially within, the enclosure and configured to detect a direction of a first gesture input, a direction of a second gesture input, and so on performed along the touch-sensitive region  630 . A processing unit of the wearable audio device  600  may receive input corresponding to the detected gesture and control one or more functions of the wearable audio device  600  such as an audio output, as described herein. 
       FIG. 6B  depicts a cross-sectional view of the enclosure  614 , the touch-sensitive region  630 , and the sensor  628  of the wearable audio device  600  of  FIG. 6A , taken along line C-C of  FIG. 6A . As shown in  FIG. 6B , the touch-sensitive region  630  may form part of an exterior wall or surface of the main unit  614  of the enclosure  610 . Positioned within an interior  611  of the main unit  614  is a sensor  628 . The sensor  628  may be substantially any of the sensors described with respect to the input devices  110  of  FIG. 1A . For example, the sensor  628  may be capacitive-based and configured to detect a change in capacitance between an electrode and a user and/or other object that approaches the main unit  614  at the touch-sensitive region  630 . Other possible sensors include optical sensors, which may detect change in an intensity of light along the input region  630  and/or otherwise detect optical changes (including pattern recognition, such as where the sensor  628  is a camera) that may correspond to input received at the wearable audio device  600 . 
     in some embodiments, the sensor  628  may be a substantially non-contact-based sensor. For example, the sensor  628  may be concealed or camouflaged within the main unit  614  and may be actuated based on proximity of a user or object, rather than physical contact with the sensor. In other cases, the sensor  628  may be, or form, a component of a contact-based switch or other mechanism that is actuated by the physical contact from a user. For example, the sensor  628  may be a collapsible dome (as shown in  FIG. 9 ), or other structure that includes electrical contacts that close in response to input or deformation on the enclosure  610 . 
     In the embodiment of  FIG. 6B , the enclosure  610  includes a tactile structure  634 . The tactile structure  634  may be any series or group of tactile features, ridges, bumps, grooves, discontinuities, and so on that may be tactilely distinguishable from an adjoining smooth or uninterrupted surface of the enclosure  610 . The tactile structure  634  may be a textured surface used to indicate the presence of input functionality along the enclosure  610  of the wearable audio device  600 . In this regard, the touch-sensitive region  630  may be defined on the tactile structure  634 ; however, this is not required. 
     The sensor  628  may detect various physical manipulations of the tactile structure  634 . For example, the sensor  628  may detect a first manipulation of the tactile structure  634 , a second manipulation of the tactile structure  634 , and so forth and provide signals to an associated processing unit corresponding to the different manipulations. For example, the first manipulation may be a finger moving on the tactile structure  634  in a first direction and the second manipulation may be a finger moving on the tactile structure  634  in a second, different direction. In other cases, the manipulations may be one or more of a squeeze, a roll, a press, a jog, and so on. In one sample embodiment, as described in greater detail below, the tactile structure  634  may be a portion of a stem or other feature of the wearable audio device  600 , and the sensor  628  may detect a corresponding manipulation. 
       FIG. 7  depicts a wearable audio device  700 . The wearable audio device  700  may be substantially analogous to other embodiments described herein. The wearable audio device  700  may therefore include similar components and/or perform similar functions of other wearable audio device described herein, including an enclosure  710 , a main unit  714 , a stem  718 , a sealing component  722 , and a conformable surface  724 , redundant explanation of which is omitted here for clarity. 
     The wearable audio device  700  shown in  FIG. 7  may include multiple touch-sensitive regions, such a first touch-sensitive region  730   a  and a second touch-sensitive region  730   b . Each of the first touch-sensitive region  730   a  and the second touch-sensitive region  730   b  may be substantially analogous to the touch-sensitive region  630  described above with respect to  FIGS. 6A and 6B . For example, each of the first touch-sensitive region  730   a  and the second touch-sensitive region  730  may be associated with one or more (or a common) sensor of the wearable audio device  700  that is configured to detect various gestures or manipulations performed along the enclosure  710 . Redundant explanation of these components is omitted here for clarity. 
     The multiple touch-sensitive regions of  FIG. 7  may be used to detect various different types of input that may be used to control different functions of the wearable audio device  700 . For example, the first touch-sensitive region  730   a  may be associated with a first function of the wearable audio device  700  (e.g., such as a volume up function) and the second touch-sensitive region  730   b  may be associated with a second function of the wearable audio device  700  (e.g., such as a volume down function). The wearable audio device  700  may detect input at a particular touch-sensitive region and perform the associated function, thereby allowing the wearable audio device  700  to have multiple, distinct buttons defined on the surface. The functions may be programmable or otherwise customizable by the user, such that multiple different functions may be executed by the wearable audio device  700 . This may be at least partially based on an operational context (such as that provided by the context module  175  of  FIG. 1B ), such as associating the touch-sensitive region with various different audio controls when the wearable audio device  700  is playing back an audio track, associating the touch-sensitive regions with various telecommunication controls when the wearable audio device  700  is handling a cellular call, and so on. 
     While the first touch-sensitive region  730   a  and the second touch-sensitive region  730   b  are shown as being defined on a substantially smooth exterior surface of the main unit  714 , it will be appreciated that the multiple touch-sensitive regions may be defined on substantially any exterior surface of the enclosure  710 . Some embodiments include touch-sensitive regions on both the main unit  714  and the stem  718  and/or multiple touch-sensitive regions on the stem  718  (e.g., as shown in  FIG. 8 ). Further, it will be appreciated that each of the first touch-sensitive region  730   a  and the second touch-sensitive region  730   b  may include distinct tactile features or structures, such as structures that each produce a distinct tactile output when contacted. As such, the distinct tactile outputs may indicate both the presence of input functionality along the enclosure  710  and the presence of distinct input functionalities as between the respective touch-sensitive regions. 
       FIG. 8  depicts a wearable audio device  800  that is substantially analogous to the wearable audio devices described herein, in some respects. The wearable audio device  800  may therefore include similar components and/or perform similar functions of other wearable audio devices described herein, including an enclosure  810 , a main unit  814 , a stem  818 , a sealing component  822 , and a conformable surface  824 , redundant explanation of which is omitted here for clarity. 
     The wearable audio device  800  shown in  FIG. 8  may include multiple touch-sensitive regions, such as a first touch-sensitive region  830   a  and a second touch-sensitive region  830   b . Each of the first touch-sensitive region  830   a  and the second touch-sensitive region  830   b  may be substantially analogous to the touch-sensitive region  630  described above with respect to  FIGS. 6A and 6B . For example, each of the first touch-sensitive region  830   a  and the second touch-sensitive region  830   b  may be associated with one or more (or a common) sensors of the wearable audio device  800  that are configured to detect various gestures or manipulations performed on the enclosure  810 . Redundant explanation of these components is omitted here for clarity. 
     The multiple touch-sensitive regions of the wearable audio device  800  may be defined on a portion of the stem  818  of the enclosure  810 . For example, as shown in  FIG. 8 , the first touch-sensitive region  830   a  may be defined on an end of the stem  818  and the second touch-second sensitive region  830   b  may be defined on the same end of the stem  818  opposite the first touch-sensitive region  830   a.    
     The arrangement of the first touch-sensitive region  830   a  and the second touch-sensitive region  830   b  on the stem  818  may allow the stem  818  to receive various types of input. For example, the first touch-sensitive region  830   a  and the second touch-sensitive region  830   b  may cooperate to detect a squeeze, pinch, pull, press, and/or other manipulation of the stem  818 . Continuing the example, the first touch-sensitive region  830   a  and the second touch-sensitive region  830   b  may each detect a touch that corresponds to a user contacting the stem  818  at the opposing sides. Upon a detection of the touch at each of the regions, a processing unit may control one or more functions of the wearable audio device  600 , such as controlling an audio playback function, activate a voice command mode, and so on. 
     In some cases, the stem  818  may be or otherwise define a tactile structure. For example, the stem  818  may be a deformable structure that elastically bends, twists, and so on when contacted by a user. As such, the first touch-sensitive region  830   a  and the second touch-sensitive region  830   b  may cooperate to detect physical manipulations of the stem  818 . This may include, in certain embodiments, a first manipulation of the stem (e.g., such as a twist of the stem  818  in a first direction), a second manipulation of the stem (e.g., such as a twist of the stem  818  in a second, opposing direction), among various other types of physical manipulations. 
       FIG. 9  depicts a wearable audio device  900  that may be substantially analogous in some respects to the wearable audio devices described herein. The wearable audio device  900  may therefore include similar components and/or perform similar functions of other wearable audio devices described herein, including an enclosure  910 , a main unit  914 , a stem  918 , a sealing component  922 , and a conformable surface  924 , redundant explanation of which is omitted here for clarity. 
     The wearable audio device  900  shown in  FIG. 9  may include one or more tactile structures positioned along an exterior of the enclosure  910 , such as tactile structure  940 . Tactile structure  940  may be a component of a mechanical switch or button that is configured to detect various types of input. For example, the tactile structure  940  may be a collapsible dome that buckles when pressed by a user. The collapsible dome may be a multi-input device, such that different signals are provided as a user presses into the dome (e.g., a first signal for a first manipulation or press of the dome, and a second signal for a second manipulation or press of the dome, and so on). In this regard, the tactile structure  940  may provide haptic feedback in response to the first manipulation and/or the second manipulation and close a corresponding switch or otherwise provide a signal corresponding to the respective manipulation. A processing unit may receive the provided signals and control a corresponding function of the wearable audio device  900 , such as controlling an audio output of the wearable audio device  900 . 
       FIG. 10  depicts a wearable audio device  1000 . The wearable audio device  1000  may be substantially analogous to the wearable audio devices described herein. The wearable audio device  1000  may therefore include similar components and/or perform similar functions of other wearable audio devices described herein, including an enclosure  1010 , a main unit  1014 , a stem  1018 , a sealing component  1022 , and a conformable surface  1024 , redundant explanation of which is omitted here for clarity. 
     The wearable audio device  1000  may include one or more tactile structures positioned along an exterior of the enclosure  1010 , such as the tactile structure  1040 . The tactile structure  1040  may be a component of a mechanical switch or button that is configured to detect various types of input. For example, the tactile structure  1040  may be a wheel that rotates when manipulated by a user. As shown in  FIG. 10 , the wheel may be positioned on or extend through a surface of the main unit  1014 ; however, in other embodiments, the wheel may be positioned on other surfaces, including on a surface of the stem  1018 . The wheel may be a multi-input device, such that various different signals are provided as a user causes the wheel to rotate (e.g., a first signal for a first rotation of the wheel and a second signal for a second rotation of the wheel, and so on). A processing unit may receive the provided signals and control a corresponding function of the wearable audio device  1000 , such as controlling an audio output of the wearable audio device  1000 . 
     Rotation may be detected using various techniques, such as using one or more of the input devices  110  described above with respect to  FIG. 1A . For example, one or more optical sensors positioned within the wearable audio device  1000  may detect rotation of the wheel using reflected light. In other cases, mechanical devices may be used, which may detect the rotation of the wheel using electrical, magnetic, or physical contacts disposed within the wearable audio device  1000 . The tactile structure  1040  may also provide haptic feedback in response to the rotation. This may be a resistive force that opposes rotational input. Additionally or alternatively, the tactile structure  1040  may produce an audible click. 
       FIG. 11  depicts a wearable audio device  1100 . The wearable audio device  1100  may be substantially analogous to the wearable audio devices described herein. The wearable audio device  1100  may therefore include similar components and/or perform similar functions of other wearable audio device described herein, including an enclosure  1110 , a main unit  1114 , a stem  1118 , a sealing component  1122 , and a conformable surface  1124 , redundant explanation of which is omitted here for clarity. 
     The wearable audio device  1100  shown in  FIG. 11  may include one or more tactile structures positioned along an exterior of the enclosure  1110 , such as the tactile structure  1140 . The tactile structure  1140  may be a component of a mechanical switch or button that is configured to detect various types of input. For example, the tactile structure  1140  may be a rotatable portion of the stem  1118  that is configured to rotate when manipulated by a user. As shown in  FIG. 11 , the rotatable portion may be positioned on an end of the stem  1118 ; however, in other embodiments, the rotatable portion may be positioned on other surfaces or features, including features of the main unit  1114 . The rotatable portion may be a multi-input device, such that various different signals are provided as a user causes the rotatable portion to rotate (e.g., a first signal for a first rotation of the rotatable portion and a second signal for a second rotation of the rotatable portion, and so on). A processing unit may receive the provided signals and control a corresponding function of the wearable audio device  1100 , such as controlling an audio output of the wearable audio device  1100 . 
     The rotation may be detected using various techniques, using one or more of the input devices  110  described above with respect to  FIG. 1A . For example, one or more optical sensors positioned within the wearable audio device  1100  may detect rotation of the rotatable portion using reflected light. In other cases, mechanical rotary detection devices may be used, which may detect the rotation of the rotatable portion using electrical contacts disposed within the wearable audio device  1100 . The tactile structure  1140  may also be configured to provide haptic feedback in response to the rotation. This may be a resistive force that opposes rotational input. Additionally or alternatively, the tactile structure  1040  may produce an audible click. 
       FIG. 12  depicts an example case  1200 . The case  1200  may generally be configured to receive one or more wearable audio devices, such as the first wearable audio device  1204   a  and the second wearable audio device  1204   b  shown in  FIG. 12 . In this regard, the case  1200  may be used to store and protect the first wearable audio device  1204   a  and the second wearable audio device  1204   b  when not in use. 
     For purposes of illustration, the case  1200  is shown as having an enclosure  1208 . The enclosure  1208  includes an upper portion  1208   a  and a lower portion  1208   b . The upper portion  1208   a  may pivot relative to the lower portion  1208   b , which may open the case  1200 . Defined within a least the lower portion  1208   b  may be one or more receiving features  1212 . The receiving feature  1212  may be configured to receive respective ones of the first wearable audio device  1204   a  and the second wearable audio device  1204   b . For example, in some embodiments, the receiving features  1212  may be contoured to a matching shape of the audio devices, which may allow the devices to be supported or snuggly received within the enclosure  1208 . The receiving features  1212  may also include various electrical connectors, terminals, adaptors, and so on that may electrically recharge wearable audio devices that are received by the receiving features  1212 . 
     The case  1200  may also function as a companion device to the wearable audio devices described herein, such as the first wearable audio device  1204   a  and/or the second wearable audio device  1204   b  shown in  FIG. 12 .

     In the embodiment of  FIG. 12 , the case  1200  may be configured to detect input, such as a gesture performed along an exterior of the enclosure  1208 . For example, as shown in  FIG. 12 , the lower portion  1208   b  may include a touch-sensitive region  1216 . One or more sensors, such as substantially any of the sensors of the input device  110  of  FIG. 1A , may be positioned within the enclosure  1208  and configured to detect the input at the touch-sensitive region  1216 . In some cases, the touch-sensitive region  1216  may be defined at a tactile structure or textured surface of the enclosure  1208  and the sensors within the case may be configured to detect various manipulations of the tactile structure. The sensor may detect the gesture, manipulation, or other input and provide a corresponding signal to, for example, a processing unit of the case  1200  and/or the wearable audio devices  1204   a ,  1204   b . The processing unit may receive the provided signals and control a corresponding function of the wearable audio devices  1204   a ,  1204   b , such as controlling an audio output of the wearable audio devices  1204   a ,  1204   b , among other functions.

     As shown in  FIG. 16 , the electronic device  1604  may include a processing unit or element  1608  operatively connected to computer memory  1612  and computer-readable media  1616 . The processing unit  1608  may be operatively connected to the memory  1612  and computer-readable media  1616  components via an electronic bus or bridge (e.g., such as system bus  1610 ). The processing unit  1608  may include one or more computer processors or microcontrollers that are configured to perform operations in response to computer-readable instructions. The processing unit  1608  may be a central processing unit of the stylus. Additionally or alternatively, the processing unit  1608  may be other processors within the device including application specific integrated chips (ASIC) and other microcontroller devices. 
     The memory  1612  may include a variety of types of non-transitory computer-readable storage media, including, for example, read access memory (RAM), read-only memory (ROM), erasable programmable memory (e.g., EPROM and EEPROM), or flash memory.

     In this example, the processing unit  1608  is operable to read computer-readable instructions stored on the memory  1612  and/or computer-readable media  1616 . The computer-readable instructions may adapt the processing unit  1608  to perform the operations or functions described above with respect to  FIGS. 1A-15 . The computer-readable instructions may be provided as a computer-program product, software application, or the like.

The battery  1624 , via power management circuitry, may be configured to receive power from an external source, such as an AC power outlet or interconnected computing device. The battery  1624  may store received power so that the electronic device  1604  may operate without connection to an external power source for an extended period of time, which may range from several hours to several days. 
     The electronic device  1604  may also include one or more sensors  1640  that may be used to detect a touch and/or force input, environmental condition, orientation, position, or some other aspect of the electronic device  1604 .
