     DETAILED DESCRIPTION OF THE DISCLOSURE 
     Earphone assemblies with multiple subassembly housings are provided and described with reference to  FIGS. 1-16H . 
     Any suitable type of earbud subassembly or earbud subassemblies may be provided by an earphone assembly of the disclosure. For example, an earphone assembly may include one or more occluding earbuds or earphones configured to be at least partially inserted into an ear canal of a user (e.g., an in-ear headphone or in-ear monitor or canalphone assembly) (see, e.g., earbud subassembly  200  and/or earbud subassembly  300  of earphone assembly  100  of  FIGS. 1-5 ). Alternatively, an earphone assembly may include one or more non-occluding earbuds or earphones configured not to be at least partially inserted into the ear canal of the user but that may fit directly in the outer ear of the user (e.g., within a concha of the ear) and face the ear canal. A wingtip (not shown) that may be operative to anchor to a portion of a user&#39;s ear (e.g., the anti-helix crus of the ear) may be removably coupled to an earbud subassembly of an earphone assembly, such that the wingtip may only be used when desired and/or such that different wingtips of different sizes may be interchangeably coupled to an earbud of an earphone assembly based on the size of the user&#39;s ear. Alternatively, such a wingtip may be an integral part of an earphone assembly, such as a wingtip that is molded to or otherwise fixed to an earbud or other portion of the earphone assembly. 
     As shown in  FIGS. 1-1F , an earphone assembly  100  may include a first earbud subassembly  200 , a second earbud subassembly  300 , a power supply subassembly  500 , a logic subassembly  600 , an input subassembly  700 , and various cable subassemblies that may electrically couple the other subassemblies of earphone assembly  100 , such as a first cable subassembly  110  that may electrically couple earbud subassembly  200  with input subassembly  700 , a second cable subassembly  120  that may electrically couple earbud subassembly  300  with power supply subassembly  500 , a third cable subassembly  130  that may electrically couple input subassembly  700  with logic subassembly  600 , and a fourth cable subassembly  140  that may electrically couple power supply subassembly  500  with logic subassembly  600 . Each one of first earbud subassembly  200  and second earbud subassembly  300  may be operative to receive audio data electrical signals (e.g., from cable subassembly  110  and cable subassembly  120 , respectively), to convert or transduce the received electrical signals into corresponding sound waves, and to emit the sound waves towards an eardrum of a user wearing the earbud subassembly. First earbud subassembly  200  and second earbud subassembly  300  may be substantially the same in function, shape, and/or size, but may be mirror images of one another, such that each may be configured for comfortable use within a respective one of a user&#39;s left and right ears, where, for example, first earbud subassembly  200  may be configured for use in a user&#39;s left ear and second earbud subassembly  300  may be configured for use in a user&#39;s right ear, while the various cable subassemblies  110 ,  120 ,  130 , and  140  in combination with subassemblies  500 ,  600 , and  700  may together physically couple earbud subassemblies  200  and  300  and may together be worn around a backside of a neck of the user or under the chin of the user or over the head of the user or in any other suitable fashion when subassemblies  200  and  300  are worn by the user&#39;s ears. 
     Power supply or battery subassembly  500  may include a battery or any other suitable power supply operative to receive and store power that may then be used to power various other subassemblies of assembly  100 , where such power may be shared with one or more of subassemblies  200 ,  300 ,  600 , and/or  700  via one or more of cable subassemblies  110 ,  120 ,  130 , and/or  140 . The power supply may be rechargeable via a charging port of assembly  100  (e.g., a charging port of power supply subassembly  500  and/or of logic subassembly  600 ) and/or may be replaceable. Power supply subassembly  500  may include a power button that may be used to turn assembly  100  on and off. Logic or main logic board (“MLB”) subassembly  600  may include any suitable components for controlling the functionality of assembly  100 , such as, but not limited to, a processor component, a memory component, a wireless communication component for receiving audio data information from a media player or radio source, a wired connector for connecting via a cable with a media player (not shown), a media player application if no remote media source is to be used, a charging port for the power supply of power supply assembly  500 , and/or the like, each of which may be at least partially provided on an MLB. Input or user communication box subassembly  700  may include any suitable components for receiving user input commands for controlling assembly  100 , such as, but not limited to, a microphone, one or more buttons that may be configured to receive user input for controlling volume and/or media selection, and/or the like. In some embodiments, assembly  100  may include other components not combined or included in those shown or several instances of the components shown. 
     As shown in one or more of  FIGS. 2-5 , earbud subassembly (hereinafter “earbud”)  200  may include various components for receiving and transducing audio data electrical signals into corresponding sound waves as well as various components for maintaining a functional position within a user&#39;s outer ear and emitting the sound waves towards an eardrum of a user when worn by the user in the functional position. For example, earbud  200  may include an eartip  210 , a front housing  230 , a sound emitting subassembly or driver or transducer  250 , a rear housing  270 , and a wingtip subassembly  400 . Front housing  230  and rear housing  270  may be operative to be coupled to one another to define an interior housing space within which at least a portion of sound emitting subassembly  250  may be held. An adhesive and/or mechanical snap-fit features and/or any other suitable coupling technique(s) may be used to hold front housing  230  and rear housing  270  together (e.g., to hold rear face  239  of front housing  230  to front face  271  of rear housing  270 ) and/or to hold sound emitting subassembly  250  to one or both of front housing  230  and rear housing  270 . Earbud  200  may include a transducer adhesive  293  that may be operative to adhere to both a front face  251  of sound emitting subassembly  250  and to a rear face of front housing  230 . Moreover, front housing  230  and rear housing  270  may be operative to communicatively couple a portion of front face  251  of sound emitting subassembly  250  to an inner eartip space  225  extending between a rear end opening  229  and a front end opening  221  of an inner eartip member  220  of eartip  210 . For example, when held between front housing  230  and rear housing  270 , an audio opening  252  provided through front face  251  of sound emitting subassembly  250  for emitting sound waves from sound emitting subassembly  250  (e.g., from a diaphragm and/or membrane  254  of subassembly  250  (see, e.g.,  FIG. 6 )) may be communicatively aligned with a sound axis S that may also be aligned with an inner nozzle space  245  extending between a rear end opening  249  and a front end opening  241  of a nozzle member  240  of front housing  230  and that also may be aligned with inner eartip space  225  of inner eartip member  220 , where such alignment may be operative to optimize treble response (e.g., such that sound may be emitted from audio opening  252 , along sound axis S, through a portion of the interior housing space that may be defined by front housing  230  and rear housing  270  when coupled to one another (e.g., a portion of a front chamber  253 ), and through inner nozzle space  245 ). One or more mating features  228  along an outer surface of inner eartip member  220  may be operative to removably or fixedly mate with one or more mating features  248  along an inner surface of nozzle member  240  for communicatively coupling inner eartip space  225  defined by inner eartip member  220  of eartip  210  with inner nozzle space  245  defined by nozzle member  240  of front housing  230 , such that sound waves emitted from sound emitting subassembly  250  (e.g., from audio opening  252 ) may be carried along a sound path (e.g., in the +S direction along sound axis S) through rear end opening  249  of nozzle member  240 , along both inner nozzle space  245  and inner eartip space  225 , and then out from front end opening  221  of inner eartip member  220  of eartip  210 . Nozzle member  240  may have any suitable geometry. For example, an internal cross-sectional diameter or dimension of front end opening  241  and/or of rear end opening  249  of nozzle member  240  may be configured to have any suitable magnitude, such as in a range between 2.21 millimeters and 4.10 millimeters or about 3.15 millimeters, while a length of nozzle member  240  between openings  241  and  249  may be configured to have any suitable magnitude, such as in a range between 3.36 millimeters and 6.24 millimeters or about 4.80 millimeters. Any suitable filter or mesh  291  may be provided along or across the sound path, such as over front end opening  241  of nozzle member  240 , for enabling sound to pass therethrough and out from eartip  210  while preventing debris (e.g., dust and/or liquids) to pass therethrough and into inner nozzle space  245 . 
     Eartip  210  may be operative to provide a comfortable fit for earbud  200  at least partially within an ear canal of a user and/or to form an acoustic seal between earbud  200  and the ear canal and/or to pass sound through the ear canal via front end opening  221  when earphone assembly  100  is worn by the user. For example, an external eartip structure  214  of eartip  210  may extend from a front end opening  211  (e.g., at front end opening  221  of inner eartip member  220 ) rearwards to a rear end opening  219  that may surround a portion of front housing  230  (e.g., nozzle member  240 ) to define an outer eartip space  215  between an internal surface of external eartip structure  214  and an external surface of inner eartip member  220 , such that external eartip structure  214  may be deformable to fit within any suitable portion of a user&#39;s ear, such as an ear canal for forming the acoustic seal between earbud  200  and the user&#39;s ear. A front vent opening  233  may be provided through front housing  230  for enabling pressure relief of a front chamber  253  that may be defined by a space between front face  251  of sound emitting subassembly  250  and a portion of front housing  230  and a portion of eartip  210  and that may channel sound emitted from audio opening  252  of sound emitting subassembly  250  through front end opening  211 / 221  of eartip  210  (e.g., front chamber  253  may be a portion of the interior housing space that may be defined by front housing  230  and rear housing  270  when coupled to one another). A rear face of front housing  230  may be coupled to front face  251  of sound emitting subassembly  250  about audio opening  252  (e.g., by transducer adhesive  293 ) to define a rear boundary of front chamber  253  along front face  251 , where that rear boundary may have any suitable geometry, such as a circular shape with a diameter having any suitable magnitude, such as in a range between 3.36 millimeters and 6.24 millimeters or about 4.80 millimeters, while a distance along axis S between that rear boundary and front end opening  241  of nozzle member  240  may have any suitable magnitude, such as in a range between 4.54 millimeters and 8.44 millimeters or about 6.49 millimeters. Front vent opening  233  may be positioned so as not be covered or otherwise blocked by external eartip structure  214  or any other portion of eartip  210  when earbud  200  is held by a user&#39;s ear, yet eartip structure  214  may be operative to obfuscate or hide at least a portion of opening  233  (e.g., in a shadow of structure  214  on front housing  230 ) for cosmetic purposes or the size of an external opening of opening  233  may not be easily viewable by the naked eye. A rear vent opening  237  may be provided through front housing  230  for enabling pressure relief of a rear chamber  257  that may be defined by a space between a side face  255  and/or a rear face  259  of sound emitting subassembly  250  and a portion of front housing  230  and a portion of rear housing  270 . Any suitable filter or mesh  292  may be provided along the pressure relief path of rear vent opening  237 , such as over opening  237  and against an internal surface of front housing  230  between front housing  230  and sound emitting subassembly  250 , for enabling sound or other suitable air to pass therethrough and out from rear chamber  257  via opening  237  while preventing debris (e.g., dust and/or liquids) to pass therethrough and into rear chamber  257 . 
     Rear housing  270  may include a cable opening  277  through which a portion of cable subassembly  110  may pass, such that an end of one or more conductors at an end of cable subassembly  110  (not shown) may be positioned within earbud  200  (e.g., within rear chamber  257  defined by rear housing  270 ) in order to be electrically coupled to one or more respective contacts of sound emitting subassembly  250 . For example, as shown, cable opening  277  may be provided at a bottom end of a cable external strain relief structure  276  of rear housing  270  that may extend from a side structure  274  of rear housing  270  extending between front face  271  and rear face  279  of rear housing  270 . Earbud  200  may also include an internal strain relief structure  294  that may be coupled to rear housing  270  for protecting at least a portion of the physical coupling between cable subassembly  110  and earbud  200  (e.g., to provide additional strain relief to that connection). A magnet  295  may be positioned against rear face  279  of rear housing  270  by any suitable mechanism(s), such as by an adhesive  296 , and/or by a rear plate  297  that may be coupled to rear face  279  of rear housing  270 . A complimentary magnet may be provided at a similar position on earbud  300 , such that the magnets may magnetically hold earbud  200  and earbud  300  together when they are not in use (e.g., when earbuds  200  and  300  are not positioned within a user&#39;s ears), which may prevent the cable subassemblies of earphone assembly  100  from becoming tangled and/or may keep earphone assembly  100  compact. As shown in  FIG. 3 , for example, an X-Y plane that may include rear plate  297  and/or rear face  279  of rear housing  270  may form a rear sound angle RSθ (e.g., acute angle) with sound axis S (e.g., the axis along which nozzle member  240  may extend), where such a rear sound angle RSθ may be any suitable angle, such as in a range between 47° and 87° or about 67°. In other embodiments, axis S may be perpendicular to rear face  279  such that rear sound angle RSθ may be 90°. 
     As shown in  FIGS. 2-5A , front housing  230  may include a front housing structure  234  that may extend rearwardly from rear end opening  249  of nozzle member  240  to rear face  239  of front housing  230 . Front housing structure  234  may include an exterior surface  235  and an opposite interior surface  236  that may define a portion of front chamber  253 , while front vent opening  233  may be provided by a passageway extending through structure  234 , including through both exterior surface  235  and interior surface  236 . As shown in  FIG. 5A , for example, front vent opening  233  may be provided by a passageway  238  including a first passageway portion  238   a  and a second passageway portion  238   b . In some embodiments, first passageway portion  238   a  may be provided by a notch or indentation into front housing structure  234  at exterior surface  235  to define an exterior opening  233   a  of front vent opening  233 , while second passageway portion  238   b  may be provided by any suitable hollow into front housing structure  234  at interior surface  236  to define an interior opening  233   b  of front vent opening  233 . First passageway portion  238   a  may be any suitable shape and size, such as cylindrical with a cross-sectional diameter or dimension FPD and a height FPH only partially through structure  234  towards interior surface  236 , while second passageway portion  238   b  may be any suitable shape and size, such as cylindrical with a cross-sectional or dimension SPD and a height SPH only partially through structure  234  towards exterior surface  235  that joins first passageway portion  238   a , and where each one of passageway portions  238   a  and  238   b  may be centered about a front vent axis F (e.g., each one of cross-sectional dimension FPD of portion  238   a  and cross-sectional dimension SPD of portion  238   b  may be perpendicular to and/or centered about axis F). 
     Each passageway portion may have any suitable geometry. For example, cross-sectional diameter or dimension FPD of first passageway portion  238   a  may be configured to have any suitable magnitude, such as in a range between 0.35 millimeters and 0.65 millimeters or about 0.50 millimeters, height FPH of first passageway portion  238   a  may be configured to have any suitable magnitude, such as in a range between 1.015 millimeters and 1.885 millimeters or about 1.450 millimeters, cross-sectional diameter or dimension SPD of second passageway portion  238   b  may be configured to have any suitable magnitude, such as in a range between 0.02 millimeters and 0.10 millimeters or about 0.05 millimeters (e.g., to prevent water entry but enable airflow through passageway portion  238   b ), and height SPH of second passageway portion  238   b  may be configured to have any suitable magnitude, such as in a range between 0.28 millimeters and 0.52 millimeters or about 0.40 millimeters. Passageway portions  238   a  and  238   b  may be formed in any suitable manner(s) for providing front vent opening  233 . For example, in some embodiments, first passageway portion  238   a  may be formed during a molding process for forming at least structure  234  if not also other portions or the entirety of front housing  230  (e.g., a molding process using polybutylene terephthalate (“PBT”) and/or polycarbonate (“PC”) and/or any other suitable thermoplastic polymer(s) for providing structure  234  and/or otherwise of front housing  230 ), while second passageway portion  238   b  may then be formed by laser drilling second passageway portion  238   b  through a remaining thickness SPH of structure  234 . While first passageway portion  238   a  may be shown provided through exterior surface  235  of structure  234  and while second passageway portion  238   b  may be shown provided through interior surface  236  of structure  234 , in other embodiments first passageway portion  238   a  may be provided through interior surface  236  of structure  234  while second passageway portion  238   b  may be provided through exterior surface  235  of structure  234 . Although only one second passageway portion  238   b  may be shown, multiple second passageway portions  238   b  may be provided through structure  234  at a single first passageway portion  238   a  (e.g., along a circular path that may mimic the cross-sectional shape of first passageway portion  238   a ), or multiple first passageway portions  238   a  may be provided at different portions of structure  234  and one or more second passageway portions  238   b  may be provided at each first passageway portion  238   a . Front vent opening  233  may be provided through structure  234  of front housing  230  for enabling pressure relief of front chamber  253  that may be defined by a space between front face  251  of sound emitting subassembly  250  and a portion of front housing  230  and a portion of eartip  210  and that may channel sound emitted from audio opening  252  of sound emitting subassembly  250  through front end opening  211 / 221  of eartip  210 . 
     As mentioned, front vent opening  233  may prevent pressure build up on the ear (e.g., ear drum) of the user during use of earbud  200  and/or may prevent certain distortion of certain components of sound emitting subassembly  250  (e.g., deformation of diaphragm and/or membrane  254  of subassembly  250  (see, e.g.,  FIG. 6 )) and/or generation of certain crackling sounds during use and/or when earbud  200  is positioned within or removed from the user&#39;s ear. Cross-sectional diameter or dimension SPD of second passageway portion  238   b  may be small enough to prevent water passing therethrough and/or to avoid negatively affecting the sound emitted by sound emitting subassembly  250  (e.g., such that deep bass sound waves (e.g., down to and/or below 20 hertz) may be perfectly reproduced for the user as if front vent opening  233  was not present). By providing second passageway portion  238   b  through a reduced thickness portion of structure  234  (e.g., due to first passageway portion  238   a ), the magnitude of height SPH of second passageway portion  238   b  may be reduced, which may tune the frequency response of earbud  200  accordingly. 
     Sound emitting subassembly  250  may provide any suitable transducer or driver that may be operative to receive audio data electrical signals (e.g., from cable subassembly  110 ), to convert or transduce the received electrical signals into corresponding sound waves, and to emit the sound waves (e.g., in the +S direction along sound axis S) towards an eardrum of a user wearing earbud subassembly  200 . As shown in  FIG. 6 , sound emitting subassembly  250  may include a flexible diaphragm or membrane  254  that may be coupled at an outer periphery to a frame  256   f  and may include a former at one or more intermediate positions with a moving coil  256   c  coupled thereto. A permanent magnet  256   m  may be positioned about moving coil  256   c , for example, using frame  256   f , at least one washer  256   w , and a t-yoke  256   y . The audio data electrical signals may be passed through coil  256   c  so as to generate an electromagnetic field that may produce and electromagnetic force that may be opposed by the main permanent magnetic field generated by permanent magnet  256   m  such that coil  256   c  may move membrane  254 , which may cause a disturbance in the air around membrane  254  for producing sound waves. At least some of these sound waves may be emitted through audio opening  252  that may be provided through a cover structure or front face  251 , which may also be coupled at an outer periphery to frame  256   f , and which may be operative to protect at least a portion of membrane  254 . Therefore, membrane  254  may be operative to move in a magnetic gap for vibrating and producing sound waves. Membrane  254  may be any suitable shape and size, but may be a thin, semi-rigid but flexible structure. In some particular embodiments, membrane  254  may be a laminate or other suitable combination of multiple layers or films of materials stacked on top of one another to provide a composite structure that may be operative to provide or otherwise enable the tonality desired for sound emitting subassembly  250  to generate a target sound. For example, membrane  254  may include a first layer of material including any suitable polyurethane (“PU”) (e.g., any suitable PU elastomer) and a second layer of material including any suitable polyarylate (“PAR”) (e.g., [-φ-C(CH3)2-φ-CO2-φ-CO2-]n, amorphous polyester of bisphenol-A with isophthalic and terephthalic acids, etc.). Either one of such a first layer and such a second layer may be a top-most layer of membrane  254  closest to cover  251  and/or where either one of such a first layer and such a second layer may be a bottom-most layer of membrane  254  closest to a driver space  256   s  within sound emitting subassembly  250  that may be covered at a rear end by a mesh  256   m . Membrane  254  may include one of each of such first and second layers or membrane may include multiple ones of one or each of such first and second layer types in any suitable stacking order. 
     Cable subassembly  140  may electrically couple power supply subassembly  500  with logic subassembly  600  and, in some embodiments, may be operative to maintain or hold or at least return to a curved shape (e.g., when no external forces are applied thereto (e.g., at least when no external forces are applied to assembly  100 )) such that cable subassembly  140  may be positioned to wrap around the back of a user&#39;s neck when earbuds  200  and  300  are worn in the user&#39;s ears.

As also shown, top power neckband joint component  522  may include a ring groove  524  that may be operative to receive and hold first locating ring  148   bm  of neckband subassembly  140  and/or a cover groove  525  that may be operative to receive and hold one or more portions of cover  148  proximate first cover end  148   b  (e.g., the portions of cover  148  about first locating ring  148   bm ), such that neckband subassembly  140  may be held at a particular position with respect to top power neckband joint component  522  that may facilitate the proper positioning of each conductor  142  in a respective conductor groove  521  (e.g., an adhesive (e.g., a high viscosity, ethyl-based instant adhesive) may be applied to the surface of top power neckband joint component  522  providing grooves  521 , groove  524 , and groove  525  for holding conductors  142 , ring  148   bm , and cover  148 , respectively). As also shown, top power neckband joint component  522  may include one or more bottom power neckband joint mating features  523  that may be used to align and mate with one or more respective features on bottom power neckband joint component  528  for coupling the two components together (e.g., as shown in  FIGS. 10C and 11C ). Moreover, as shown in  FIG. 10C , logic neckband joint  620  may be positioned about a second portion of cover  148  that may include second locating ring  148   rm  and/or second cover end  148   m  (e.g., second conductor end  142   m  of each conductor  142  and core end  144   m  of neckband subassembly  140  may be passed through logic neckband joint  620  such that second locating ring  148   rm  and/or second cover end  148   m  may be positioned within an interior space defined by logic neckband joint  620 ). While logic neckband joint  620  may be shown as a single unitary component, power neckband joint  520  may be provided as top power neckband joint component  522  and bottom power neckband joint component  528  such that unfettered access may be provided to each conductor groove  521  for enabling specific positioning of each conductor  142  proximate its conductor end  142   b  at power neckband joint  520  (e.g., due to a limited length (e.g., 3 millimeters) of each conductor  142  between its conductor end  142   b  and its conductor portion retained by its respective conductor groove  521  (e.g., a distance between power neckband joint  520  and PCB  530  to which each conductor end  142   b  may be electrically coupled (e.g., via hot bar soldering) may be much shorter than the distance between logic neckband joint  620  and MLB  630  at which each conductor end  142   m  may be electrically coupled, such that specific positioning of each conductor end  142   b  with respect to power neckband joint  520  ought to be accomplished within power neckband joint  520 )). 
     Next, as shown in  FIGS. 10D and 11D , power neckband innermold portion  590  may be positioned about a portion of top power neckband joint component  522  and about a portion of bottom power neckband joint component  528  of power neckband joint  520 . For example, power neckband innermold portion  590  may be molded (e.g., using any suitable TPE(s)) about power neckband joint  520  to cover any seam formed between top power neckband joint component  522  and bottom power neckband joint component  528 , such that power neckband innermold portion  590  may be operative to seal about top power neckband joint component  522  and bottom power neckband joint component  528  (e.g., to prevent mold material of power neckband housing portion  510  from flowing into the space defined by power neckband joint components  522  and  528  within which sensitive portions of conductors  142  may exist or through which sensitive portions of conductors  142  may be accessed). Then, as shown in  FIGS. 10E, 10F, and 11E , power neckband housing portion  510  may be positioned about a portion of power neckband joint  520  and/or about a portion of power neckband innermold portion  590  and/or about a portion of neckband subassembly  140  to provide a cosmetic and/or protective shell about portions of the coupling joint between neckband subassembly  140  and power supply subassembly  500  (e.g., any suitable overmolding process using any suitable materials (e.g., silicone) may be used to provide power neckband housing portion  510 ). Similarly, as also shown, logic neckband housing portion  610  may be positioned about a portion of logic neckband joint  620  and/or about a portion of neckband subassembly  140  to provide a cosmetic and/or protective shell about portions of the coupling joint between neckband subassembly  140  and logic subassembly  600  (e.g., any suitable overmolding process using any suitable materials (e.g., silicone) may be used to provide logic neckband housing portion  610 ). It is to be noted that certain portions of bottom power neckband joint component  528  and core component  144  are not shown in  FIGS. 11C-11E . 
     As shown in  FIG. 12A , core component  144  may extend between ends  144   b  and  144   m  through the entirety of neckband subassembly  140  as well as through power neckband housing portion  510  and power neckband joint  520  and power neckband innermold portion  590  of power supply subassembly  500  as well as through logic neckband housing portion  610  and logic neckband joint  620  of logic subassembly  600 , where a rigid linear length of core component  144  may maintain neckband subassembly  140  in a linear shape. As shown, core component  144  proximate core end  144   b  may be supported by or at least extend along a top surface of an extension arm  529  of bottom power neckband joint component  528 . Next, as shown in  FIG. 12B , core component  144  may be removed from earphone assembly  100  (e.g., from neckband subassembly  140  and power supply subassembly  500  and logic subassembly  600 , in any suitable direction (e.g., by pulling core end  144   m  away from logic subassembly  600  such that core end  144   b  may eventually exit logic neckband joint  620  of logic subassembly  600 , or by pulling core end  144   b  away from power supply subassembly  500  such that core end  144   m  may eventually exit power neckband joint  520  of power supply subassembly  500 )). Once core component  144  has been removed from neckband subassembly  140 , neckband subassembly  140  may later include a memory component  146  that may be positioned between or otherwise alongside conductors  142  within cover  148 , such as in replacement of core component  144 , and may extend between a first memory end  146   b  proximate first conductor ends  142   b  and a second memory end  146   m  proximate second conductor ends  142   m . Memory component  146  may be made of any suitable material, such as one or two or more nitinol steel wires, and may be any suitable shape, such as a curved shape to define the curved shape of final neckband subassembly  140 . The defined shape of memory component  146  may be formed using any suitable process and/or materials such that the shape may be resilient, whereby memory component  146  may be operative to return to the shape absent any external forces (e.g., any external forces above a certain magnitude) being applied thereto (e.g., to enable memory component  146  to deform out of the curved shape when a user applies a strong force to memory component  146  but then to return to the curved shape when a strong force is removed, such that memory component  146  may be operative to hold neckband subassembly  140  in the curved shape of  FIG. 1 ). 
     As shown in  FIG. 12C , memory component  146  may be introduced into assembly  100  in at least a portion of a space previously occupied by core component  144  (e.g., the same space within neckband subassembly  140  and at least a portion of the same space within power supply subassembly  500  and/or at least a portion of the same space within logic subassembly  600 ). As shown, second end  146   m  of memory component  146  may be inserted into power neckband joint  520  through an opening to the space previously occupied by core component  144 . This opening may be accessed by second end  146   m  of memory component  146  from a bottom surface of extension arm  529  of bottom power neckband joint component  528  (e.g., not from along the same top surface of extension arm  529  along which core component  144  extended (see, e.g.,  FIG. 12A )). 
     Once second end  146   m  of memory component  146  has been moved through neckband subassembly  140  and out from logic neckband joint  620  of logic subassembly  600 , first end  146   b  of memory component  146  may be fixed to or otherwise held against at least a portion of power supply subassembly  500  while second end  146   m  of memory component  146  may be fixed to or otherwise held against at least a portion of logic subassembly  600  (e.g., memory component  146  may be deformed out from its curved shape into any other suitable shape (e.g., a straight shape) in any suitable manner, such as by applying any suitable any external forces above a certain magnitude to memory component  146  (e.g., by applying a pulling force at opposite ends  146   b  and  146   m  of memory component  146 ), while memory component  146  may be introduced into assembly  100  in at least a portion of a space previously occupied by core component  144 , where the deformed shape may be easier to introduce than the curved shape). For example, as shown in  FIG. 12D , a portion of memory component  146  may be bent at any suitable angle (e.g., 90°) proximate to second end  146   m  for defining a bend region  146   mn  (e.g., along each of the two illustrated memory wires of memory component  146 ), such that at least a portion of a memory component section  146   mp  extending between bend region  146   mn  and second end  146   m  may be operative to extend along and against a surface  620   s  of logic neckband joint  620  that may face away from the direction in which memory component  146  travels through logic neckband joint  620  towards neckband subassembly  140 . As shown, surface  620   s  may also define or be adjacent another surface of logic neckband joint  620  defining an opening through which conductors  142  may extend out from logic neckband joint  620 . A glue (e.g., any suitable UV curing glue) or any other suitable adhesive component (not shown) may be applied to at least a portion of memory component section  146   mp  and/or to at least a portion of surface  620   s  to help fix memory component  146  to logic neckband joint  620 . Any other suitable portions of any suitable other components of logic subassembly  600  may then be coupled to logic neckband housing portion  610  and/or logic neckband joint  620  for completing the assembly of logic subassembly  600  (e.g., as described with respect to  FIG. 8 ). In some embodiments, certain couplings between component features of logic subassembly  600  may also be operative to retain memory component  146  to logic neckband joint  620  or otherwise to logic subassembly  600 . 
     Additionally, as also shown in  FIG. 12D , a portion of memory component  146  may be bent at any suitable angle (e.g., 90°) proximate to first end  146   b  for defining a bend region  146   bn  (e.g., along each of the two illustrated memory wires of memory component  146 ), such that at least a portion of a memory component section  146   bp  extending between bend region  146   bn  and first end  146   b  may be operative to extend along and against a surface  520   s  of power neckband joint  520  that may face away from the direction in which memory component  146  travels through power neckband joint  520  towards neckband subassembly  140 . As shown, surface  520   s  may be defined by a protrusion  529   p  that may be extending out away from a bottom surface of extension arm  529  of bottom power neckband joint component  528  and another portion of memory component section  146   bp  may extend along and/or against a portion of that bottom surface of extension arm  529 . Neither protrusion  529   p  nor the bottom surface of extension arm  529  may define a surface of power neckband joint  520  defining an opening through which conductors  142  may extend out from power neckband joint  520 . Instead, conductors  142  may extend along or adjacent to a portion of a top surface of extension arm  529  of power neckband joint  520 . A glue (e.g., any suitable UV curing glue) or any other suitable adhesive component (not shown) may be applied to at least a portion of memory component section  146   bp  and/or to at least a portion of surface  520   s  to help fix memory component  146  to power neckband joint  520 . As also shown, a second surface  520   s ′ of a second protrusion  529   p ′ that may be extending out away from the bottom surface of extension arm  529  of bottom power neckband joint component  528  may also be used to retain memory component section  146   bp  or at least to prevent memory component section  146   bp  from moving further away from neckband subassembly  140 . 
     Any other suitable portions of any suitable other components of power supply subassembly  500  may then be coupled to power neckband housing portion  510  and/or power neckband joint  520  for completing the assembly of power supply subassembly  500  (e.g., as described with respect to  FIG. 9 ). In some embodiments, certain couplings between component features of power supply subassembly  500  may also be operative to retain memory component  146  to power neckband joint  520  or otherwise to power supply subassembly  500 . As shown in  FIGS. 13A and 13A ′, prior to button carrier  540  being coupled to PCB  530 , one, some, or each one of conductors  142  at or proximate to conductor end  142   b  may be electrically coupled (e.g., using any suitable technique, such as hot bar soldering) to a respective contact  532  of PCB  530  (e.g., each contact  532  may be provided by a top surface  531  of PCB  530 ), while a first projection  527   a  extending from a surface of power neckband joint  520  (e.g., from a top surface of top power neckband joint component  522 ) may extend through a slot  537   a  in PCB  530  for properly aligning and/or holding PCB  530  in position with respect to power neckband joint  520 . Moreover, as also shown in  FIGS. 13A and 13A ′, prior to button carrier  540  being coupled to PCB  530 , a switch component  534  (e.g., any suitable tactile switch component) may be provided on PCB  530 , where switch component  534  may be coupled to a bottom surface  533  of PCB  530  and may include a switch element  535  extending upwards towards button carrier  540 , where a lower surface of PCB  530  may be positioned to rest on and/or be fitted against and/or about a surface  520   ss  of a raised subprojection  529   sp  of projection  529   p ′ of bottom power neckband joint component  528  of power neckband joint  520  and/or a leading surface of PCB  530  may be positioned to push against memory component section  146   bp  towards neckband subassembly  140  (see, e.g.,  FIGS. 12D, 13A ′,  14 L, and  14 M). Moreover, as also shown in  FIGS. 13A and 13A ′, prior to button carrier  540  being coupled to PCB  530 , one or more conductors or contacts of battery  550  may be electrically coupled (e.g., using any suitable technique, such as hot bar soldering) to a respective battery contact of PCB  530  (e.g., each battery contact may be provided by top surface  531  of PCB  530 ). Moreover, as also shown in  FIGS. 13A and 13A ′, prior to button carrier  540  being coupled to PCB  530 , battery bracket  560  and power housing strain relief portion  570  may be positioned about and/or against batter  550 , where a bracket arm  562  of battery bracket  560  may include a free end extending away from battery  550  towards power neckband joint  520 , such that bracket arm  562  may rest on or extend over a top of switch element  535  of switch component  534 , and where a bracket arm  564  of battery bracket  560  may include a free end extending away from battery  550  towards power neckband joint  520 , such that a slot  567   b  of bracket arm  564  may receive a second projection  527   b  extending from a surface of power neckband joint  520  (e.g., from a bottom surface of bottom power neckband joint component  528 ) and/or such that a hole  567   c  through bracket arm  564  may receive a third projection  527   c  extending from a surface of power neckband joint  520  (e.g., from a bottom surface of bottom power neckband joint component  528 ) for properly aligning and/or holding battery bracket  560  in position with respect to power neckband joint  520 . 
     Next, as shown in  FIGS. 13B and 13B ′, button carrier  540  may be moved downward into place about PCB  530 , where at least a portion of top portion  541  of button carrier  540  may rest on power neckband joint  520 , and/or where a front wing  542  of button carrier  540  may extend from top portion  541  of button carrier  540  and along and adjacent to a top surface of top power neckband joint component  522 , and/or where a back wing  548  of button carrier  540  may extend from top portion  541  of button carrier  540  and along and adjacent to a back surface of back power neckband joint component  528 . As shown in  FIG. 13B , for example, front wing  542  may include a first slot  542   p  that may receive a portion of a protrusion  527   b  that may be extending out away from a surface of power neckband joint  520  for properly aligning and/or holding button carrier  540  in position with respect to power neckband joint  520 . As shown in  FIG. 13B ′, for example, back wing  548  may include a first slot  548   p  that may receive a portion of protrusion  529   p  that may be extending out away from a bottom surface of extension arm  529  of bottom power neckband joint component  528  of power neckband joint  520 , and/or back wing  548  may include a second slot  548   sp  that may receive a portion of raised subprojection  529   sp  of projection  529   p ′ of bottom power neckband joint component  528  of power neckband joint  520  for properly aligning and/or holding button carrier  540  in position with respect to power neckband joint  520 . Therefore, power neckband joint  520  may include various locating, datum, and/or assembly features to help properly align, support, and/or couple different components of power supply subassembly  500  to power neckband joint  520 . Then, as shown in  FIGS. 13C-13D ′, button  549  may be positioned to extend out from opening  582  along a side surface of main power housing  580  and then neckband end opening  589  of main power housing  580  may be coupled to power neckband housing portion  510  about power neckband joint  520  to form the complete enclosure of power supply subassembly  500 , such that at least a portion of button  549  and opening  582  may align with at least a portion of top portion  541  of button carrier  540 . 
     As shown in  FIGS. 14A-14M , button carrier  540  may not only include top portion  541 , front wing  542 , and back wing  548 , where portion  541  and wings  542  and  548  may together be referred to herein as button carrier frame  547 , but button carrier  540  may also include a plunger  543  and a gasket  544 . Button carrier frame  547  may include a carrier frame opening  547   o  provided through top portion  541 , while gasket  544  may be operative to rest on a top surface of top portion  541  for covering frame opening  547   o , and while a gasket opening  545  may be provided through a portion of gasket  544 . Plunger  543  may be positioned within frame opening  5470  underneath gasket  544  and may be operative to extend across gasket opening  545 . Button carrier may be formed using any suitable material(s) and any suitable process(es). In some embodiments, at least a portion or the entirety of button carrier frame  547  may be molded during a first single shot molding process that may also include molding plunger  543 , where such a first shot molding process may use a first material or first material combination, such as a clear or at least partially translucent plastic. Such a first single shot molding process may form both button carrier frame  547  and plunger  543  even though plunger  543  may be a distinct independent structure from button carrier frame  547  (e.g., plunger  543  may float between wings  542  and  548  under carrier frame opening  547   o  but may be held by a tool and suspended in place during the formation of button carrier  540 . After molding button carrier frame  547  and plunger  543 , gasket  544  may be molded onto and/or about button carrier frame  547  and onto and/or about plunger  543  during a second single shot molding process, such as using a second material or second material combination, such as any suitable TPE(s). 
     The structure of button carrier  540  may be operative to position plunger  543  along and/or against a top surface of a portion of bracket arm  562  including the free end of bracket arm  562 , such that downward depression of gasket  544 , such as by a user pressing on button  549  that may be position along a top surface of gasket  544 , may push plunger  543  downward against bracket arm  562 , which may actuate switch element  535  of switch component  534  positioned below bracket arm  562 . Gasket  544  may be operative to provide spring/damper characteristics to deliver a tactile feel to a user interacting with button  549 , while bracket arm  562  may be operative to bias plunger  543  and gasket  544  upwards away from switch component  534 , where such bias may be overcome by a user&#39;s downward force on button  549 . Gasket  544  may also be operative to provide a waterproof seal about opening  582  in main power housing  580  through which button  549  may be exposed and pushed downwardly by a user. Button  549  may include a translucent element  546  provided through an otherwise opaque button (e.g., button  549  may be formed by any suitable TPE(s) that may be similar to gasket  544 , while translucent element  546  may be made by a clear plastic that may be similar to plunger  543 ). Together, plunger  543  and translucent element  546  may be operative to convey light from a light source of power supply subassembly  500  within main power housing  580  to a user of assembly  100  (e.g., when assembly  100  is powered on). For example, an LED on PCB  530  may be operative to shine light into a first portion of plunger  543 , and plunger  543  may be operative as a light pipe to transport that light to a second portion of plunger  543  adjacent to translucent element  546  of button  549  that may then convey the light to the user. 
     As shown in  FIGS. 15-16H , for example, input subassembly  700  may include any suitable components for receiving user input commands for controlling assembly  100 , such as a center button  710 , a top housing  720 , a cover  730 , a spacer component  750 , a PCB  760 , a cable mount subassembly  770 , a first microphone mesh  780 , a second microphone mesh  786 , and a bottom housing  790 . Center button  710  may be positioned between top housing  720  and a top surface of cover  730 , where a portion of center button  710  may be operative to extend through or at least be exposed by a center opening  725  through top housing  720  in order to receive a center button depression force on a top surface of center button  710  from a user of assembly  100 . Spacer component  750  may be positioned between a bottom surface of cover  730  and a top surface of PCB  760 , where spacer component  750  may include at least one pad, such as three pads  752   a ,  752   b , and  752   c , each of which may be suspended above a respective switch provided on a top surface of PCB  760 , such as switches  762   a ,  762   b , and  762   c , such that spacer component  750  may be operative to provide a tactile feel to a user when the user provides a downward force on a particular portion of button  710  and/or front housing  720  that may exert a downward force on and/or through a particular portion of cover  730  that may exert a downward force on a particular pad of spacer component  750  that may actuate a particular switch on PCB  760 . For example, when a user exerts a downward force on a first portion  722   a  of front housing  720 , which may be identified by a depression downward into the top face of front housing  720 , or when a user squeezes first portion  722   a  of front housing  720  and bottom housing  790  (e.g., a first portion  795   a  of bottom housing  790 ) together, then switch  762   a  may be actuated (e.g., via pad  752   a ).
