Wireless listening device

A portable listening device comprising:

• a device housing defining an internal cavity;
• an acoustic port formed through the device housing;
• an audio driver disposed within the device housing and aligned to emit sound through the acoustic port;
• a multifunction input button coupled to the device housing, the multifunction input button having a distal end and a proximate end, a centerline between the distal and proximate ends and an axis of rotation located between the center line and the proximate end, and wherein the multifunction input button further comprises a faceplate coupled to a button housing element such that the faceplate defines an exterior surface of the portable wireless listening device and the button housing element is part of the device housing;
• an electronic circuit disposed within the device housing that requires power to operate and is configured to detect activation of the button;
• and
• a battery disposed within the device housing and operable to provide power to the electronic circuit;
• and
• wherein the multifunction input button further comprises a gasket disposed between the faceplate and button housing element at a location between the centerline and the proximate end, wherein the gasket provides internal spacing between the faceplate and the button housing element and is operatively coupled to bias the faceplate away from the button housing element.

A portable wireless listening system comprising:

• (i) a pair of earphones including a first earphone and a second earphone, each of the first and second earphones comprising:
• a device housing defining an internal cavity;
• an acoustic port formed through the device housing;
• an audio driver disposed within the device housing and aligned to emit sound through the acoustic port;
• a multifunction input button coupled to the device housing, the multifunction input button having a distal end and a proximate end, a centerline between the distal and proximate ends and an axis of rotation located between the center line and the proximate end, and further comprises a faceplate coupled to a button housing element, wherein the faceplate defines an exterior surface of the portable wireless listening device and the button housing element is part of the device housing and is coupled to the bottom housing element by a retention clip at the distal end of the multifunction input button and by a wireform axle at the proximal end of the multifunction button;
• an electronic circuit disposed within the device housing that requires power to operate and is configured to detect activation of the button;
• and
• a battery disposed within the device housing and operable to provide power to the electronic circuit;
• and
• (ii) a case for storing and charging the pair of earphones, the case comprising:
• a case body having a first pocket sized and shaped to receive the first earphone and a second pocket sized and shaped to receive the second earphone;
• a lid attached to the case body and operable between a closed position where the lid is aligned over the first and second pockets and an open position that enables the first and second earphones to be placed in or removed from their respective pocket;
• a battery;
• and
• a charging system operatively coupled to the battery and configured to charge the first and second earphones when the earphones are positioned within their respective pockets.
