1. A wireless in-ear headphone comprising:
a device housing that defines an interior cavity;
a nozzle extending away from the device housing and defining an audio port that opens to the interior cavity;
a deformable ear tip having a central opening fitted over the nozzle;
an audio driver disposed within the device housing and aligned to emit sound through the audio port;
a wireless antenna and wireless circuitry disposed within the device housing, the wireless circuitry configured to establish a wireless communication link with a host device over the wireless antenna;
a microphone;
an active noise cancellation system configured to generate destructive interference waves to counter audio picked up by the microphone;
a button control disposed at an exterior surface of the device housing and configured to receive a user input;
a controller disposed within the device housing and operatively coupled to the wireless circuitry and to the button control, wherein the controller is configured to process audio content received from the wireless circuitry and deliver the processed audio content to the audio driver for output through the nozzle, and wherein the controller is further configured to adjust a setting of the in-ear headphone in response to the button control;
a battery disposed in the device housing and configured to provide power to circuitry within the device housing; and
a plurality of electrical contacts disposed along a surface of the device housing and electrically coupled to the battery to enable the battery to be charged from an external power source.
