Abstract
A headphone earbud may include a sensor to determine characteristics of an environment around the headphone earbud. The sensor may be integrated with the headphone earbud to measure a distance from the headphone earbud to a user's ear drum. This distance may be used to control an audio output of the headphone earbud, such as through an adaptive noise cancellation (ANC) algorithm. Control over the audio output may be performed by an audio integrated circuit (IC) integrated within the headphone earbud or within a mobile device coupled to the headphone earbud.
