Abstract
An audio system comprises: a first earpiece comprising at least one acoustic driver, and circuitry that comprises at least one microphone; a housing configured to receive the first earpiece and enclose around the first earpiece; an acoustic cavity within the housing configured to provide a predetermined volume that is acoustically coupled to the acoustic driver when the first earpiece is housed within the housing. The first earpiece or the housing comprises circuitry configured to: (1) measure a response from the microphone to an acoustic wave, and (2) calibrate the circuitry based at least in part on the measured response.
