Abstract

An audio system for an ear mountable playback device (HP) includes a speaker (SP), an error microphone (FB_MIC), which senses sound being output from the speaker (SP), and a sound control processor. The processor is configured for controlling and/or monitoring a playback of a detection signal or a filtered version of the detection signal via the speaker (SP), recording an error signal from the error microphone (FB_MIC), and determining whether the playback device (HP) is in a first state, where the playback device (HP) is worn by a user, or in a second state, where the playback device (HP) is not worn by a user, based on processing of the error signal.
