Abstract

An apparatus and method for automatically remotely controlling an audio source providing the apparatus with audio for being audibly output to a user of the apparatus entails monitoring various sensors to determine whether or not one or more ear couplings of the apparatus are positioned in close proximity to one or both of the user's ears to determine whether the user is listening to the audibly output audio with either one or both ears, or is not listening at all. In response to changes in whether the user is listening with either one or both ears, or whether the user is listening at all, the audio source is automatically signaled with one or more commands to cease or resume providing the audio to the apparatus, perform or cease performing various alterations on the audio before providing it to the apparatus, etc.
