Abstract
An audio player includes an audio headset having two earpieces. A playback circuit provides one of a stereophonic program and a monaural program to the audio headset. The monaural program may be created by mixing channels of the stereophonic program. A mode control is coupled to the playback circuit and to the audio headset. The mode control detects when at least one of the two earpieces is not adjacent a listener's ear and causes the playback circuit to deliver the monaural program to the audio headset.
