Abstract: A headset presents audio sounds with first and second speakers disposed in first and second earcups that fit over first and second of an end user's ears. One ear cup adjusts with a greater travel distance relative to the other earcup so that the headset rests on the end user head with the one earcup raised above an ear and the other on an ear.

In addition, when only one ear is covered by an earcup, the audio presentation converts from stereo to monoaural.
