1. An audio device, comprising:
- a first headphone comprising a first conductive surface and a first speaker;
a second headphone comprising a second conductive surface and a second speaker;
a first comparator circuit connected to the first conductive surface, wherein the first comparator circuit is configured to generate a first detection signal when a magnitude of an impedance between the first conductive surface and the second conductive surface is less than a first detection threshold value; and
a controller configured to alter a delivery of an audio output generated from one or more of the first speaker and the second speaker when the first detection signal is received by the controller.
