Push-to-talk audio devices and methods are provided. The audio device can include a tip-ring-ring-sleeve connector having a sleeve, tip, first ring, and second ring that are electrically isolated from each other. A microphone and a push-to-talk switch selectively operable to provide an electrical short across the microphone in a first state and to remove the electrical short from across the microphone in a second state are electrically coupled between the sleeve and the second ring.
