A push-to-talk headset can include one or more user-actuatable switches, user-actuatable adjustment devices or the like that are electrically coupled to a pulse generator circuit. Responsive to detected state transitions of the one or more user-actuatable switches, user-actuatable adjustment devices or the like, a number of signals comprising a number of pulses may be communicated to a portable electronic device communicably coupled to the push-to-talk headset. At least a first of these signals having a first number of pulses may be used to place the portable electronic device in a push-to-talk mode. At least a second of these signals having a second number of pulses may be used by the operating system to remove the portable electronic device from the push-to-talk mode.
