1. A communications headset comprising:
- a head assembly comprising;
an earpiece comprising a casing and an acoustic driver disposed therein; and
a first microphone positioned relative to the casing of the earpiece towards the vicinity of a mouth of a user of the communications headset;
an audio circuit electrically coupled to at least the acoustic driver to perform at least two different functions of the communications headset;
a control circuit; and
a first cable comprising a first conductor and a second conductor electrically coupling the control circuit to the audio circuit to enable the control circuit to provide electric power to the audio circuit to perform the at least two different functions, wherein;
at least one portion of one of the audio circuit is disposed within a portion of the head assembly;
which of the two different functions is performed by the audio circuit is determined by a voltage level of the electric power provided by the control circuit to the audio circuit via the first and second conductors; and
the voltage level is selected by the control circuit from a plurality of predetermined voltage levels based on instructions received by the control circuit indicating which of the two different functions is to be performed.

Abstract
Through a cable coupling two portions of a communications headset, conductors of the cable providing electric power from one of the portions to another are caused to do so with one of a selection of different predetermined voltage levels used to control aspects of one or more functions performed by the communications headset, including enabling or disabling functions, perhaps at least partially by controlling the manner in which the provided electric power is used.
