Electric power is provided to a two-way communications headset by creating a differential DC voltage potential between a ground conductor associated with a microphone of that headset and a ground conductor associated with an acoustic driver of that headset, thereby enabling that headset to refrain from drawing electric power from a more limited local power source.
