Abstract

A lightweight, monaural communications headset is disclosed which is readily adjustable to be worn on either the right or left ear of a wearer. The disclosed headset consists of two housings, one for holding electronic circuitry for the headset, and the other for holding an acoustical transmitter. The two housings are coupled with a swivel or ball-and-socket coupling, so that the device may be positioned behind either the right or left ear of a wearer. The transmitter housing is provided with acoustical port holes on both of its sides to further facilitate the reversible wearing of the device. The disclosed headset is constructed from lightweight materials so that it is self-supporting, and causes minimal discomfort to the wearer.
