This headset includes a single earphone and a boom mounted microphone. The headset is mounted on a yoke adapted to fit over a wearer's head with the transducers on either side of the wearer's head. The earphone transducer is in a housing spaced from the wearer's ear and coupled thereto through a flexible tube and an earpiece. A reversible microphone is mounted at the end of a curved conduit whose opposite end is supported on the housing by an electrical connector including an articulated plug assembly which permits rotation and tilting of the conduit with respect to the housing while maintaining electrical connections between the microphone and circuit elements within the housing. The conduit is curved to bring one side or the other of the microphone adjacent to the wearer's mouth when the headset is in place, and the curved conduit is properly positioned by appropriate rotation and tilting of the articulated assembly. The rotation and tilting accommodates shifting of the headset from one side to the other of the wearer's head, while maintaining the microphone in position adjacent one corner of the wearer's mouth.
