A communications headset includes a headset enclosure and a receiver enclosure coupled thereto by various means allowing displacement of the receiver enclosure with respect to the headset enclosure at any of a variety of angles, rotations, and distances. The adaptable positioning of the receiver enclosure allows the headset to be used by a wide variety of users having different ear shapes and sizes, while providing a stable, comfortable fit and ensuring good acoustic performance. In one embodiment the receiver enclosure is slidably coupled to a ball tube having a ball that rests in a socket of the headset enclosure. The receiver enclosure can telescope along the length of the ball tube and can rotate about an axis of the tube. The ball can be rotated in the socket to position the receiver enclosure at any of a variety of angles relative to the headset enclosure. A voice transmitter is also coupled to the headset enclosure so as to allow adjustment of length, angular position, and rotation.

A headset provides for user selectable switching between various frequency responses for the headset through manipulation of mechanical acoustic elements of the headset. The acoustic elements allow adjustment of the transmission paths between a transducer element in the headset and the user's ear canal, and adjustment of the resonant characteristics of the headset housing itself. Adjustment of the transmission path is made by manipulation of ports and openings in and between various volumes containing the transducer and the ear canal, and through the use of various resistant elements along such transmission paths. The user is able to independently and mechanically alter the inductance and resistance along the transmission path, and thereby independently control the high and low frequency response of the headset. Adjustment of the headset resonance is also made by manipulation of ports between interior volumes and external ports, and through variation in the size of the interior volume of the headset, thereby and increasing or decreasing the compliance of transducer. The acoustic switching may be embodied with either discrete or continuous adjustment of the acoustic elements of the headset.
