ABSTRACT:
A telephone headset utilizing a foldable microphone boom that is operable in both noise canceling and omnidirectional modes is disclosed. The headset generally comprises a main body, a boom extending between a pivoting end and a microphone housing for housing a two-port microphone, and a pivoting hinge coupling the pivoting end of the boom to the main body and enabling the boom to rotate about the pivoting hinge relative to the main body. The boom is adapted to be positioned in a first extended position in which the microphone is located away from the main body and both ports are open and a second folded position in which the microphone housing is at least partially in contact with the main body to generally close one of the ports.
