Abstract
A lightweight communications headset includes a headband adapted to be worn on user's head. A speaker housing is carried by the headband and defines an acoustic chamber. A speaker mounted within projects sound waves into the acoustic chamber. The headband carries a pair of earpieces which are positionable adjacent to the user's ears for delivering sound thereto. The acoustic chamber is coupled to earpieces through acoustic passages which transmit sound waves produced in the acoustic chamber to the earpieces. The earpieces preferably include removable in-ear inserts, which may be constructed for insertion into the auditory canals of the user's ears. Since the in-ear inserts are removable, the headset can readily be configured for a variety of applications.
