ABSTRACT:
A telephone headset including a boom microphone, a earphone, and an ear support constructed and arranged to be adjustable and comfortable for a wearer. The headset is configured with an adjustable ear support to fit a variety of ear sizes without affecting the balance of the ear support on the ear of the wearer. The ear support includes a rotational hinge which is biased into a given position by a compression washer. The earphone is removably and adjustably attached to a mounting ring which in turn is movably attached to the ear support by a spring biased ball and socket joint. The combination of flexible joints and removability of the earphone provides the degrees of freedom and stiction necessary to permit the earphone to be worn comfortably on either ear of the wearer. A strain relief for the electrical connections is attached to the earphone which directs the electrical connections toward the plane of the head, thereby eliminating a torque which otherwise would tend to dislodge the ear support from the ear. The earphone includes a series of openings in its rear surface to maximize its acoustics. The boom microphone includes a spring biased ball and socket joint to movably fix the orientation of the microphone with respect to the wearer to a good comfort level. The boom microphone ball and socket joint is configured with a tab and stop to prohibit 360 degree rotation of the boom to prevent strain on the electrical connections to the microphone.
