ABSTRACT:
The present invention provides an over-the-ear headset and donning method which advantageously allow for improved comfort, sound quality, and stability on the ear. In accordance with the present invention, the headset includes an earhook, and a bias structure connected to the earhook. An extension member is connected to the bias structure, and a receiver capsule is movably connected to an end of the extension member. The headset advantageously provides bias forces both behind the user's ear and substantially normal to the orientation of the user's outer ear, allowing for improved acoustic coupling to the ear and enhanced sound quality.
