  • Patent number: 5381486
    Abstract: A communication headset is disclosed having a microphone for transmitting the user's voice and a receiver for transmitting audio signals into the user's ear. In a monaural configuration, the headset includes a resilient, generally U-shaped headband, to be worn over the head, having a housing adjustably attached at one end and a stabilizing clip at the other. The receiver assembly is mounted to the housing with a ball and socket type arrangement, allowing the receiver assembly to rotate axially and pivot in a spherical fashion with respect to the housing, thereby increasing comfort and acoustic coupling with any size or shape ear. A binaural configuration is also disclosed wherein the stabilizing clip is replaced with a second receiver assembly, ball and socket joint, and housing.The microphone is mounted on the distal end of a microphone boom for positioning adjacent the user's mouth.
