  • Patent number: 4420657
    Abstract: A lightweight adjustable headset is disclosed for use with telephones. The headset includes a housing having a microphone boom mounted in a manner to permit rotational and translational movement. A support member is provided for affixing the headset to the wearer. In one embodiment of the subject invention, which includes a wire headband for support, a cushion is affixed to the housing and is adapted to rest against the ear of the wearer.
