Abstract A headset is provided wherein each ear piece is supported to the headband by means of a support member having a wedge shaped opening therein. A wedge is positioned within the support member opening and the headband is secured to the wedge. The wedge resiliently urges a fork attached to the ear piece against the support member thereby providing a slideable, frictional engagement.
