ABSTRACT:
The described headsets have earpieces at the ends of acoustic tubing, the tubes being shaped about the wearer's head by a resilient frame that biases the earpieces against the wearer's outer ears. Pairs of spaced-apart strips form resilient arms of the frame and provide inner and outer guides for the acoustic tubes. The inner and outer strips are cross-connected to accommodate flexing of the frame without developing either localized stresses in the strips or significant spreading of the strips when separation of the arms is increased for putting on the headset and while it is worn.
