ABSTRACT:
Acoustic headsets, especially for transmitting sound from stereo transducers to the listener's ears, include two tubes, earpieces at first ends of the tubes, and a frame for constraining the tubes into a convenient U-shape near the wearer's face. The headset has resilient arms at the sides of the U-shaped frame, and more particularly, the arms have resilient inner and outer strips along respective ones of said tubes, facing toward and away from the center line of the frame. The strips are interconnected at their extremities, and in the exemplary embodiment the inner and outer strips of each arm are interconnected by a bridge between the extremities of the strips.
