ABSTRACT:
A headset is provided which includes an inverted cup-shaped housing. The housing contains a rigid membrane which separates the housing into an upper chamber and a lower chamber. An inertial transducer is positioned in the upper chamber secured to the membrane. Electrical leads extend into the transducer through water tight connections. A headband is provided to secure the headset to a listener's ear and a cushion is provided about the open bottom end of the headset housing. Only the transducer itself is water tight. Both the upper and lower chambers of the housing freely permit the passage of water.
