ABSTRACT:
The present invention is a stereo headset system for use with a stereo headset device and a stereo sound system. The stereo headset device is of the stethoscope type and has a pair of sound tubular mains. A coupling plug is mechanically and acoustically coupled to the pair of sound tubular mains. The stereo headset system includes an enclosure having a first chamber, a second chamber, a third chamber and a fourth chamber. The first and second chambers are mechanically and acoustically coupled to the coupling plug of the stereo headset device. A first electro-acoustic transducer is disposed in the third chamber of the enclosure and is acoustically coupled to the first chamber of the enclosure. A second electro-acoustic transducer is disposed in the fourth chamber of the enclosure and is acoustically coupled to the second chamber of the enclosure. The third and fourth chambers of the enclosure are water-proofed. A control unit includes a double pole relay and a double potentiometer both of which electrically couple in series the two output channels of the stereo sound system to the first and second electro-acoustic transducers so that the stereo headset system is able to transmit sounds from the stereo sound system through the stereo headset device to an individual who is in a wet environment during both social and recreational periods.
