Abstract
A cordless, wireless headset to block unwanted sound waves and/or noise from entering the ears of a user. The headset (FIG. 5) contains an electronic receiver, an audible tone/alert generator, volume control/switch and battery. The wireless headset would permit freedom of movement during sleep without danger of being entangled by cords/wires. The wireless headset would be secured to the ears and head of the user while sleeping by a Top head-strap, a Rear head-strap and Chin-strap. Referencing FIG. 1, the wireless headset will receive and interpret signals from remote sound sensor(s) and/or motion detection sensor(s). Remote sensor(s) would transmit radio signal(s) to the headset when an unwanted sound or motion is detected. The signal would be received in the wireless headset and an audible tone would be generated in the ear of the user, to alert of an important event.
