ABSTRACT:
An adjustable telephone headset for the hearing impaired comprising a left and a right ear piece, a speaker within each ear piece, an input device, such as a microphone or magnetic induction pickup within one of the ear pieces, and an amplifier connected between the input device and the speaker. Optionally, a switch may select between either a microphone or a magnetic induction pickup as the choice of input device. A wearer of the headset may place a telephone receiver against the microphone or magnetic induction pickup, allowing an amplified telephone conversation to be heard by both ears. Independent volume controls for each speaker allow individual adjustment to compensate for variations in hearing loss, and optional tone controls for each speaker similarly allow optimum compensation for differences in tonal response in the wearer's ears. An optional remote microphone allows use as a conventional hearing aid when not engaged in telephone conversation.
