Behind-the-Ear (BTE) Transistor Hearing Aids

Tonemaster Model ME-2 "Midget Earette"  Behind-the-Ear Hearing Aid

This Tonemaster model ME-2 "Midget Earette" behind-the-ear hearing aid  was manufactured by the Tonemaster Manufacturing Co. of Peoria, IL in 1957.

This 3-transistor Tonemaster aid measured 1 11/16" x ¾" x 11/16" (4.3 x 2.0 x 1.7 cm). It was unusually thick for a BTE aid. It weighed 0.6 oz. (16 g).

Like other BTE aids of its vintage, it had an external receiver like those used on body aids.

Because the volume control and microphone port were on the back of the aid, it could be worn in either ear.
