Body Type Transistor Hearing Aids

Maico Model Q "Transist-Ear" Transistor (Body/Barrette) Hearing Aid

The Maico Model Q was manufactured by Maico Electronics, Inc. of Minneapolis, MN in 1954.  The name "Maico" was derived from the initials of the Medical Acoustic Instrument Company.

The Model Q was a 2-transistor barrette-style hearing aid. The front of the case was anodized metal, and the back was black plastic. It measured 2⅜" x 1⅜" x ⅝" thick.

The volume control is in the top left corner, while the microphone opening is in the design lines (bottom center).

The cord, receiver (earpiece) and ear mold are shown to the right. The cord was only 5¾" long as this hearing aid was worn in the hair close to the ear.
