Body Type Transistor Hearing Aids

Conny Model CH-101 Transistor (Body) Hearing Aid

This Conny Model CH-101 transistor body hearing aid was made by Conny Industrial Co., Ltd. of Tokyo, Japan in 1961 and distributed in the USA by Dunaj Import-Export of Chicago, IL.

The Model CH-101 measured 2" x " x 7/16" (6.7 x 2.2 x 1.1 cm) and weighed 1.1 oz (32 g) without the battery. The case was light gold-colored anodized aluminum.

Note the elegant diamond-shaped microphone grill comprised of four smaller diamond shapes with a blue grill cloth behind.

Bottom view of the Conny Model CH-101 transistor body hearing aid with the green battery compartment pulled out.

This hearing aid took an unusual-sized battery that was exactly 15 mm in diameter. (I cannot find any record of such a battery.)

The battery holder of the Conny Model CH-101 transistor body hearing aid had to be pulled all the way out so you could replace the battery. It took a good tug to pull it all the way out.
