Body Type Transistor Hearing Aids

Zenith Model 50-R Transistor (Body) Hearing Aid

The Zenith Model 50-R Transistor Hearing Aid was manufactured by the Hearing Aid Division of the Zenith Radio Corp. in 1957. It was an 4-transistor aid.

The Zenith Model 50-R measured 2⅝" x 1¾" x ⅝" thick, and weighed 2 oz. with battery. The aluminum case was unusual in that it was colored black rather than the light silver or gold colored cases usually used by Zenith (and other manufacturers) at this time.

The vertical rectangular microphone grill was in the front center of the case. Notice that the pocket clip ran across the microphone grill near its bottom.
