Body Type Transistor Hearing Aids

Zenith "Envoy" Transistor (Body) Hearing Aid

The Zenith "Envoy" transistor hearing aid was manufactured by the Hearing Aid Division of the Zenith Radio Corp. in 1960. It was a 4-transistor aid.

A little unusual in shape, its gold metal case measured 2¼" x ¾" x ⅜" thick.

The volume control is on the left side. A three position switch on the right side is labeled "Off", "On" and "HI" (high frequency emphasis).
