Body Type Transistor Hearing Aids

Zenith "Extended Range" Transistor (Body) Hearing Aid

The Zenith "Extended Range" transistor hearing aid was manufactured by the Hearing Aid Division of the Zenith Radio Corp. beginning in January, 1960. It was an 5-transistor aid.

The Zenith "Extended Range" measured 2½" x 1¾" x ⅝" thick, and weighed 2 oz. with battery. The case was gold-colored anodized aluminum with a silver-colored lower front panel.

The microphone grill was an upside down "keystone" shape on the upper front of the hearing aid. Below it on the silver-colored panel is the name "ZENITH" and the Zenith crest (bottom right).
