Radioear Model 82 (Zephyr) Vacuum Tube Hearing Aid
The Radioear Model 82 (Zephyr) Vacuum Tube Hearing Aid was
manufactured by E. A. Myers & Sons of Pittsburg, PA in 1952.
An interesting feature of this hearing aid was the optional plug-in extension
microphone (top right). The earpiece is to the left.
It measured 2¾" x 2" x ¾".

An unusual feature of the Radioear Model 82 was it had an optional
external microphone that you could plug in (shown here). The external
microphone had a short 9" cord so you could put the hearing aid in an
inside pocket and pin the external microphone to your coat for example.
(The back of the mic has a broach-like pin for fastening it to your
clothes.)
