Radioear Model 930 Eyeglass Hearing Aid
The Radioear Model 930 eyeglass hearing aid was manufactured by Radioear
Corporation of Pennsylvania, in 1965.
It was a 4-transistor hearing aid and had a built-in t-coil.
All the electronics were built into the right temple-piece. The other
side was made to look the same shape, but contained no electronics.

A close-up of the back of the Radioear Model 930 showing 2 "bumps". The
leftmost "bump" is for pushing the battery compartment door ajar. This
acted as the on-off switch, and also a means so you could open the door
the rest of the way to replace batteries. Immediately to the right of
this "bump" is the volume control wheel.
