Eyeglass Style Transistor Hearing Aids: 1954-1990

Beltone "Slimette" Eyeglass Hearing Aid

The Beltone "Slimette" eyeglass hearing aid was made by Beltone Electronics Corporation of Chicago, IL in 1957.

All the electronics were housed in one temple piece. Thus, these eyeglass hearing aids could be configured for one ear, or both ears.

The hearing aid pictured here is housed in the right temple-piece. The thick left temple-piece is a dummy made to look the same as the other side.

The Beltone "Slimette" was a 3-transistor aid.

The Beltone "Slimette" was unusual in that there was a tiny circuit board in the hollow temple piece ahead of the ear. Here is the top view showing the electronic components.
