Vintage Binaural Equalizer by Starkey - RARE Hearing Aid Adjuster Tone Generator

Description

This vintage Binaural Equalizer is a rare hearing aid accessory developed by Starkey in the early 90s. It is designed to produce a tone to check that both of your hearing aids are adjusted to the same level. The device does make a sound when triple a batteries are put in and the button is pressed, but I am not sure if it is the correct original sound or not. More information on the device can be found in the link below. Please see pictures for details.
