Acoustic Technology Products That Time Forgot:

The Konexx Koupler 204 Acoustic Coupler (1994)

This nearly end-of-life, 9-volt battery-operated acoustic coupler allowed small businesses to send faxes and check e-mail acoustically using a telephone receiver – at a blazing-fast 26kbps (maximum) – for only US$149 (not adjusted for inflation).
