|Sound powered telephones are ideal, in that
they function without an external power source. Earpieces and mouthpieces are identical, so a headphone
could still be used if an earpiece or mouthpiece should go bad.
Handsets had a pushbutton switch that had be pressed to transmit or receive., headsets were push to talk. Sound Powered phones require protection from impact, and strain on the wiring.
