Until the 1950s, people used headphones almost exclusively for radio communication.
In 1958, John C. Koss introduced the Koss SP3 Steroephones along with a portable phonograph to patients in Milwaukee hospitals that proved revolutionary because their sound quality made them optimal for listening to music.
