In 1957 the only way you could listen to music was monophonically. It wasn’t until 1958 when John C. Koss transformed his Hospital Television Rental business into a worldwide headphone icon when he invented the world’s first SP/3 Stereo Headphone and forever changed the way we all listen to music.

Create with Koss. What projects are you working on this week?
