Koss Headphones - Born in Milwaukee

In 1958 John C. Koss invented the World's first SP/3 Stereophone in Milwaukee, Wisconsin and forever changed the way we all listen to music.

For over 60 years iconic headphones like the Pro4/AA, HV/1A, ESP6, Porta Pro®, KPH30i and Pro4S were all born in Milwaukee, WI too.
