about Koss

How long has Koss Corporation been around?
Koss Corporation was founded by John C. Koss in 1953 as a television rental company. In 1958, John Koss, along with his partner Martin Lange JR., developed the world's first stereophones, the SP/3. Today, Koss offers a complete selection of over 40 different models of stereophones, ranging from our top-of-the-line electrostatic stereophones, noise reduction systems, and infrared and radio frequency stereophones to our line of lightweight, portables.
