The founder of Milwaukee-based Koss Corporation and the man credited with inventing stereo headphones has died.
John C. Koss died Tuesday, Dec. 21 at the age of 91, according to a post on the company’s website.
Koss, a former chairman of the company that bears his name, started the business in Milwaukee in 1953 as a television rental service for hospital patients.
According to the post it was five years later that Koss and partner, Martin Lange, Jr. developed the SP/3 Stereophone, which was key in launching the stereo headset industry worldwide.
“Dad loved music and the experience of a live performance,” said Michael J. Koss, current chairman and CEO of Koss Corporation.
“Like many legendary entrepreneurs, our founder channeled his passion to create a revolutionary product. Today, it’s clear that his innovation changed the way the world listens to music.”
Headphones that the senior Koss developed gained countless uses, including in the recording industry. One such product, the Pro/4 Series became the official headphones on the presidential jet, Air Force One, eliciting special pride.
“As a member of the reserve Air National Guard, it’s safe to say, one of Dad’s proudest moments in business was when Koss Stereophones became part of the Air Force One in-flight entertainment system,” said Koss’ son.
