KOSS is one of the biggest names in audio technology. John Koss, the founder of the company, invented the world’s first SP/3 stereo-phone in 1958. He drew inspiration from communication technology that was used during the Second World War. John Koss was inducted into the Consumer Electronics Hall of Fame for his one of a kind invention that forever changed the way people listened to music. In 1969, the Presidential aircraft Air Force One was equipped with about 50 KOSS Pro/4 stereo-phone units. The American brand is known for blending state-of-the-art technology with stunning designs. The fact that KOSS products are priced very reasonably makes them almost irresistible to audiophiles and fashionistas.
