In 1953, John C. Koss founded a company offering TV sets rental for hospitals, five years later, together with Martin Lange, he created the SP/3 – world’s first stereo headphones and at the same time he established the Koss Corporation. Already in the 60s, the company was very successful in terms of marketing. In 1966, Koss reacted quickly to the market needs by launching the Koss Beatlephone headphones carrying images of the Beatles members. The company also boasted its Pro-4 model that was mounted on board the Air Force One. In the 70s, when Koss moved to a new factory, where testing the equipment became one of the key areas, more promotional campaigns were launched. The company increased its production simultaneously increasing the emphasis on its quality. In addition, in 1989, it introduced the Lifetime Limited Warranty Policy, further building confidence in the brand. A year later, Koss introduced the ESP / 950 electrostatic headphones, and in 1993 the QZ / 1000, a special noise-reducing model.
In the 90s, the company was taken over by the sons of John C. Koss, who kept introducing new innovations, extended the product range and took care of the highest quality.
Custom Pro are headphones manufactured by Koss under the Realistic brand for the American audio store network called Radio Shack. According to the original specification from the 80s, this model is “a professional stereo headset designed to provide years of flawless stereophonic listening – without distortion and with full sonic range. The exclusive bass port strengthens the lows delivering a rich bass response. ”
Old pads have been replaced with properly selected substitutes made of eco leather, which were moisturized and protected with a balm based on lanolin, aloe, beeswax and Carnauba wax. The headband and ear muffs were cleaned and also were moisturized and protected with a balm based on lanolin, aloe, beeswax and Carnauba wax.
Included in the set are specially designed and hand-made solid headphone stands.
