For Music Lovers Who Keep It Moving

Working out, staying in, or getting out of town—the lightweight, sport-friendly KSC75X headphones will keep the music going every step of the way. A revision of the company’s KSC75 model, this collaboration has the same clip-on, on-ear style, now with a custom midnight blue colorway and a one-touch remote for controlling tracks and taking calls. The pivoting clips fit comfortably over the ear, while the soft foam cushions provide an open sound for those who like to stay connected with their surroundings. The dynamic drivers ensure detailed sound reproduction with a punchy bass response, and because the KSC75X is smartphone compliant, you can enjoy greater volume with low-voltage portable devices. Bring these headphones everywhere with confidence: They’re backed by Koss’s legendary lifetime warranty.

About Koss

If we were to write a history of audio companies in the US, Koss would land on the first page. Not only did the Milwaukee, Wisconsin–based company make the world’s first stereo headphone, the SP/3, in 1958, it’s also responsible for the first self-energizing electrostatic headphone, the first dynamic headphone to deliver all 10 audible octaves, and a standard-setting infrared wireless headphone. Over the years, Koss headphones have made it onto Air Force One, into the Smithsonian, and onto the heads of such music icons as Neil Diamond, Tony Bennett, and Pete Fountain. Founder John C. Koss was inducted into the Audio Hall of Fame in 1979 and the Consumer Electronics Hall of Fame in 2000.
