Koss Corporation: Innovators in High-Fidelity Sound

Founded in 1958 by John C. Koss, Koss Corporation pioneered the personal listening experience with the invention of the world’s first stereophone, the SP/3. Koss set out to capture the thrill of live music in headphones, and this dedication to audio excellence quickly made the brand synonymous with high-fidelity sound. Legendary models like the Pro/4AA, celebrated for its full-spectrum range and sound isolation, built a foundation of trust among music lovers and professionals.

Koss has since continued to redefine what’s possible in personal audio with releases like the HV/1A, capable of delivering an impressive 10-octave range, and the enduringly popular Porta Pro, known for its comfort and refined sound. Today, Koss headphones continue to inspire listeners with uncompromising sound quality, innovative design, and a timeless commitment to bringing people closer to the music they love.
