In 1958, the American manufacturer for the first time offered high-quality sound lovers a radically new experience in listening to music using the revolutionary Stereophone SP/3 headphones, which allowed, in the words of company founder John C. Koss, to “recreate the excitement of a live musical performance.” ” Since then, Koss headphones have remained the recognized global standard for high-quality sound.
