SP/3

In 1958, John C. Koss invented personal listening with the world’s first SP/3 stereophone. Koss sought to replicate the excitement of a live musical performance. The original SP/3 stereophone allowed listeners to experience sound as they had never before, bringing them closer to the music they love.
