Koss Pro4AA headphones set the standard for full-size professional headphones. They were released in 1970 as the first dynamic headphones with full frequency response, high fidelity and excellent noise isolation. The model ceased production in the late 80s, but Koss quickly resumed production of the Pro4AA due to overwhelming demand. Since then, they have remained a leader among studio headphones in the TV, radio and recording industries. Koss Pro4AA meets the stringent demands of TV and recording professionals who want reliable equipment and quality results.
