The Pro4AA headphones from Koss provide high-quality audio in a vintage design. First introduced in 1970, the Pro4AA over ear headphones were the first dynamic headphones to deliver true full frequency and high fidelity performance with impressive noise isolating capabilities.
Koss Pro4AAs meet the stringent demands of broadcast and recording professionals who require reliable equipment and superior performance. The full size professional headphones keep unwanted sounds out while letting every note in.
Whether you’re a sound professional or an audiophile, Pro4AAs deliver superior isolation, accurate reproduction and sound intensity, and the excitement of a live performance with every recording. Connecting with your music has never sounded so good.
These stereophones have an 8 foot coiled cord with 6.3 mm (1/4") plug.
They are newly manufactured and come fully packaged fresh from Koss.
