Built to stand the test of time
Koss has been pleasing ears since 1970 with their PRO4AA headphones. The vintage looks of the latest PRO4AA nicely compliment their sweet sound. Designed for use in recording studios, these unique closed-back headphones provide excellent noise isolation, so external distractions don't disrupt your listening. They present your music with clarity and accuracy, so you can experience it as the artist intended.
The PRO4AA combines durability and comfort, with a rugged exterior wrapped around the softly padded headband and earcups. The 8-foot coiled cable gives you room to move about as you listen, perfect for use with your home system. There's even a boom microphone mount on the earcup, for use in broadcast production.
