Koss P9 Ear Clip Headphones feature an around-the-head design that won't interfere with a hat or other head gear. Additionally, the single-entry 4.0' long cord provides better cord management, especially for travel & storage. The headphones feature a 40-20,000 Hz frequency response and a side-firing design which projects sound into the ear canal sideways for a more natural sound. Need to adjust the volume? There's no need to reach into your pocket and take out your music player, the P9s feature an in-line volume control so you can easily adjust your music to the perfect listening volume.
