Enjoy high fidelity sound quality while remaining connected to the outside world with the Koss KSC21 sport clip headphones. These over-the-ear headphones deliver a wide-range, extended frequency response through soft foam ear cushions that guarantee an open, hear-through sound. The pivoting ear plates provide a better fit than most clips, so you can place them exactly for the perfect fit.
KSC21’s are super light making them feel practically weightless, even after hours of high fidelity listening and the straight, dual entry 4 foot cord with 3.5mm plug allows you extensive freedom of movement to ensure that you can position the headphones for optimum listening. When not in use, simply tuck them into your briefcase, gym bag or pocket and carry them with you wherever you go.
This is all backed up by the Koss Stereophones Limited Lifetime Warranty.
When you choose the KSC21, you’re rewarded with only the best sound.
