You won't have to worry about your headphones falling out during a tough workout with the PMX 680s. Designed by Sennheiser and adidas, they feature a rugged headband with an ergonomic behind-the-neck design that keeps the earbuds securely in place for running, lifting, and more. Kevlar® reinforced cabling plus a sweat- and water-resistant design ensure long-term durability. High-quality Sennheiser drivers and construction guarantee outstanding, high-energy sound.
The PMX 680s come with a built-in volume control that makes it easy adjust the sound without having to fumble with your player. If you wear your music player in an armband while exercising, the headphone's attached short cable is the perfect length to avoid getting tangled. If you need more cord length to put your player on a belt clip or in a pocket, just plug in the included extension cable and you're all set. A handy clothing clip helps keep the cord out of your way.
