Turn up the heat and let nothing get in your way! The Sennheiser/Adidas PMX 680 neckband headphones are not only lightweight and sturdy, they also stay extremely secure in your ear while you run or work out in the gym. Sound-wise, their high-output drivers deliver a powerful and energizing stereo sound.
These headphones have been designed and tested for heavy movement. Their strain relief parts are made of highly-flexible, shock-absorbing material while the cable is Dupont Kevlar reinforced, offering you unmatched strength and durability. Even under the toughest of conditions, the PMX 680 Sports have been found to function well and maintain their flexibility.
The PMX 680 Sports also feature a unique moisture protection system - it protects the sound system from sweat and water, no matter how heavy you work out (and sweat) or how heavy the rain may be.
