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, e.g. -10 degree celsius, the PMX 680 Sports have been found to function well and maintain their flexibility.

There is a reflective stripe on the neckband, providing extra visibility and safety, especially if you prefer to run after sunset. These earphones come with a short cable which allows for a hassle-free experience especially when you wear your audio player around your neck or on your arm. However, you may attach the extension cable which comes integrated with a volume control, whenever you require added cable length. 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.

Avoid using headphones with the volume turned up for an extended period of time. Doing so can damage your hearing. For your own safety, please do not use when driving or cycling
