Sennheiser PMX680 1/8in. (3.5mm) Connector Earbud Adidas-Inspired Sport Earphone


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. 20°F, 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.
