Sennheiser MX 680 headphone

3.5mm, 18 - 20000Hz, 118dB, 16Ω Run faster and further, or work out harder. The Sennheiser/adidas MX 680 Sports earphones let you achieve both. Their high-output drivers deliver a powerful and energizing stereo sound, motivating you while you run that extra mile or lift the newly-added pounds on your curlbar.

These earphones 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 MX 680 Sports have been found to function well and maintain their flexibility.

Their short cable 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 MX 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.
