Now you can run faster and further or work out harder in all seasons; the Sennheiser/adidas MX 680i Sports earphones helps you achieve your fitness goals. The unique 'ear fin' structure offers soft, pliable, easy fit into the outer ear meaning you'll still be able to hear what's going on around you. The MX 680i proprietary high-output audio drivers deliver powerful, energizing stereo sound, motivating you to run that extra mile or lift the newly-added pounds on your curl bar. The convenient 680i microphone and controller is built-in and ready for your iPhone or Apple player. The adidas MX 680i earphones have been expressly designed and tested for heavy-duty activities and extreme sports use. All strain relief joints are made of a flexible shock-absorbing material while the cable construction is Dupont Kevlar reinforced, which offers unmatched strength and durability of cord at all stress points. So even under the toughest of weather conditions (e.g., our Montana -15 ~ -20 degree celsius winter mornings), the MX 680 Sports have been found to function well and maintain their full flexibility.

The Sennheiser MX680i short cable allows for a hassle-free experience especially when you wear your audio player around your neck or on your arm strap. However, you may attach the inlcued extension cable -- which comes integrated with a volume control -- whenever you require added cable length. The MX 680i 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. Variety of ear-adapters (S/M/L) included in the provided accessories kit so you can perfectly customize your fit. The strong 2 year manufacturer's warranty is standard ONLY when purchased from true Sennheiser-verified headphone dealers -- like HeadRoom!
