Can you remember the last time you had a proper workout without any disturbances from your headphones falling out or giving up the ghost? The new Sennheiser/adidas CX 680i sports-oriented earphones will change that perception on the first listen. Unique and comfortable soft "earfin" design provides secure in-ear fit that stays in place as you move. Kevlar cabling resists cord fraying and tearing even under stress. These sweat-proof, 'earbud'-type headphones deliver outstanding high-energy stereo sound without the need for readjustment or the trash can. The proprietary Sennheiser 'EarFin' stability system provides a comfortable, secure fit that won't fall out during your workout. Further, the CX 680i eartips fit any size or shape ear ensuring long-term comfort without sacrificing secure support. A convenient volume adjuster keeps you in control of your tunes while a detachable extension cable lets you position your MP3 player precisely wherever YOU need it. The DuPont Kevlar reinforced cabling guarantees cord durability and flexibility where other sport headphones can't compete - like in our freakin' cold Montana temperatures. The CX 680i adidas sweat-proof, water-resistant construction lets you go your hardest during any season.
