Can you remember the last time you had a proper workout without any disturbances from your headphones falling out or giving up? The new Sennheiser/adidas MX 680 sports earphones will change that on the first listen. These sweat-proof, earbud 'phones deliver outstanding, high-energy stereo sound without the need for readjustment or the trash can.

The EarFin stability system provides a comfortable, secure fit that won't fall out during your workout. Further, the MX 680 is customizable for any size or shape ear. This will ensure long-term comfort without sacrificing support. A convenient volume adjuster keeps you in control of your tunes while a detachable extension cable lets you position your MP3 player where YOU want it.

The DuPont Kevlar reinforced cabling guarantees durability and flexibility where other sport headphones can't - even in cold temperatures. A sweat-proof, water-resistant construction lets you go your hardest during any off-season.
