Designed exclusively for use with Apple's iPhone, iPod and iPad products! Can you remember the last time you had a proper workout without any disturbances from the blaring gym radio, falling earbuds or clatter of machines? The new Sennheiser/adidas CX 680i sports earphones will change that on the first listen. These sweat-proof, noise-isolating ear-canal 'phones deliver outstanding, high-energy stereo sound while blocking out up to 20 dB of gym noise. The exclusive EarFin provides a comfortable, secure fit that won't fall out during your workout. Further, the CX 680i can be adapted to fit ANY ear using the supplied fit kit. This will ensure long-term comfort and exceptional isolation to enhance sound quality and concentration. A convenient volume adjuster and 3 button control with mic let you manage calls and playlists at the touch of a button. The DuPont Kevlar reinforced cabling guarantees durability and flexibility where other sport headphones can't - even in cold temperatures. The sweat-proof, water-resistant construction lets you go your hardest during any off-season.
