Sennheiser Adidas CX680 Sports Earphone

Go ahead. Play as hard as you want. The Sennheiser/adidas CX 680 Sports ear canal phones will never slow you down. They will however, ensure a high attenuation of ambient noise and get you focused on both your music and work out. An optimal and secure fit in the ear-canals is assured with Sennheiser's EarFin holding system as well as the different sizes of ear adapters (included in delivery).

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 Sennheiser-adidas CX 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 CX 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.
