The CX 685 In-Ear Adidas Sport Headphones by Sennheiser are durably designed for music and sports enthusiasts. For continuous active wear they are built from flexible shock-absorbing, sweat-proof and water resistant material.
The in-ear design is engineered to stay in the ear canal during high volume intense sports or workout sessions. The headphones have an EarFin hold design and multiple sized ear-tips that customize to the shape of your ear canal for a comfortable and reliable fit. Secure fit allows noise attenuation to block-out loud distractions to stay focused.
In addition, the rugged para-aramid reinforced cable is attached for strength and reliability. At the end of the cable a 1/8" (3.5mm) mini stereo plug connection is compatible with iPod, iPhone, iPad and MP3 players.
