Sennheiser and Adidas have partnered up for a special version of their earphones. In all the models that were announced, they all feature a loudspeaker, and a volume controller built directly on the earphone cable. The cables are fiber-reinforced and remain flexible to temperatures as low as minus 10, according to Sennheiser.
All the earphones also feature different ergonomically designed ear pieces. For the MX 680 stereo model, Sennheiser has developed a patent-pending EarFin holding system, which they say will ensure that the earpieces fit and stay on your ear comfortably.
For the models launched, the prices range from $79.95 all the way up to $119.95, depending on what model you choose, of course. Adidas has also come out with a Nike Plus alternative, called the miCoach Pacer, which we covered two days ago.
