I got Sennheiser PMX 680, co-branded w/ Adidas, neckband type headphones. However, I prefer the Sennheiser PX 100-II's, that I got at the same time, better for sound, although they're not as good for staying in place while exercising. So - anyone want the 680's? Make me an offer, they're new, I put about thirty minutes of use on them, still have the packaging.
