Great running headphones, however...,
This review is from: Sennheiser PMX 680i Rugged Neckband Headset with Integrated Remote and Mic (Electronics)
... they are not quite as described in the product description. The cable is actually not adjustable at all. The integrated volume controller (which includes play/pause/skip functions for iDevices) is not detachable, so the cable will always be of a fixed length. A clip to fasten the wire to your clothing does help to manage excessive cord length, but a detachable unit would have been a lot better for people who run with their music player strapped to their arm or in a high pocket.
Excusing that fact, these are great headphones for people who run outdoors. The open design doesn't cancel external noise and the back of the band has a reflective strip (both handy safety features). The fact that the cord only joins to the headband on one side prevents a lot of hassle with wire kinks and tangles, and for me, the fit is stable and secure.
