Query: Great for Running

These headphones are well thought out and are the best I've found for running. The behind the neck design allows you to wear a hat while you run and the single cord seems custom designed for runners - especially if you run with your MP3 player attached to your waistband. The cord has a short straight section near the pin, then a clip, and then a long coiled section. The result is that you can run the uncoiled section from your MP3 player around your back at the waist then clip it there. This allows the coiled section to be positioned securely directly below the headphone it is attached to.
