I love these headphones. Bought them 5 months ago in August '09 at REI. I think they are a great value for good sound and the all-important iPhone button that lets you answer calls, pause, and fast-forward. I could do without the volume control. I just replaced them using the REI 100% satisfaction guarantee, because the original pair developed a short-circuit near the jack, in the button circuit. When carrying the phone in a loose jacket pocket, the pause and fast-forward functions were out of control.
I hope this new pair lasts better, because I really like them. I might even buy a short extension cable, just so I can limit the short-circuit to that easily replaceable jack.
