Nearly Perfect
I purchased this clip because all the clips I currently have that came with my headphones have broken. I was looking for something with a different design that might last at least as long as the headphones. As many have already mentioned. the hole in the clip is too big for most healphone cords. I easily solved that issue with a small piece of duct tape wrapped around the cord, between the clip and the headphones. I've been on a few 3-hour runs with the new clip and I've had no problems with it. Out of the box I'd rate it a 4 star product. With some tweaking - 5 stars.
