Works exactly as hoped..., January 4, 2012

Like the reviewer preceding, at first I was also frustrated that my headphone cord was still sliding through the wire holder as I moved. Then a burning bush spoke to me: "Turn thy wire holder perpendicular to the direction that the wire is running between your headphones and your audio device!"DOH!!! I heeded the burning bush, and was rewarded with no more troubles forevermore...praise Jeee-sus!Seriously, it's a very simple matter...the top part of this device which holds the wire, rotates. All you need to do is rotate it so that the headphone wire flow is blocked by this perpendicular positioning. Ta-da! No more complaints.My only quibble with this clip is that it's a bit overpriced for what it is, a tiny cheap little plastic device that was probably made for 10 cents in some Third World sweatshop and will probably not last more than a year or so if that. $2-3 seems like a more reasonable price, especially if sold in a multi-pack. Oh well,...

The button isn't spring loaded so it doesn't hold the cord in nearly as well as it should. Really doesn't do what it's advertised to do. Probably need to pass this one over.

Doesn't hold. Bought it as replacement for original clip that came with headset, but this one does not hold firm to the headset cord. The device "attaches" in two places. One clip is the alligator clip that attaches to your shirt, and that clip is great, works perfectly. But the part where the clip attaches to the headset cord is not strong enough to hold firmly to the cord. As a result, the headset cord slides throught the clip and the weight of the cord pulls the headset tight on your head, which is what the clip is supposed to prevent in the first place.So IMO, absolutely worthless, as is. In order to get it to function, made one wrap of tape around the phone cord at the spot I wanted the clip to stay, then reverse wraped the tape so it stuck to itself with the sticky side out. Now the clip would actually grab. Not the end of the world and more trouble then it was worth to send back, so I didn't bother. But annoying that it didn't function out of the box.
