The headphones I use for several years now and find it class. The sound is great, they are very comfortable and you get by the sound around with not much. In addition, I save battery of my MP3 player, I have to turn up the volume by good quality nciht so hard to have a good sound result. Beautiful plus: If you get stuck somewhere, a small plug is pulled directly on the headset, so the cable is to be demolished for being protected. The fact that the cable is stitched (similar to an iron cable), it is almost impossible to get a cable break.
