These headphones are optically and acoustically just great. The on-ear system has worked wonderfully for me and I thought I had finally "perfect" headphones found: Super sound, noise-free, comfortable to wear. The drawback of this headset is the cable. It is specially rubberized. Sounds like first great, but it drives a mad, because it gets tangled up churning out (and I'm doing so that no unusual sport exercises!). I'm always annoyed when I have to invest more time to Enttücken. By frequent unraveling, the cable is broken quite quickly. For me the first time after about 13 months. Okay, was warranty, have directly get a new one. The new has held back only 14 months. Now I can no longer exchange, because the 2 year warranty has expired ... Somehow I do not see a year to buy a new pair of headphones, because up to the cable, no traces of wear and tear or other damage are otherwise seen. I wish as improving these on-ear headphones with another cable that can be wound, for example.
