First of all I would like to commend the great service of Amazon and the following reason: I ordered for the headphone's bedroom. Quick connect ... all great, but then! The second use is constantly interrupted connection away and settled only by separating the transmitter from the media restore only to break away again after 2-3 minutes. A call to Amazon and the replacement reached me after a few days. The new set currently functioning properly. I hope it stays that way.
For the quality of the headphones: are quite good for this price. Sit comfortably, do not press, listening to loud when they rushing but significant. But as I said ... Ok for this price. Following update again if problems occur.
Once again a big thank you to the great support from Amazon and the very helpful service staff on the phone.
