I knew that the headphones squeezed poor qualiter but the sound was acceptable. Only, as I am handyman on board, I order just to have a jack 3 points, yarn, and microphone. When I cut the son, I noticed that he was walking interrieur, over the jack at this time full of super glue to paste the sheath literally pull the plug (the only son Driver is held), has become dirty. The son walks to enter speaker and even to output. There has every chance for everything after a hard month. I do not rachèterais this pair, and I will not recommend.
