When I opened the shell, I find myself faced with the product packaging. It y'avait Chinese signs, which made me very hesitant and doubtful, but when OMG I saw the logo, I knew that it was a quality product. In addition, the package was really very impressive hat. They also added a CD that I did not need. I just plug the USB cable into your computer and voila everything works. At the beginning when I put music, I was going to explode the head, these headphones are very powerful. So be careful to reduce the sound level to 1, that is what I use now is perfect.
