So the headphones had to unpack and test the same, was equally satisfied with them, with full batteries have with me a range of over 10 meters and even goes through the wall without noise !!! At the sound one can even say anything, because that is exactly the same as the top design, no Ehlen ended adjust the headphones on your ears, because they are equipped with an elastic and adapt very well by the head and the ears. So in the short a good investment and I can not complain so far !!!
