At first I was afraid to buy a helmet, this helmet especially because very testing may or comments are findable on the net (at least in French). I chose the one because he was returning in my budget, has its "Dolby 7.1 and has a look that I like :) The sound Dobly be enabled / disabled from a button on the left earphone (which is a pretty blue light is activated when the 7.1) and a "roulette" to increase / decrease the sound, and another button to turn off the micro is dailleurs good (microphone). I use this headset for playing video games, listening to music, videos and I commented. So I had absolutely a headset with a minimum of quality at a lower price. This one is perfect. After 1 whole day spent testing the (yes, big geek), I hardly felt NO pain in the ears. It covers the ears, do not support it (as he circles). By cons it is not airtight: means what happens around us and vice versa. Dolby 7.1 looks pretty, you feel in any case a difference when going from Stereo to 7.1 (by pressing the button). It is very comfortable with the foam that covers the ear and the top of the head, and is more imposing than the pictures (at least for me, who have never had before helmets). It has a long thread (2 mêtres) who connected to the PC via USB, and comes with a very easy to use software (even too much: there are only 2 or 3 Possible settings). In short, I recommend this helmet for anyone looking for quality at a low cost. Do not hesitate!
