The concerns that I have met residents at the headset itself which, at first, very strong greenhouse. For several weeks I could not wear it for more than an hour because it really hurt. And the fact of wearing glasses does nothing to the problem, on the contrary. It took a month for the helmet loosens force to put and remove it to make it better. Still, if you play video games enormously (around 2-3 hours per day), the use of the helmet is not recommended because of the atria that crush the ears after several hours, which prefer helmets atria envelop everything (like the Razer Carcharias I bought just after).
Unfortunately, another problem occurred just after: micro passed away after only one month of use. Already at the beginning, it was common to have bad contacts when I plugged. It was not until I force a little hand to the microphone works. The quality is pretty average. But by removing / reconnecting the microphone eventually stop working ... No luck, I use the microphone very often to play online.
A shame, because the sound is very good for a headset of this price. Recommended for people who play and use the micro occasionally and who do not wear glasses!
