The helmet of any of the characteristic of a mid-range gaming headset volume control, microphone button, materials suitable for prolonged use etc. Audio / mic in good order. more than sufficient for games in stereo. For games or sound spatialization is greater, (typically FPS) opt for a 5.1 headset, even emulated, it is really worth.
I went from a corsair vengeance 1300 to it, that I took while waiting to find a new high-end headphones that I like. I specify this because the criticism that followed, I think are greatly related to the range change.
The lead of the headset with the rubber boot is really ugly ... The braided cables are more aesthetic, and more reliable.
Plastic, without being fragile, is really "cheap". A black plastic, hard plastic makes a good noise.
Finally, I have a big head (62 cm diameter) and helmet use it. It's just I think the design of the upper, very flexible. Moss cushion well, but I'm still tight.
Voila. I plainds, but I think at that price, an average head is a risk free purchase.
