Audio Spatialisation:
Music: good listening. I would say we are in the top slot of mp3 headphones. Not even at the entry level audiophile headphones of a great brand -that gamer- a helmet but it can be used to listen to music without frustrations. The bass is rich, accurate and do not saturate!
Dolby5.1 mode: Surprise! First, remember that the headset generates a kind of "sphere" in which the sound deteriorates a little, where a fairly strong echo is felt. Inside this virtual sphere, each sound source is perfectly and precisely located in space. To be honest, I did not even think that this is possible to obtain with only two transducers. If you push the vice to select the movie mode you will have the impression of playing in a cathedral, strange sensation at first but then very nice!
Fashion 7.1: 7.1 forget how it is cardboard. In this mode, the sphere I mentioned disappears completely, the sound is generally better -very close to its properties by listening to audio without echo but spatialization is totally lost. It was a kind of stereo expansion, pleasant to listen to, but blurred, which provides no position information. This helmet simulates well as Dolby 5.1. The 7.1 is strictly a marketing argument, it is just not functional.
Micro: with a specific hardware device, which isolates the voice of the rest of the environment, very effective. In excellent quality, the voice is perfectly clear, no extraneous sounds. Without exaggeration, it is of sufficient quality to submit an ESL match, and you must type in high prices for better.
Conclusions: Super Micro, cardboard of 7.1, 5.1 concrete. There. Spatial level, there are better if one goes to the 5.1 / 7.1 material at around 150-170 euros, as proposed by the TrittonMicro headset brand Pro + dolby digital 5.1 for PS3 / Xbox 360 / PC / Mac. At that price, and provided you have a good quality sound card, you must undoubtedly get an accurate spatial and without echoes. This particular model will please the budget, it costs 75 euros including postage, and has an excellent quality / price ratio.
