The sound is very good, very well mean greasy to 7.0, a pity that the pressure of the helmet is not strong enough to prevent gaps that may just make us hear outside sounds. The microphone also works perfectly sound rendering of the voice is very good, against damage by the microphone after having been shot several times its base, it is no longer possible to keep it in the air and it falls in the neck. The keys to adjust the volume, enable / disable the microphone works well, but this flaw is that personal touch ... for the microphone there is no indication allowing us to know if it is enabled or disable.
I recommend this Micro-headset, but for those who started in the gaming and computing.
