The sound, at least for gaming use, is excellent. The bass are not too present, just enough to make you really enjoy your games, and be totally immersed in the atmosphere of the game.
Even for the music, I was quite surprised with the clarity of sound. Well it is not a high-end headphones, but it's very very honorable for the price, especially compared to the headphones category.
I love having a cable to the short base (40 cm or something like that), which can then zoom in with an extension of several meters. This will not have a very long cable if you want just plug it into a device before us (for me the headphones are plugged in my microphone Blue Yeti in front of me, so no need for a long cable) or get out the extension if it is desired to connect the rear USB ports of their computer for example.
The remote control is also very convenient and allows quickly mute the microphone, and change the volume level. It may sound basic, but many helmets do not possess. In any case the remote control is effective and rather well placed at the wire (to understand easily accessible).
I do not personally use this microphone because I have a specialized micro side. Anyway I tested several times, and it turned out pretty good. Convenient to play or communicate, not really to make high quality voice you hear when taken as a bit of background noise, and the voice is not perfect like most headsets. The fact that retracts is certainly a big plus for me, it can store it if you have another micro at home and take it out when you go on LAN for example, or on any other occasion elsewhere.
It may hurt a little at first (especially if you wear glasses like me), but it takes a lot to wear the hours while the arches become loose and do your head. Honestly at first I thought it really hurt the ears, I was a little forced to wear it for several days, and finally now it does not make me any more harm. The hoops were well trained, and now I play several hours without feeling a single pain.
There are only two faults I can find him, the thread can not remove the helmet (for transportation, for example), and the fact that the helmet generally takes quite hot ears. These are really very small defects that can be found on a lot of helmets, so for me it's not really a problem.
