Audio quality: Nothing fancy, comfortable in the game, less music, treble / mid appear flattened ... Lower strong enough, while remaining not exaggerated (like other headsets or they are too often amplified my taste). For the price, it deserves 4/5.
Quality microphone: A priori, nothing to report, 5/5 for a little demanding use (to see if we look for a good recording quality)
Ergonomics: Helmet pleasant, slightly open (not totally isolated from the outside). Very comfortable to wear, quite sober design. Cable 3m = good point, but at that price, no "mute" button or volume on the cable.
In short, for gamers who want a headset without spending half a hundred euros, this helmet does very well his office, I recommend it.
