That's almost four months I bought this product. I use it regularly on Skype or Teamspeak for conventional exchanges or video games. The microphone does not suffer any problem despite falls or blows hard times I simply saturate it to the sound of my friends (it's funny or it is not). The helmet itself holds well on the head, it can be adjusted in height to fit all.
The sound in the headset goes flawlessly, it is far from being in the high end, so do not expect to blow the bass in there or even subtly enjoy a classic piece, but the bet is completed and for the price this is by far a good deal.
