Mitigated
Worked well for 7-8 months, then the RGB started to go berserk until it finally gave up the ghost 2 weeks later (cut itself off, flashed alone at night when the PC was switched off... in short). Sound-wise, it's pretty good, the sound insulation is pretty good for the price of the headset, and the microphone works well.
1 year after purchase, while the foam is still in good condition, the synthetic leather that covers the foam is crumbling (although this has been the case with all my helmets over time). Let's just say it held up well for the price.
So there you have it, without being exceptional, this helmet does the job in spite of a few problems.
