Bitfenix has chosen his partner to outsource the manufacture of these helmets. Defects here? rigor micro boom that not even trim level than the rest (although I must say that in general I do not like the microphones helmets ...) and that put the volume on the cut mini remote control the sound in one ear but is left in another (sound balancing himself again when we go back the sound a little strange, my fault model?). Coming from a Siberia V2 I prefer this one!
