For those who need this kind of helmet. I totally recommend. Very good investment. Quapness quality any ok
The sound is excellent for this price, the noise reduction is good, the external sounds are almost inaudible (the sound through the headphones is heard only at high volumes), the plastic is not very pleasant to look at, looks cheap but in general it does not matter. The ears themselves do not move around the axis unfortunately. Head from long socks does not hurt. LED lights bright green when working. EQ works well, sound changes markedly.
Result: the headphones are good, I recommend it. Cons concern only appearance.
