despite its poor very effective noise reduction

Without activation of the "noise reduction" sound is poor too saturated serious. I already have a seinheiser a marshal, an AKG. They have no noise reduction. Compared with these models, the sound of the audiotechnika sucks worse than that of Marshall that is to say. So the effectiveness of the noise reduction is not enough to make me love this helmet.

I returned the item and I think acquire Boss.
