Hello to you all, I hesitated before buying this helmet because I have been disappointed many times by the sound quality of some much more expensive headphones. Very big surprise during the test; I like good sound with good bass fat and well pronounced acute and there I got an earful (this is the case to say). I tried to saturate the low and I did not succeed because the eardrums are not resistent !! At the level of comfort nothing wrong, the ears are wrapped and this helmet is not huge like some and, not much he does not use battery. By cons as stated in a comment a cover was not too much; but good for the price is already very good and as you'll understand I highly recommend this headset: great price / quality ratio.
