I have this helmet for almost 4 months and I must say he is bluffing in any circumstances :) the Sound is perfect for amateur and professional sound, it offers a frequency range that is perfectly rendered retail ready! comfort level can be worn 24/24 almost as foams are studied for an optimal comfort. The price is more than adequate and will replace almost certain brands of its general quality professional level / price. Not too serious nor too acute, this helmet not abrutira your ears if you like to play at a high volume.
