This is my first helmet all and I love it though it is not without fault. At waist level, with a fair bit larger foams that have been more suited to my ears. Noise reduction is effective but do not expect miracles, loud noises and especially his little serious mitigated. When I turn the TV that behind me and I turn just noise without putting his I hear. But once I put the sound in the headphones I hear and I am no longer in my little bubble. By cons where I took a slap is when I heard (and seen) a movie with this headset, I had the impression BE cinema. Low immerses us completely in the film, the sound very clear ways not need to put the strong to his full advantage of the soundtrack of a movie. Level music that makes it too but I was less than impressed when watching a movie. Personally I put it 5 stars well deserved.
