This helmet has revolutionized my car trips and plane. I useful daily. It's comfortable and it filters all the annoying noise (purring engine, wind ...). It just keeps what one wants to hear, ie non-repetitive noise: music of course, but also the occasional sounds of traffic, useful for driving, when someone speaks .. . Once you put the helmet on, it seems that the volume has been increased, it is very surprising !! But it is simply the effect of the filter, which makes better highlight the music by removing unwanted noise. It is a helmet that gave me for Christmas last year. I recommend it to all. A buy eyes closed !!!!
