Now for the characteristics of the helmet. The finishes are very successful, large compfort. I, who have big ears, you get used to very quickly. The hoop that fits directly without setting against all odds a great addition that works. It can run with the headphones without problems but attention can be the gnashing that can occur when running. Magic, one has no idea how to pass the sound of a listener to another! No wire, it's just boulversant to see! One thing more breathtaking is the insulation of sound. It was nice to put a light in his background, we hear perfectly. It's just awesome, but be careful when traveling together, we will not hear anything, it can be dangerous (but what's good!). The headset can hold slightly warm, but I used it for about two hours without any real discomfort.
For all the songs where the voice is highlighted, this headset button perfection. With its isolation, we are immersed in the song. I could therefore vibrate discovering the nooks of a song that I thought yet know by heart.
For all the songs with deep bass. This helmet is alas not made for that. This is one of my great regret I who love the rhythms. Serious and deep sounds are not exceptional. They are simply "normal". You do not lose audio quality but we have not this side "magic" that takes us when we listen to any other music. The sound is just the same as what we have previously heard. A except that the insulation gives still more.
If I had to rate the songs with headphones for normal tones and treble I give a 9/10, a 6/10 held out for serious tones (the helmet does nothing more really). We regret some headphones that can give us the impression of warm ears after two hours of listening.
