Very good helmet
Nothing to say about the quality of the sound, it's perfect. The high-medium-low balance is very well conceived, which restores the music in its totality (I do not like headphones with bass-boost...) Bonus point for the sound adjustment wheel which is satisfying as possible ?
The microphone is very pleasant to use, and cuts external sounds very well.
I found the headset spring a bit hard at first, but after a few hours of use it became very comfortable.
