I used this helmet on a trip to the antipodes (New Zealand, 2x12h one way), light it and forget the noise reduction is incredible (well take the right size for headphones, you have three available in the box), the sound of the engine has been totally eliminated.
Even without music it allowed me to sleep peacefully
But beware, the headset is very lightweight and can easily be forgotten, during a movement I broke the jack, supporting me the replaced immediately.
