The helmet proved a good fit on the 1763 mile trip to the Czech MotoGP and back. The noise was no worse than my Shoei.
The bluetooth was easy to setup but at anything above 70mph not a lot of good.
The volume simply isn't loud enough to work with a combination of wind noise and ear plugs.
With them out and testing the controls the systems own voice is pretty good.
It's a shame as the main selling point of this kind of helmet is the bluetooth. Otherwise you may as well buy an alternative make or their own much cheaper model.
Still a decent helmet but can't say I am not a little disappointed.
