i was looking for a new lid not so long ago,,,, and shuberth was my first choice,,,, untill i did some digging and found out about the sunvisor part.... (they may have changed it/made it better now)
but they have a moulding fault with the lens, and when you put one on and look through it and move your head side to side, you can sometimes get a vertical distortion that can REALLY put you off when you are riding as it makes a small area of your vision blurred.
the outside lens is ok, but the inside visor has the problem, and as that is one of the main extras of the lid, it was a big concern for me.
They are meant to be the quietest lids on the market,, but upon testing one,,,, i think my Arai is quieter,,,, personal choice probably.
plus i found for my head shape the Arai i now have was more comfortable.
I went to loads of shops and tried on loads of lids though,, and had them on in the shop for at least 10 mins, to make sure they werent too tight anywhere
