I have had my Carbon S1 for 18 months and I guess I must have been lucky or it just fits better - I would buy another tomorrow if I needed another helmet.
Very quiet - replaced original visor because of peeling after 2 weeks, new one has lasted since with no problems - Drop down sun visor works a treat - have Autocom fitted ear speakers fitted - if it ever mists up I just open it a crack and it sorts itself out within a few seconds without any leaks - did I say how quiet!!
I have a J1 for really hot weather but prefer the S1.
Hope this helps...
