OK, it's obvious that a grunch of you have purchased the C3. I had one of the first Schuberth's many years ago and I recall it was kind of noisy.
I've been happy with Arai Quantums for a while, even field tested one, ouch!
I tried on a C3 last week at the dealer and was impressed with the fit.
My question, is the new C3 comparably quiet as a well fitting Arai?
