Thank you for taking the trouble to run the tests. I've been driving the C4 (without PRO) for 6 years and I'm not convinced by the C4 and certainly not by the interior noise. For the practical test: a) the temperature measurement would have made more sense in summer temperatures b) a noise measurement behind the windshield of a BMW? Partially shut down or not, I would have expected a 'naked bike'. So that the helmet gets the wind properly. The reaction of the driver when turning his head when the helmet is in the wind would also be interesting. c) aging. Unfortunately you can't test this, but my C4 now has a gap of about 2mm when it's folded down. You can move the chin piece back and forth with your hand when it is closed.
habe jahrelang den C3 gefahren dann kam der hochgeprisene C4 (noch leiser besser Airodynamik und und und) Da mir der c3 zu laut war wechselte ich auf den C4pro inkl.SC1 .Schade um das Geld ,(C4 war kein Tick leiser). So wird es mit dem C5 wahrscheinlich auch sein. Und ganz negativ finde ich das das SC1 bei einem wechsel nicht übernommen werden kann
Toller Vergleich, der viel Rennerei erspart- danke!!!

Neues Fahrzeug und der C4 Pro heult wie eine Handsirene... der alte C3 ist da unempfindlich.
guten Review
Helm Weight is not all... Better Aero and low noise are could’ve compensated the higher weight.
Weight from ECE22.06 helmets seems to be in general higher than ECE22.05.
That is correct
Wir reden hier von einem 1000€ Helm 🙈
