Just...Can't be bothered.
I bought a C4 nine months ago, and so far it's been a fairly bad experience. The schuberth reputation for quietness seems to have passed this helmet by, because the thing's unbearably loud at even regular road speeds (70-80km/h), and there's very few traces of German quality anywhere. Sure, it feels nice, and the visibility is great, but the original schuberth pinlock clone was worse than useless - it trapped fog on the inside between the pinlock and the visor, making it impossible to see anything, for long periods of time. Got that replaced with a genuine pinlock on the warranty. Great. Bought a SC1A, which worked reasonably well, at least if I was just using it with my phone, and nobody else. Unless I close the lid, or receive a small bump on the helmet(and I do mean small), or drove over a speedbump a little too quickly - then it just shuts off, and sometimes won't even start again. Apparently the solution is to have the wiring harness replaced. I can't say too much about the SC1A, except that I'm glad that I got it at a massive discount, since it's annoying to use, apparently has terrible range, and is based on outdated technology, that will most likely not be updated much (meanwhile Sena is happily updating their own units with all kinds of goodies, but refuse to do so with the schuberth units, until schuberth request it - that's on Sena though).
The greatest "screw you" has been schuberths response to all this though, see they just basically washed their hands of it, and released the C4 Pro, that supposedly fixes the problems. Even if it does, I'd be weary of buying one - schuberth don't seem to believe in fixing faults, leaving you high and dry if your very expensive new helmet turns out to be bad. Sure, you can pay to have it shipped to them, but it's unlikely they will do much with it, except tell you its structurally sound, and send it back to you. Too bad it's noisy as f..., and sorry we dumped the prices on your expensive helmet, and released a new version barely a year after putting it on the market(making my helmet close to worthless), but hey, you can always just throw more money at us, and buy the fixed version, instead of the failed beta version we originally sold you.
I didn't buy a schuberth helmet because they have great looks, graphics, or highest marks in safety tests, no, I bought it because it was supposed to be a reasonably safe helmet, that was very quiet (important to me), and I figured a big German brand like schuberth would stand behind their product, and not release a shoddy product, then not offer to fix it, then wash their hands of it. Customer loyalty? Who needs that? Pah. I'd recommend you stay away from schuberth, they certainly don't seem to give a damn. Too bad, I really wanted to like the helmet. :/
