I've been a long time Shoei wearer, having had several X-series and RF-series going way back, ending up with Neotec, and lastly GT-Air, which I still wear regularly. A few years ago, when it came time to replace the Neotec, I didn't like Neotec II's built-in proprietary intecom, since I already have ones I like. Spending several hundred more just doesn't sit well with me. So I jumped ship and bought a Schuberth C4 Basic, which is the exact same helmet as C4 Pro, except without the built-in intercom. If Shoei offered the same with the Neotec II, I would've stayed with Shoei.
In any case, I like the C4 Basic a lot. Ventilation is as good as the Shoei Neotec. visor and built-in sunshade both worked well. Fit was generally good for my round non-oval head, except... the infamous Schuberth forehead. I had read up about it and test-wore the helmet in the store for a good 15-20-min, far longer than any other helmet I've tried. I thought I did my due diligence to make sure I wouldn't be afflicted by the Schuberth forehead.
Well... very first ride with it, my forehead started to hurt after about 45-50mins. I tried the spoon trick to get a bit more forehead clearance. Didn't work. Tried shifting the helmet around periodically to relieve the pressure. Nope.
So now, I have resigned to using the C4 basic as a commute helmet. Even then, it is kinda iffy in the afternoon, which can easily get into the 45-50min danger zone. Kinda sad to say, but I won't be buying another Schuberth again.
If you plan on buying a Schuberth, make sure you test wear it for as long as possible. Even then, best to buy it at a store that offers return and/or exchange for another helmet.
