I too bought the C3 and SRC from Helmet City last week, and also received the £50 discount for the SRC due to purchasing together.
I'm still testing and had high expectations (for the price), but first impressions on the SRC are that the radio reception is poor and constantly crackling, at least here in London, to the point I'm about to stop tuning in! The other functions all work very well as per the manual. The buttons take some getting use to and are a little difficult to feel and locate under gloves, particularly the volume and tuning buttons which are nearly at the back of your head way behind your left ear - you got to stretch your arm to locate and press them, though I'm not sure how else you could make this better on a collar system.
I also bought a seperate sony TMR-BT10 bluetooth adapter pluged into my speed camera detector, Novus Rider - while this works when paired, you cannot listen to another input (radio) and have the novus alerts interrupt the radio, so I am still wearing the earpiece for the Novus on top of the SRC built in speakers. I have asked Schuberth to confirm if this is possible now or with a future download update.
Also, just so you all know, the schuberth SRC is made by Cardo who make the new Rider G4. The two systems are almost identical (you can download the manuals from eachs respective website and they are nearly identical verbatim). The difference, apart from the collar fitting the schuberth, is the G4 can pair 4 riders in intercom mode versus 3 on the SRC. Also, the G4 has a pop-up antenna which extends the intercom range to 1 mile, while the schuberth can only manage 300m. The G4 is £240 and SRC is £299, though if bought with the helmet at Helmetcity they will discount £50, and give you a free T shirt, visor waist bag, cleaner and cloth, but best of all a free luxary helmet bag - its really good!.
Martin at Helmet City was really helpfull and even gave me a free cargo net and helped me fix all the goodies to my bike, and protected with loads of bubble wrap - top service, and the shop is worth a visit.
As far as the helmet, well its really surprising how much noise it actually filters out while still being able to hear the outside. The visor works really well and stops at all the notches without falling down when going over a bump (aparently a problem with the original C3). When down in the 'city' position nearly all noise damping ocurs, and if you push all the way to close the tiny gap from city position it further eliminates noise. Its also important to ensure the chin collar is properly in place for the noise surpression to work really well.
Ventillation through the top intake has 3 settings and you can really feel the air flowing when fully open - likewise with the mouth air inlet (2 positions). and when open no fogging ocurs even at traffic lights, thanks to the pin lock double visor system. My glasses do however steam up a little so i've just ordered some Clarity Defog It. The internal sun visor is a godsend meaning I dont have to carry my sunglasses in addition to my normal glasses to avoid the morning glare - this stays in whatever position you set it at (another issue with the original C3) - the only issue here is with the outer visor down along with the inner sun visor down, air circulates with more difficulty and so my glasses fog up even easier (hope the Fog It comes soon!).
All in all, the quality is right on with everything fitting tightly and with no surplus movement - it feels really solid. The cheek, chin and head linings come out to let you wash them.
I too was originally hoping someone would review the BMW system 6 against the C3, and found only one person on a spanish forum who basically thought the BMW was a slightly different and lesser C3. It dosnt make sense to me how BMW could have the same helmet and charge £100 less and still make a profit - They must have cut corners to be able to achieve this saving, so I went with the C3. Also, it appears the SRC collar will not fit the bmw lid, and at the BMW dealer 2 weeks ago the service guy said they had received specific bulletins confirming the collar will not fit - it also explains why they are pushing their own bluetooth system which has much less functionality than the SRC or G4.
Hope this helps
but will try to get out and about with it tomorrow and will post a short review.
