I just picked up a C4 Spark. I was in the market for a nice modular helmet, but I waited months and months for one of the C4 or C4/E1 variants to come on sale because I too feel that full retail price on these helmets (and I include all manufacturers' top-tier helmets here: Schuberth, Shoie, Aria, etc.) is insane—dạmned near $1k! Finally got one in my size and a color I could live with for 60% off at Revzilla. (There are nearly always nice helmets on sale - but invariably limited to sizes XS or XXXL or some-such). So when one came on sale in XL in red, I jumped on it. I was afraid the red might be a bit too orange from the pictures, but no, it's really very nice and matches up well with the red on my ATAS.
So far I like it a lot. I've only got a few hundred miles on it but it's very comfortable and quiet. I love the venting options - from subtle to more free flowing. I like the 'no frills" graphics, very cool-looking.
And I like that I can ride with the visor up at moderately higher speeds, 50 to 60 mph or more, comfortably. (Not the chin bar - I can do that too, but only up to 30 or 40 mph until it starts feeling a bit funky).
But the helmet really shines with the visor down. So, so quiet. Field of view, fantastic. Optical clarity, sweet. Nice flip-down sun visor too (the color/ shade doesn't put me off a bit). It's not stuffy, even in hot weather and with all the vents closed - which I find remarkable. The only vent I've been using much is the little one at the chin.
I came from open-face helmets for *years.* This is really my first foray into "full-face" (even though it's modular). I've tried on a ton of helmets at dealerships and found most of them gave me an intolerably constricted and claustrophobic feeling. Not this helmet.
My only complaint is the strap... it hits my Adam's apple when I swallow and sort of pinches just a bit at the top of my Adam's apple at all times. It has a nice piece of cushion there, but it's not enough. To make it work for longer trips, I will probably have to fashion some sort of solution - more cushioning, I'm guessing. I can see it being a problem on long trips unless I can figure it out. I hope I can, because otherwise, I really like the helmet... a lot.
And FYI - my head size is 23 1/2 in. (59.37 cm) (and probably your standard "intermediate oval" shape) and the size XL is a *perfect* fit. Not too tight, not too loose. It really couldn't fit my head any better. Got lucky there.
To your question about the comms and microphone placement... sorry, no experience there yet.
