Perhaps someone has something that works, but my "testing" of a couple models from Astra and AudioTechnica didn't fare so well. http://www.arcmics.com/...essories/throat-mics Coupled with motorola systems for air to air haven't worked. Nor did the Stryker system.
Everyone that has been using them at our DZ either has a G2 or a G3 so I'm not sure if the noise inside of other helmets could cause issues. But if you are fairly close (within 1000ft or so) they work pretty well. I've been able to talk while flocking and freeflying. I know people that have used them in the tunnel but when I tried flying head up there was too much wind noise coming in the bottom of my G2, maybe they would be good for belly. I put one of the speakers behind my audible so I can hear it really well. It does sacrifice some of the sound from that speaker but I'd rather hear my audible.
They are designed for MC so they put up with moisture well, at least so far.
Plus you can pair them with your phone and listen to music on the way up.
scala g4 headset works great for long range on motorcycles. open or closed faced helmets too. I've used the Q2 and the G4 on long street rides with up to 4 other motorcycles intercomed in. They just came out with the G9 not too long ago that is supposed to be even better.http://www.cardosystems.com/scala-rider/scala-rider-g9-powerset

What about motorcycle intercom systems operating on bluetooth? Seems like they might already be optimized for a little wind noise and installation in a helmet?
Presumably Bluetooth range is too small. No problem for a bike rider and pillion passenger, but not much use over longer distances.
The range won't work, and more than that, the winds come from different directions. Throat mics _should_ be the best answer. We also worked with chatterbox systems, they don't work any better than the system we ended up building. Additionally, be aware that what works in the tunnel doesn't always translate well to the air (and vice versa). It's a different wind direction.
