Interesting. They must vary in different helmets. Mine is in a Caberg Rhyno. Nobody can understand my calls at speed, I have to slow right down.
I have the Scala Rider G4 and agree with the comments above (works great). I tried a number of built in helmets, was not happy with the quality. Returned all of them. Got another Arai (always had one) and it is hard to have a cheaper one (quality). If you can find a quiet helmet and get an add on communication, great way to go, of course you end up with a helmet that costs $800 with the equipent in it, which I carry with me like a purse :blahblah: but I'm very happy with it.
Here is the review I wrote back in March on Revzilla's site (not bad prices)

Comments:A review of Scala Rider G4 - I have used this product for 10 hours and am very pleased. This unit has the most functionality out of any I have researched and used, period, and there were many for the past 8 months. Seperate units, those installed in the helmets, and this out performs them all. The auto volume adjustment is very nice in stop and go traffic, no music blasting your ears when sitting at a light after running 65mph. Voice command answer for phone calls was great. Of course the faster you go, the more noise you have in your helmet. As a result, those with windshields will always benefit by not having to turn the volume up as much as those without. Speakers have plenty of power, mounting was easy and speakers were placed under the pull over material covering the inside of the helmet (very thin material). Try to get the speakers close to your ears, not because they are not loud enough (they are) but to cut down on the noise you receive normally riding with the helmet at highway speeds. I mounted this under the material to avoid my ears from pulling at the speakers when putting the helmet on. Controls are a bit fim to press, I imagine they will soften with use (and I plan to). Pairing was simple and phones with voice commands will benefit (make sure you understand how to use your voice commands from the phone since this can be a tricky under normal use). If you have a phone that receives e-mail and text, turn off alerts with the exception of phone calls (if you have this function) to avoid disruption during media play. I have not used the FM function at this time. All media was provided via bluetooth from my phone. If you have any specific questions, please post here, more than happy to help based on my experience. The only Con was how long it took for the product to come out, however, it was worth the wait. Do your research and compare functionality to others. As of today, this is the one and all the others are way behind. Besides, you can use your preferred brand of helmet instead of using a cheaper version simply since it has some phone capabilities (I almost made this mistake) and was not satisfied with the quality of the helmets. Easy riding all and I hope this helps."
I have a few thousand miles on this now and am still very happy. :blahblah:
A final comment, with the install, make sure your earphones are against your ears, seems obvious, but makes a huge difference, and mic placement is also important. I have my ear phones installed under my material in the helmet on top of the padding. Added some extra padding under the phones to raise them to my ears. Arai Profie is the helmet. Let me know if you have any questions. (And the charge really does last 8 - 10 hours, long enough for a full day and quick charge for the next).
