Please pair your Freewire with your 10U headset. Specifically for the Shoei GT Air in my situation. It seems like it might be a simple firmware upgrade to achieve this. The 20S (which does pair) installs outside of the helmet creating wind noise. The integrated design of the 10U is far superior. While you're at it, please upgrade the 10U speakers to match that of the 20S. I know of at least a dozen riders who are waiting for this upgrade before they buy.
Thanks!
