Ordered a set from Rocketmoto and finally got a chance to try them out. First off, I'm in a Shoei X-11 and the speakers are too fat. Putting the helmet on and taking it off was torture, but once on it was fine. Tried a few phone calls which worked fine and piping in music from the iPod worked great.
Overall very happy with the set, but I need to figure out a solution for the speaker thickness. I'm going to order the earbud bracket when available.
