Modular helmets are a some of this, some of that type thing. Mine is a bit close too. Normally I just smear some toothpaste on the foam and that way my teeth are pre-brushed. :joke:.
Some other units are available, but I never found them satisfactory either, especially as in town and in slow traffic when using the CB , 99 percent of the time my flip up is flipped up. As we talk the most when going slow, in town and so on, the units that have the mic mounted in the flip, I did not like them either. So I just use the J and M, and simply move it out of my way, wiggle my nose or push it out of the way some way. Position it so it does not bug me. It will even pick up and work well positioned under your chin. Does not have to be right next to your mouth. If not using the CB I just pull it down out of the way and ignore it.
Yep mine is a bit close , but got used to it.
