Going thru posts about sound/comms systems leaves me with questions I know you all can answer! I use a modular sled helmet. I have tried a couple different ear buds and not happy with that. Sled and wind noise makes me have the volume too high. Looks like Cardo would be the way to go but don't really care about the comms part. Do the supplied speakers fit in any helmet? Do any of you use this while snowmobiling? Options I don't know about? Thanks in advance
