Battery will last about 5 hours constant music playback and is not bothered by rain, only problem with these are the speakers are crap. Thats a easy fix though
5 hours wouldn't make it through half of a ride where I think I'd need a com system. That's a pretty huge problem imo.
Sena makes some awesome headsets, from what I've been told the batteries go 10+ hours, they're sleek, have good speakers, and are easy to use.
I've got some chatterboxes that are awesome too, but the speakers have no bass. They have a feature that I can't find on any other helmet-mounted unit, but I really like. A push-to-talk button. VOX is nice, but it can be a pain in the butt, especially if you're riding with someone who likes to sing along with their music. They're pretty expensive though.
I've also heard some good things about the hand-held type systems that clip to your belt. Biggest problem there is the wires, but those are easy to sort out. They tend to have pretty good range and battery life as well.
