I got some Earmolds from the Sydney Motorcycle Show last Friday. I've used them a few times on my bike, and I'm not sure they fit properly. They seem to wiggle their way out of my ears slightly, and if I move my jaw around (which some how moves my ears) I can feel them moving around, blocking out the noise, then not blocking out noise. So I wanted to know how yours fit? I've read over the instructions of how to fit them properly, so I don't think that's the problem. Any ideas?
