[QUOTE="Krusty"] No guarantees they'll work for you obviously, or anyone else. For example my dad swears by the plastic mushroom type, but they're the absolute worst for me ears.[/QUOTE] 8< I've just googled and can't find them. <late breaking news> Ah, there they are. NRR of 33, I'll get a few pair and try them. As an aside, the law was changed this year to allow us to wear the foam type plugs. Previously, only the custom type were permitted. The ones I wear have a NRR of 32, 33 being the highest. The data is undoubtedly from a lab test and not indicative of RW use. But, I'll see what happens.
