dan, you should look into one of two options....some custom-made earplugs (go to an audiologist to get these), or get some Hearos HiFi earplugs (that's what i use....they're made by Etymotic Research, one of the main companies that make the custom plugs, and they're basically the next best thing. they use the exact same filters as the custom plugs, they're just not custom fit to your ears). the filters they use cut all frequencies much more evenly than the cheap foam plugs, and they bring the lows down as well. the lows that you still hear with foam plugs can still do a lot of damage, and the good earplugs help prevent that. you can get the Hearos HiFi plugs for about $15 per pair at guitar center, and i highly recommend them. sound much better than foam plugs, you can still hear everything really well.
