I wear foam earplugs(29-33db)-the kind you can pick up at any local drug store. I wear my headphones on top of them.
I've got to turn them up a little higher, but, it's still safer than cranking them up to hear over your own drums UNPROTECTED, which I suspect might be your problem.
I don't mind losing the high end because that's the most damaging, plus I'm used to the sound now...
I've got some high end loss in my left ear, so it's foam plugs for me...
