I use ear plugs with my 35dB ear-muffs at the range. Blocks out almost everything.

Hunting, admittedly, I don't use any hearing protection, unless you count my hat which has ear flaps to keep my ears warm which do deaden a little sound. If I hunted with a rifle that had a muzzlebreak I would.

I hear the Walkers Game Ears are a good product. I don't use them because they are a bit expensive, they require batteries which will, with my luck, go dead 30mins after I get settled into the stand 2 miles from the truck and I'll have forgot to put spares in my pocket, or one would fall out of my ear when it was dark and I wouldn't be able to find it. Just one more thing to forget, lose or break. I used to carry a bunch of gear into the field, but I've since decided that traveling light and keeping it simple is the way to go for me.
