I've heard, nope scratch that... I can't hear anymore, anyway Walkers Game Ear is supposed to be pretty good.
I get hearing tests every year at work, and it is always getting worse! I wear hearing protection at work, working with power tools, and at the gun range, I have not mastered wearing hearing protection while hunting though!
I just can't hear game or myself, if I'm making too much noise, so I haven't worn protection while hunting. If you find something that works, post it so we'll all know about it!
I just got a pair of muffs again for the shooting range, and I don't like them! (and if you don't like them, or they are uncomfortable, you ain't gonna wear 'em!)
They hit against the stocks of my rifles, and throw me off. So for the time being, the best I've found are the foam inserts. The db. rating on most of the inserts are higher than on the muffs, with less weight and bulk! Good luck!
