Because of federal law, just about any earmuff-style hearing protector will be sufficient. Just get the best you can afford.
My wife and I use earmuffs we bought at our local hardware-and-lumber-yard. I didn't look at the brand name; I was interested only in the attenuation figures, and all the muffs they had for sale were about the same in that department, regardless of price.
Higher price brings somewhat greater comfort. It can also bring electronic amplification with a sharp cutoff, so you can hear people talking in normal voices until a loud noise intrudes and the electronics automatically shut down for an instant to protect you.
I still occasionally use disposable foam earplugs, because they're convenient. They work well for me, especially for rifle practice.
However I have suffered some hearing loss from a couple of hours of shooting with no protection at all, many years ago, so I'm not the one to advise on this particular subject.
Except to say, "Always use hearing protection!"
