You don't have to spend a lot on electronic muffs to get good ones, either. This is what I have and they're fine. I can attest to highly directional sound, as that is one of the fears of buying "cheap" ones.
E-muffs I am also a big fan of .45 ACP-lucky me, since it is low-pressure and generally places rather low on the big boomer's list. All good for somebody that suffers with tinnitus as a constant companion. Oh, I've been a good boy for over 30 years-not so much before that. Too late, but I'd kind of like to keep what I've got left.
