Peltors, ProEars or Howard Leight .... Electronic-Noise Canceling w/ volume control.
If you’re shooting handguns, except for something bigger than .45, then just the ear muffs will suffice.
If you’re shooting bigger than .45 or AR15-AK-or bigger, than I suggest some ‘foamies’ in your ears and then the muffs. Years of being a tough guy and not needing that added layer of noise cancellation have left me a bit hard of hearing.
My 2cents.....
Yep, I love being able to hear range commands clearly. I just wish the manufacturers would find a better way to arrange the battery compartments. I've lost two of the Peltor 6S Tactical slimline muffs due to battery leakage. Put the batteries up on the spring band, or elsewhere that they're easily accessible.
double up if you’re shooting indoors
