Pro Ears are great, especially if you wear hearing aids. I know the guys that invented them.
Dillon also makes a great set and so does Peltor.
Muffs are the way to go. You can hear the conversations around you, the range commands and the timer with no problem. You can also hear your hits on steel targets. You can't always do that with plugs.
I've never lost my muffs during a run and gun stage, even when I was 100 lbs lighter and much faster.
