Good ear protection is a must at the shooting range, but it can be quite cumbersome. Earmuffs interfere with other headgear, but earplugs often fail to provide sufficient protection from the sound of gunfire. Fortunately, Surefire offers the best of both worlds in the EP3 Sonic Defender Double Flanged Earplugs. These are much more advanced than simple foam earplugs.
