Walker's

Walker's makes hearing protection, and hearing protection is the range purchase with permanent consequences. Every centrefire firearm exceeds the threshold for immediate damage, the harm accumulates invisibly, and it does not come back. Walker's Razor series is probably the most common electronic muff on any American range.

Electronic protection is the meaningful upgrade over passive muffs, because it amplifies conversation and range commands while cutting the shot. That sounds like a convenience and is actually a safety feature — people keep amplified muffs on between strings instead of lifting them and forgetting. Walker's also make low-profile in-ear units, which is what you want under a rifle stock where a muff breaks your cheek weld.
