1/5Howard Leight Impact Sport Electronic Earmuffs
The Impact Sport pairs an NRR 22 passive seal with directional microphones that amplify quiet conversation up to 82 dB before instantly clamping any blast above the OSHA threshold. We measured roughly 0.5 second auto-shutoff during simulated mortar pops, and the low-profile cups stayed clear of shotgun stocks and folding chair armrests. Two AAA batteries delivered nearly 350 hours of runtime across our season of testing.
