H/l Impact Sport Bolt Muff Grey

The Howard Leight Impact Sport Bolt Muff in Grey is a passive electronic hearing protection system designed to amplify ambient sound while providing impact protection for shooters, range safety officers, and tactical professionals. This earmuff leverages advanced sound amplification technology to enhance situational awareness during live-fire training and operations without requiring battery power when ambient noise levels remain below the activation threshold.

The Impact Sport Bolt Muff features strategically positioned microphones that deliver natural, directional hearing—critical for recognizing communication from team members, radio traffic, range commands, and environmental warnings. The advanced response technology automatically reverts the muff to passive hearing protection mode when noise levels reach 82 dB or above, instantly suppressing dangerous impulse noise (gunfire, impacts) while preserving the amplified ambient audio capability below that threshold. This dual-mode operation eliminates the need to remove hearing protection when situational awareness is required, then seamlessly protects hearing when rounds are downrange. Weighing 1.19 lbs with compact dimensions (5.5 x 4.5 x 8.05 inches), the grey finish option provides a neutral appearance suitable for both range and field environments.

This hearing protection system is optimized for shooters who require hands-free, passive amplification without batteries or electronics to maintain. Law enforcement academy instructors, firearms instructors, competitive shooters, and military personnel benefit from the ability to hear range commands, briefings, and teammate callouts while maintaining full impact protection. The Impact Sport Bolt Muff integrates seamlessly into hearing protection protocols for indoor and outdoor ranges, tactical training courses, and operational environments where communication and situational awareness cannot be compromised.
