Impact Sport Electronic Protective Earmuff – Hear more while protecting your hearing. Built-in microphones amplify low-level sounds such as conversations and range commands, while automatically reducing harmful noise. Features a comfortable padded headband, slimline folding design, audio input and 4-hour automatic shut-off.
The Impact Sport Electronic Protective Earmuff is designed to provide effective hearing protection while maintaining awareness of important surrounding sounds.
Built-in directional microphones amplify low-level ambient sounds, helping you hear conversations and range commands more clearly. When harmful impulse or continuous noise reaches the protection threshold, the electronic amplification automatically reduces the sound to help protect your hearing. Official Impact Sport documentation describes the amplification as being limited to a safe level and the protection as automatically responding to hazardous noise.
Its slimline design, soft padded headband and folding construction make it comfortable and practical for extended use and convenient storage.

SOUND AMPLIFICATION
The built-in microphones amplify low-level ambient sound, allowing important sounds such as:
Conversations
Range commands
Environmental sounds
to remain audible while the hearing protector provides protection against hazardous noise.
The Impact Sport system is designed to automatically reduce/attenuate amplification when harmful sound levels are detected.
PATENTED AIR-FLOW CONTROL TECHNOLOGY
The patented Air-Flow Control technology is designed to provide effective passive attenuation across a broad range of frequencies without requiring larger earcups.
This technology helps manage how sound reaches the ear and contributes to consistent attenuation performance.
