Bluetooth Earmuff Nrr21 Odgrnhoward Leight Impact Sport

The Howard Leight Impact Sport Bluetooth electronic earmuffs deliver professional-grade hearing protection with wireless connectivity for the modern shooter. Built around a 21 dB Noise Reduction Rating, these active earmuffs combine traditional passive protection with smart sound management—amplifying safe ambient sounds while instantly shutting down harmful noise the moment gunfire hits. Whether you're running drills at the range, hunting in the field, or working around the shop, Impact Sport keeps your ears safe without cutting you off from what matters.

The real standout is the speed: a 0.5 millisecond reaction time means the compression circuits kill the noise spike before it reaches your ears. Paired with Bluetooth 5.0, you can stream commands, music, or podcasts from your phone or headset without removing the muffs. The dual omni-directional microphones amplify ambient sound up to 5X normal levels, letting you hear a hunting partner's whisper or a vehicle approaching downrange. Separate volume controls let you dial in the external environment independently of your Bluetooth feed—so you stay aware of your surroundings while staying connected.

The Impact Sport is built for practicality. AIR FLOW CONTROL engineering gives you a low-profile ear cup design that won't interfere with rifle or shotgun stock positioning. It folds compactly for pack or range bag storage, runs on a rechargeable lithium-ion battery with a USB-C cable, and auto-shuts off after 4 hours of inactivity. An adjustable headband now comes in two sizes for a secure, custom fit.
