3M Single-Ended Combat Arms Military Ear Plugs - Generation 4 (NRR 7/23)

3M Combat Arms Technical Brochure Combat Arms Generation 4 Tactical Military Shooter's Ear Plugs offer a revolutionary step forward in shooter's hearing protection products. Combat Arms Gen 4 shooter's ear plugs provide user-selectable protection in a single low-profile pair of ear defenders that let you switch easily from regular NRR 23 protection to NRR 7 variable noise protection. The NRR 23 mode blocks out constant background noise, while the NRR 7 mode allows for situational awareness plus instantaneous protection from sudden, hazardous impulse noise. Switch modes without the need to remove the ear plugs from the ear: each Combat Arms Gen 4 ear plug is equipped with a toggle valve that is easily operated by touch while in the ear. Variable Protection: Toggle Between Two Modes With Combat Arms, there is no need to switch to a different pair of ear plugs to change the way your hearing protection operates. Now you can simply touch a toggle valve to close a vent inside each ear plug for solid NRR 23 protection, or touch on the edge to open the toggle valve, letting you enjoy lighter NRR 7 hearing protection. With the valve open, the built-in acoustic filter lets you hear virtually everything around you, providing excellent situational awareness. Then, when a loud noise strikes the acoustic filter, the earplugs instantly and automatically increase in acoustic resistance, providing you with the defense you need against dangerously loud sounds. This responsive noise blocking is perfect for blast noise and other loud intermittent sounds, including impulse noise from small arms fire, arc flash from a welding rig, jackhammers on a construction site, or even the noise of a table saw or nail gun. As you can see, Combat Arms Gen 4 ear plugs, made specifically to meet the demanding challenges faced by military operatives, have a very broad range of applications across the civilian, police, and military operations spectrum. Sizes, Replacement Tips, and Packaging Combat Arms Gen 4 ear plugs come with a triple-flange replaceable tip. Our Got Ears? Premium Triple Flange Replacement Tips are a direct replacement for the regular size Combat Arms Gen 4 ear plugs (though they may be beige instead of tan).
