The yellow end of the Combat Arms Military Ear Plug features a precisely engineered chamber with no moving parts. This chamber allows voice level sound to pass through with very little attenuation allowing you to clearly hear voices without removing the earplugs, but severely restricts louder noises, protecting you instantly and continuously in variable noise and continuous noise environments alike. The variable attenuation of the yellow end makes the Combat Arms earplugs ideal for most outdoor hunting, shooting and construction environments.
The other end of the Combat Arms earplug is a passive, continuous protection plug with a 22 NRR which is recommended for constant noise environments such as commonly found in military transport, in construction equipment operating cabs, and many industrial settings.
Combat Arms earplugs are durable and washable and will last for months even with daily wear. One size fits most people.
Combat Arms earplugs come individually packaged with a hard-shell carrying case.
