Etymotic ER 20 Ear Plug #1030

Unlike foam based earplugs, the Etymotic ER20’s cut about 12dB, but leave your ability to hear radar detector chirps, gas station conversations, emergency sirens, etc...unhindered. They are sophisticated noise attenuators that use a patented internal acoustic dampening network to provide nearly uniform attenuation. The washable ready-fit eartips are very comfortable and the end cap is easy to grasp. Advanced technology hearing protection.
