Etymotic ER20 Ear Plugs

Unlike foam based earplugs, the Etymotic ER20’s cut about 20dB at all frequencies, but leave your ability to hear radar detector chirps, gas station conversations, emergency sirens, speech, 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. Reusable, but with frequent repeated use, replace every 3-6 months for best performance. Two sizes available – Standard and Large.
