Technical specifications of the ER20xs Earplugs

ER-20XS plugs use a tuned resonator and acoustic resistor to replicate the natural response of the ear canal. This unique construction, combined with Etymotic’s proprietary sound path, reduces sound levels evenly across the frequency range without changing the sound quality. Result: Music and speech remain clear, but quieter and safer.

ER20XS earplugs provide almost equal sound reduction (20 dB) across the range of hearing. NSR (noise reduction rating) of 13 dB.

    I tested these earplugs at a concert and thought they were great. They fit well, and the concert still sounded great, just taking the edge off the volume. With the cord to attach them to and small carry case, I wasn’t worried about losing them, either. Very happy. Cheers, Michael B.

    Worked really well at a concert! They made music sound quieter without muffling or distortion, highly recommend.

    Lost my last pair of earplugs so decided to go with etymotic for my replacement. Good seal and doesn’t affect the quality of sound.
