Technical specifications of the ER-20XS earplugs

ER 20XS earplugs 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.

ER-20XS Noise Reduction Chart

Standard foam earplugs reduce sound more in the mid and high frequencies, producing an unnatural, muffled sound. ER20XS earplugs reduce sound evenly across frequencies. Speech and environmental sounds are clear, only quieter, allowing for communication and awareness of your surroundings.
