ER20XS High Fidelity Earplugs Universal – 1 tip option

Description

ER-20XS earplugs come with Standard Clear Stem/Frost ear tip. ER•20XS Universal Fit earplugs work in conjunction with the advanced technology in the earplug itself, offering protection and clear communication.

Etymotic ER20XS Universal Fit Earplugs feature a stem-less design, with a low profile that conforms to the plane of the outer ear. This makes them particularly comfortable to wear under hats and other headgear. A small, flexible pull tab allows for easy removal.

Replacement

Technical specifications

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.
