The new ER•20XS is the highly-awaited next generation of Etymotic's industry-leading ETY•Plugs® High-Fidelity Earplugs. ER•20XS eartips are interchangeable. ER•20XS earplugs can also be used with foam eartips with essentially no change in response.
ER•20XS earplugs are discreet and have the identical response of ETY•Plugs through 4 kHz. Above 4 kHz they have improved high-frequency clarity without compromising protection.
ER•20XS earplugs feature a low-profile, stem-less design that sits snugly in the outer ear without protruding. This makes it especially comfortable to wear under hats, helmets and other headgear. ER•20XS earplugs come with a small, flexible pull tab that allows for easy removal, an easy-to-install neck cord and a carrying case.
ER•20XS 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 provide almost equal sound reduction (20 dB) across the range of hearing. Foam earplugs reduce the high frequencies, resulting in muffled speech and music.
