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. Click the Accessories tab below to order additional eartips.
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.
