Etymotic ER20XS High-Fidelity Universal Fit Earplugs

Etymotic ER20XS High-Fidelity Universal Fit Earplugs


ETY • Plugs® are the world’s highest fidelity non-custom earplugs. They reduce most noise to safe levels while preserving the clarity of speech and the richness of music. ETY • Plugs are configured to replicate the natural response of the ear canal so that when sound enters the earplug, it is reproduced unchanged, exactly the same as the ear would hear it, only quieter.

ER•20XS earplugs come with three interchangeable pairs of eartips for more fitting options. Foam eartips on ER•20XS Universal Fit earplugs work in conjunction with the advanced technology in the earplug itself, offering protection and clear communication.

ER•20XS 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.
