Etymotic Research ER20XS Universal Fit High-Fidelity Earplugs, Clamshell Packaging

ER20XS Universal Fit High-Fidelity Earplugs feature a stemless 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 headgears. A small, flexible pull tab allows for easy removal. ER20XS Universal Fit earplugs come with 1 pair of earplugs and 3 pairs of interchangeable eartips for more fitting options. Foam eartips on ER20XS earplugs work in conjunction with the advanced technology in the earplug itself, offering protection and clear communication.
