The highly-anticipated next generation of Etymotic Research's industry-leading ETY•Plugs High-Fidelity Earplugs, the ER•20XS earplugs now accomodate interchangeable eartips, with this particular set [ER20XS-UF-C] offering a universal fit (UF) package, including 3 Eartip pairs: Standard, Large, and Foam. Even used with foam eartips, they retain essentially unaltered, uncolored response. Additional eartips are available, although they're sold separately. They're discreet and provide the identical response as the ETY•Plugs through 4 kHz, but higher than 4 kHz they deliver improved high-frequency clarity with no compromise in protection. They feature a low-profile, stem-less design that snugly sits in the outer ear with no protrusion, making it especially comfortable for wearing under hats, helmets, and other headgear. This set of ER•20XS earplugs – along with the included eartips, feature a small, flexible pull tab that enables easy removal, as well as an easy-to-use neck cord, plus a convenient carry/storage pouch, all packaged in a "clamshell" retail container.
