Etymotic Research ER20XS-SMF-P ER•20®XS Standard Size High-Fidelity Earplugs in Polybag

The eagerly-awaited next generation of Etymotic Research's industry-leading ETY•Plugs® High-Fidelity Earplugs, the ER•20XS earplugs now offer interchangeable eartips. ER•20XS earplugs can also be used with foam eartips, while remaining essentially unchanged in audio response. Additional eartips are available, although they're sold separately. These units are discreet and provide the identical response as the ETY•Plugs through 4 kHz, but higher than 4 kHz they deliver enhamced high-frequency clarity with no compromise in protection. Their low-profile, stem-less design snugly sits in the outer ear with no protrusion, so they're especially comfortable when wearing under hats, helmets, and other headgear. The ER•20XS earplugs provide a small, flexible pull tab that offers easy removal, as well as an easy-to-use neck cord, plus a convenient carry/storage pouch. This particular product comes in a "polybag" retail package.

Etymotic Research ER•20XS Specifications:

• Manufacturer code: ER20XS-SMF-P
• 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. See frequency response comparison chart below:
