ER-20XS earplugs come with three interchangeable pairs of ear tips (standard 3-flange, large 3- flange and foam) for more fitting options. Foam ear tips on ER20XS Universal Fit earplugs work with the advanced technology in the earplug itself, offering protection and clear communication.
ER-20XS Universal Fit Ear Plugs 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.
The ER20XS is the next generation high fidelity Etyplug, reengineered to fit in an eXtra small compact form factor.

Technical specifications of the ER-20XS earplugs
ER 20XS earplugs 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. NSR (noise reduction rating) of 13 dB. Standard foam earplugs reduce sound more in the mid and high frequencies, producing an unnatural, muffled sound. ER20XS earplugs reduce sound evenly across frequencies. Speech and environmental sounds are clear, only quieter, allowing for communication and awareness of your surroundings.
