Product Information

New Discreet Design

ER-20XS earplugs are discreet and have the identical response of ETY-Plugs through 4kHz. Above 4kHz, they have improved high-frequency clarity without compromising protection.


  • Performance matches Etymotic's original high-fidelity earplugs developed for musicians
  • Unsurpassed clarity
  • 20dB equal sound reduction across the spectrum of hearing
  • Richness of music is preserved; speech remains clear, just quieter
  • Reusable

ER-20XS earplugs feature a low-profile, stem-less design that sits snugly in the outer ear without protruding. This makes it especially comfortable to wear under hats, helmets, and other headgear. ER-20XS earplugs come with a small, flexible pull tab that allows for easy removal, an easy-to-install neck cord, and a carrying case.
