The Etymotic ER-20 Ety-Plugs
Protect Your Hearing Without Loss of Clarity
ETY-Plugs are the world's highest fidelity non-custom earplugs. They reduce most noise to safe levels while preserving the clarity of speech and the richness of music. ETY-Plugs are configured to replicate the natural response of the ear canal so that when sound enters the earplug, it is reproduced unchanged, exactly the same as the ear would hear it, only quieter.
ETY-Plugs 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. Foam earplugs reduce the high frequencies, resulting in muffled speech and music, but ETY-Plugs provide almost equal sound reduction (20 dB) across the range of hearing.
