Etymotic Research ER20 High-Fidelity Earplugs

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 use a proprietary tuned resonator and acoustic resistor to replicate the natural response of the ear canal. Sound is reproduced unchanged, as the ear would hear it, only quieter. Standard foam earplugs reduce mid-range and high frequencies resulting in muffled speech and music. ETY-Plugs reduce sound levels evenly, preserving clarity of speech and communication, and richness of music. ETY-Plugs are available in 2 sizes, standard and large. Each yield approximately 20dB sound reduction when worn properly.
