Etymotic Research ER20 High-Fidelity Earplugs, Blue Tip with Clear Stem, 1 Pair Standard Fit

Hearing loss from loud sound affects millions of people, but noise-induced hearing loss is preventable! ETY-Plugs are the world?s first ready-fit, high-fidelity earplugs that reduce sound levels evenly while preserving sound quality and clarity. ETY Plugs replicate the natural response of the ear, so sound quality is the same as the original, only quieter. Music and voices are clear–not muffled–making ETY Plugs ideal for concerts, clubs, theaters, aircraft, construction, yard work, airshows, parades, and athletic or motorsports events. The standard size fits the majority of ears. ETY Plugs are reusable, but with repeated use, the eartips may lose elasticity. For best performance and retention, if you use your ETY Plugs frequently, replace them every 3-6 months. ETY-Plugs are not recommended for use with impulse noises such as gunfire, or for sleeping or swimming.
