Etymotic Research Etymotic High-Fidelity Earplugs ER20XS Universal Fit Hearing Protection

Description

Loud hearing loss affects millions of people, but prevents noise inducing hearing loss. ER20XS Hi-Fi ear plugs reduce sound levels while maintaining sound quality and clarity. ER20XS earplugs are constructed to replicate the natural response of your ears, so the sound quality is just as quiet as the original. Music, voice and other sounds are clear -- no blurred--ER20XS is perfect for concerts, clubs, theaters, aircrafts, construction, garden work, air shows, parades, athletic and motorsport events. Low profile stemless design fits snugly in the outer ear without protrusion, ER20XS is comfortable to wear under hats, helmets, and other headgear. Standard size ear tips fit most ears. ER20XS earplugs are reusable but will lose their elasticity after repeated use. For best performance and retention, if you frequently use ER20XS earplugs, replace your ear tips every 3-6 months. ER20XS is not recommended for use with impulse noise such as firefire or sleep.
