Hearing loss from loud sound affects millions of people, but noise-induced hearing loss is preventable! ER20XS high-fidelity earplugs reduce sound levels while preserving sound quality and clarity. ER20XS earplugs are configured to replicate the natural response of the ear, so sound quality is the same as the original, only quieter. Music, voices and other sounds are clear--not muffled--making ER20XS ideal for concerts, clubs, theaters, aircraft, construction, yard work, airshows, parades, and athletic or motorsports events. The new low-profile, stem-less design fits snugly in the outer ear without protruding, making ER20XS comfortable to wear under hats, helmets, and other headgear. The standard-size eartips fit the majority of ears. ER20XS earplugs are reusable, but with repeated use, the eartips may lose elasticity. For best performance and retention, if you use your ER20XS earplugs frequently, replace the eartips every 3-6 months. ER20XS are not recommended for use with impulse noises such as gunfire, or for sleeping.

Noise induced hearing loss is cumulative and irreversible--and completely preventable! We are constantly bombarded by unsafe noise levels in our daily lives. Regular use of ER20XS earplugs helps protect you from the lifelong effects of overexposure to loud sounds.
Advanced technology lowers sound levels evenly by 20 decibels. Discreet, stemless design fits snugly in the outer ear allowing them to be worn with helmets, hats, and other head gear.
Standard foam earplugs reduce sound more in the mid and high frequencies producing an unnatural, muffled sound. ER20XS earplugs reduce sound evenly across frequencies. Music and speech are clear, only quieter, resulting in an optimal listening experience.
Earplugs must be inserted correctly for optimal effectiveness. Insert the plug by grasping the end cap and inserting until the largest flange is sealed in the ear canal. To ease insertion, pull outward and upward on the ear. Moistening eases insertion of 3 flange eartips. Roll down or compress foam before inserting then hold in place for 5 seconds while the foam expands.
ER20XS are reusable but with repeated use the eartips may lose elasticity. For best performance, if you use your ER20XS constantly, consider replacing the eartips every 3-6 months.
Standard fit 3 flange is the best fit for 80% of the population. Large fit is best for 15%.
Clean after each use by wiping with a damp cloth. Do not immerse the earplugs in water. Do not clean with harsh chemicals. Alcohol is not recommended.
