ER20 High Fidelity Earplugs feature a traditional stem and triple flange design for a superior seal, offering unmatched noise reduction without sacrificing sound clarity. Perfect for environments where preserving speech and music quality is essential, ER20 earplugs ensure sounds remain clear and rich, just at safer volume levels.
Immerse yourself in unparalleled sound clarity with ER20 High Fidelity Earplugs. Designed with a traditional stem and triple flange tips, these earplugs create an exceptional seal in the ear canal with three points of contact. This design ensures maximum noise reduction and superior sound fidelity compared to single dome silicone tips.
The ER20 earplugs use a proprietary tuned resonator and acoustic resistor to replicate the natural response of the ear canal. This technology allows sounds to be reproduced unchanged, just quieter, ensuring that most noise is reduced to safe levels while preserving the clarity and richness of speech and music.
Unlike traditional foam earplugs, which can muffle sound and reduce mid-range and high frequencies, the ER20 earplugs evenly reduce noise levels. This preserves the clarity of speech, communication, and music, making them ideal for various settings where maintaining sound quality is essential.
BENEFITS
CHOOSING YOUR SIZE
All ears are different. It is impossible to predict the size of an ear canal by the appearance of the outer ear, or by a person’s physical size, age or gender. Two sizes of ER20 Plugs fit almost 100% of ear canals. Recent studies of both fit and seal, conducted at Etymotic Research and an independent lab, showed that the smaller of the two sizes fits the majority of ears and is now designated as standard fit.
ADJUSTING TO ETYMOTIC EARPLUGS
A little time may be required to acclimate to these earplugs. Many musicians report that they hear their own instruments better, as well as the balance with those around them.
Insert the plug by grasping the end cap and inserting the eartip until the largest flange is sealed in the ear canal entrance. To ease insertion, moisten the plug and pull the ear outward and upward. Earplugs must be inserted correctly for optimal effectiveness. To remove, use a slow twisting motion.
WHEN TO REPLACE
ER20 Plugs are reusable, but with repeated use, the eartips may lose elasticity. For best performance and retention, if you use your constantly, replace them every 3-6 months.
Understanding Noise Reduction Ratings for Etymotic ER20 Earplugs
We know that protecting your hearing is crucial, and we want to ensure you have all the information you need about our Etymotic ER20 earplugs. You might notice a difference between our claim of a 20dB noise reduction and the Noise Reduction Rating (NRR) listed on the packaging. Let’s clarify this for you.
What is NRR? The Noise Reduction Rating (NRR) is a standardized measure that indicates the minimum level of noise reduction you can expect from a hearing protection device in a “worst-case” scenario. It’s designed to give users a baseline expectation of the least amount of attenuation (protection) they might receive.
Why the Discrepancy? While the NRR provides a conservative estimate, extensive testing and real-world data show that the typical amount of noise reduction achieved with our ER20 earplugs is around 20dB. This higher level of attenuation reflects the performance most users will experience in everyday use.
Transparency Matters We understand this discrepancy can be confusing, so we want to be transparent. You’ll find the official NRR rating on our packaging and user manuals. Our goal is to provide you with accurate information to make informed decisions about your hearing protection.
