Etymotic ER20XS High Fidelity Earplugs are the highly-awaited next generation of Etymotic's industry-leading ETYPlugs® High-Fidelity Earplugs for musicians. Etymotic ER20XS High Fidelity Earplugs feature patented Hi-Fi technology that lets you hear all frequencies clearly, just as if you had no plugs in, but at a lower volume level.
ER20XS earplugs feature a low-profile, stem-less design that sits snugly in the outer ear without protruding. This makes it especially comfortable to wear under hats, helmets and other headgear.
ER20XS earplugs come with a small, flexible pull tab that allows for easy removal, an easy-to-install neck cord and a carrying case.
ER20XS earplugs are discreet and have the identical response of ETYPlugs through 4 kHz. Above 4 kHz they have improved high-frequency clarity without compromising protection.
ER20XS eartips are interchangeable. ER20XS earplugs can also be used with foam eartips with essentially no change in response.
NRR 13
An NRR of 13 means that the hearing protection is estimated to reduce noise levels by an average of 13 decibels across various frequencies.
'NRR' in hearing protection stands for 'Noise Reduction Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the NRR value, the greater the noise reduction level is considered to be.
NRR is primarily used as a rating system in North America, while Europe often uses 'SNR' (Single Number Rating) and Australia/New Zealand use 'SLC80'; which both differ slightly in calculation.
SNR 17
An SNR of 17 means that the hearing protection is estimated to reduce noise levels by an average of 17 decibels across various frequencies.
'SNR' in hearing protection stands for 'Single Number Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the SNR value, the greater the noise reduction level is considered to be.
