Etymotic ER20 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. The triple flange design on these musician ear plugs produces a good seal in most ear canals, yielding accurate performance and a comfortable fit for nearly everyone. Sounds are clear not muffled.
ER20 High Fidelity Earplugs reduce the volume by about 20 db--just enough to prevent damage to your hearing, but not so much that you lose the enjoyment of the music. The ER20 has an NRR of 12 rather than 20 because the frequency weighting used in the NRR calculation assumes blocking of higher frequencies more than of lower frequencies, and these plugs do not do that. They are designed to let you hear the full range of music, without distortion across the frequencies.
ER20 plugs are durable, washable, and long lasting. With proper care they will last for months even with daily use. Sold with sturdy carrying cases in quantities of one or more. All packs include a carrying case with each pair of plugs.
