Solid filters for maximum attenuation in ER Series Musician Earplugs molds.
Etymotic sealed-diaphragm solid filters provide approximately 30 dB attenuation (5 dB more than the ER-25), based on measures performed at E-A-R Cal Laboratories, Indianapolis, IN, using the ANSI standard Real Ear Attenuation at Threshold (REAT) method. Thus, the ER Solid Filter fits in the same space as the filters in Musicians Earplugs, providing greater attenuation but less fidelity than a Musicians Earplug.
Only available in clear.
