Product Description
Etymotic Research® ER-25 Single Filter for Musicians' Earplugs™ (Red)
- Fits: Westone’s DefendEar Concert (ES49)
Designed for use with the Westone's DefendEar Concert (Style 49) Musicians' Earplugs. Etymotic filters feature a flat frequency response that allows musicians to hear their performance accurately while providing hearing protection. Etymotic ER-25 Filters provide 25 dB of essentially flat sound reduction from 125 Hz through 8 kHz. Westone recommends the ER-25 filter for situations where the ER-15 does not provide enough hearing protection.
