Replacement Etymotic Filters for Musicians’ Earplugs.
Designed for use with the Westone ES49 Musicians’ Earplugs.
Etymotic filters feature a flat frequency response that allows musicians to hear their performance accurately while providing hearing protection.
The ER-15 provides a uniform flat 15 dB of sound reduction from 125 Hz through 8 kHz. The most popular of the Etymotic Research flat response attenuators, the ER-15 is recommended as the first choice for hearing protection for musicians, whether they perform in the symphony or local rock band or they teach music at school.
