Elacin ER's Filtered Noise Plugs
Elacin ER noise plugs feature an individually calibrated filter (9, 15 or 25dB), designed to attenuate all frequencies at the same level. Unlike solid noise plugs which attenuate all frequencies differently, these filtered ear plugs give a flat attenuation across the frequency range. This means Elacin ER noise plugs let you hear sounds accurately, but at a safe and comfortable level for your environment.
Elacin ER noise plugs are ideal for musicians who want to be protected from loud music exposure, but still hear the true sound and frequency range of the music and their instrument. Elacin ER noise plugs are custom-made, and fit deep into the ear canal to give the best comfort and attenuation. Available in clear finish only.
