The ERs are the original high-fidelity, custom moulded, flat response earplugs giving 25, 15 or 9db of clear hearing protection. Designed to match the ears natural response, so speech and music can be heard clearly, with the original quality, only quieter. ER custom earplugs shelter music professionals from the risk of damaged hearing.
Accurate sound reduction is achieved by combining a patented filter with the specific acoustics of a custom earmould. The combination produces a smooth, flat attenuation. Speech and music are clear – you still hear the mix clearly, feel the bass, and distinguish each tone.
