ER20 Generic Fit Hearing Protectors

ER20 Generic Fit Hearing ProtectorsThe ACS ER20 hearing protector has been allowing musicians and music lovers the world over to enjoy live music without the risk of damage to their hearing. The ER20 is filtered to allow you to enjoy the full dynamic range of your music at lower, safer volumes avoiding the muffling effect that you experience with foam earplugs.

Your audio gatekeeper

The ER20 is fitted with a flanged rubber tip that creates an isolating seal in your ear canal to block out sound so that it can then control what gets in and what doesn't. The central chamber of the plug creates an accoustic channel that feeds the sound up to the filter at the base of the eartip where the ER filter shaves an average of 16dB off across all frequencies giving the effect of turning the volume down on the world around you with no muffling.

The graph below shows the attenuation characteristics of the ER20 against a standard foam earplug illustrating the additional fidelity acheived as the frequency increases.

ER20 earplugs are supplied with their own carry case so you can carry them with you whenever you need them.

MSRP $13.99
