Product Overview

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.

Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Great value with a clear and flat enough response If you want to actually hear what music sounds like, foam plugs are not an option. These earplugs are cheap yet have a flat enough response to still enjoy music. Obviously they're not going to block out massive subs playing under 50Hz, but since that's picked up by your body as much as your ears I don't think any earplugs would. I would recommend these to anyone wanting protection at concerts or musicians looking to protect their hearing. 19 February 2014
