ER20s are ideal for many applications with constant high sound levels. Re-Useable ER20 earplugs are configured to replicate the natural response of the ear canal. When sound enters the earplug it is reproduced exactly the same as the ear would hear it, but quieter.
Affordable protection without compromising sound quality.
Virtually 'flat' response across all frequencies.
Re-useable and washable.
Come complete with a laser printed, aluminium carry case.
