ER 20 High Fidelity Hearing Protection
Ready-Fit Earplugs ER 20 with Case ETY Plugs (ER 20 High Fidelity Earplugs) were developed to provide low-cost, one-size-fits-most high fidelity earplugs that can be used in a variety of noisy environments.
The goal of the ETY Plug design was the same as for Musicians Earplugs: to reduce noise but preserve sound quality; in effect, to turn down the noise but not muffle voices, environmental sounds or music.
ETY Plugs use a patented tuned resonator and acoustic resistor that replicate the natural response of the open ear so that sound heard with these earplugs is as clear as the original, just quieter.
* Replicates the ear's natural response
* Speech is clear, not muffled
* Reduces approximately 20 dB at all frequencies
* Sound quality is preserved
System Includes * High Fidelity Earplugs * Carrying Case * Instructions
If you do not specify which color you would like, I will choose one at random.
