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•Plugs™ 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.
