ER20 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 ER20 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 musicTo combat the effects of Tinnitus the ER20 earplugs were developed for musicians so they could safely protect their hearing without compromising their performance. Now you can enjoy these benefits too – whether you’re clubbing, dj’ing, or just want to shut out noisy neighbours, ER20’s will help you avoid the irreversible long term effects of hearing loss.
Almost 75% of 18-30 yr olds who regularly go clubbing have temporary tinnitus. As a result of prolonged exposure this can become permanent.
