The ER-20 ETY-Plugs Triple-Flange Earplugs (Standard, Clear/Blue) from Etymotic are a compact and inexpensive way to reduce sound levels around you, while still maintaining the ability to hear clearly. Ideal for use by musicians and those who work in loud environments such as parades, motor sports, and athletic events, these high-fidelity earplugs reduce sound by up to 20dB across all frequencies.
By reducing sound evenly, the earplugs reduce the risk of hearing damage, but also keep music and speech clear and natural, not muffled. The earplugs are configured to replicate the natural response of the ear canal so that sound comes through exactly as it should, only quieter.
