High-Fidelity ETY•Plugs, Etymotic

ETYPlugs are the world's highest fidelity non-custom earplugs. They reduce most noise to safe levels while preserving the clarity of speech and the richness of music. ETYPlugs are configured to replicate the natural response of the ear canal so that when sound enters the earplug, it is reproduced unchanged, exactly the same as the ear would hear it, only quieter.
