Etymotic ETY Earplugs

The world's highest-fidelity non-custom earplugs reduce most noise to safe levels while preserving the clarity of speech and the richness of music. ETY-Plugs 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. The standard size fits about 85% of people, and a larger size is also available.
