Etymotic's ETY Concert Earplugs are the world’s highest fidelity non-custom earplugs. Reducing noise to safe levels while preserving the clarity of speech and richness of music. Etymotic ETY Plugs 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.
Studies by Etymotic Research and an independent lab show that the ETY Plugs® standard size fits the majority of ears. Ear size cannot be predicted by the appearance of the outer ear, or by a person's physical size, age or gender.
