Studies by Etymotic Research and an independent lab show that the smaller of the two sizes 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

High-Definition Earplugs ETY•Plugs® HD are the world’s highest definition ready-fit earplugs. They reduce most noise to safe levels while preserving the clarity of speech and environmental sounds. ETY•Plugs HD 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. Regular use of high-definition ETY•Plugs HD while operating machinery, power tools or loud vehicles will protect hearing from the cumulative effects of overexposure to loud noise throughout life. A little time may be required to acclimate to these earplugs. Most users comment that they hear speech and environmental sounds better when using ETY•Plugs HD. ETY•Plugs HD are reusable, but with repeated use, the eartips may lose elasticity. For best performance and retention, if you use your ETY•Plugs HD constantly, replace them every 3-6 months.
