ETY-Plugs (TM) earplugs use patented technology (tuned resonator and acoustic resistor) that replicates the natural response of the ear canal so that sound heard with these earplugs is as clear as the original, just quieter. ETY-Plugs earplugs have nearly the same fidelity as Etymotic's Musicians Earplugs (TM) (custom earplugs worn by professional musicians) and are a low cost alternative. Hearing loss is a function of exposure time, the average sound level, and the peak level of very loud sounds. Exposure to excessive noise can cause permanent hearing loss depending on the intensity and duration of the sound. Some persons are more susceptible to hearing loss from high-level sound than others. Protect your ears. In high-noise environments, wear Ety-Plugs. Includes one pair of Ety-Plugs, carrying case, black neck cord and instructions.

About Noise Reduction Rating (NRR)

The EPA requires manufacturers to print a noise reduction rating (NRR) on all non-custom earplugs. The NRR for ER20s is 12 dB, but actual clinical measurements of properly inserted ER20s indicate that these earplugs provide almost equal sound reduction (20 dB) at all frequencies in real ears. The required formula used to determine NRR includes an adjustment for individual variability and for those persons who do not wear ear protection as instructed. Many investigators have found no consistent rank order correlation between the real-world NRRs and labeled NRRs. NRR is computed from laboratory data that are not representative of the values attained in the real world by actual users.

A decent pair of ear plugs
Good product and great value for money. Brings the volume down a notch and I am still able to appreciate the music. Fairly discreet too. Will purchase from you guys again in future.

Value for money
Purchased the same pair from Treoo one year back. The earplugs have served me well and fits in nicely while doing its job of lowering overall sound. The clear color makes it less visible when on stage as well. recommended for musicians.
