Hearing loss from exposure to loud sound affects millions of people. Noise-induced hearing loss is preventable. And it"s easy to prevent. ETY-Plugs were developed to provide low cost, one-size-fits-most high fidelity earplugs that can be used in a variety of noisy environments. The goal of the ETY-Plugs design was the same as Etymotic"s famous Musicans Earplugs: to reduce noise but preserve sound quality; in effect, to turn down the noise but not muffle voices, environmental sounds, or music. These high-fidelity earplugs are effective or anyone who needs to hear accurately in noise: attendees at concerts, clubs, other loud performance venues; aircraft personnel; construction workers; industrial workers; medical/dental workers; workers in environments with loud music such as concert halls, nightclubs or bars; emergency vehicle personnel; athletes; participants in motor sports; truck drivers. Each purchase includes high fidelity earplugs, black cord, carrying case, and instructions. Easy to carry in your purse, backpack or pocket. Available in standard size for smaller ear canals or large size for larger ear canals.
