These earplugs feature a reusable, low-profile, stemless design that sits snugly in the outer ear without protruding. This makes it discreet and comfortable to wear under hats, helmets, and other headgear. They come with a small, flexible pull tab that allows for easy removal, an easy-to-install neck cord, and a carrying case. Performance matches Etymotic's original high-fidelity Etyplugs developed for musicians with identical response through 4 kHz and an improved high-frequency clarity above 4 kHz without compromising protection. The richness of music is preserved; speech remains clear, just quieter - with 20 dB equal sound reduction across the spectrum of hearing.
