【Professional Passive Noise Isolation Technology】Effective, consistent acoustic seal for a more immersive listening experience from unique dual-foam design that blocks out sound. The earplugs for sleep are achieved by using acoustic foam pads in the earcups to create a secure seal. Protect your hearing when shooting, woodworking, sporting events, mowing the lawn, or in other noisy environments, such as airports and construction sites.

【Replaceable Ear Pads - Keeps Earplugs Clean】Insert design compared to glue allows for quick and easy replacement of ear pads, just push out the old pads and push in the new ones. Replace the gel earcups on a hot summer day and let your ears breathe deeply.

【Authoritative Certification and Professional R&D】Noise reduction science is more about biology. There are so many shapes and sizes of the human ear to study, measure, and test. We have scanned hundreds in pursuit of better fit and comfort to ensure optimal sound blocking.

【Ergonomic Design】Wide earcups with ultra-thin padded ear pads and the headband with a thick layer of padding help them fit snugly around the ears without pressure. And even more importantly, made with an adjustable headband, the headband stretches, contracts, and bends to fit all head sizes and shapes.
