Dubs Acoustic Filters are advanced tech earplugs acoustically engineered to reduce the volume while preserving the clarity of sound at music venues and in other loud environments. Developed as a solution to the growing problem of noise-induced hearing loss in young adults, they redefine how the earplug should look, feel and sound. The special design sits flush within the ear and masks the complexity of the Dubs proprietary audio filters. The product is durable, reusable and comes with a convenient carrying case.
