Why SensGard Is Different

Traditional earplugs and earmuffs block or muffle sound. SensGard, using the ZEM® technology, reduces harmful noise while keeping speech and important sounds clear. This makes SensGard ideal for musicians, shooters, DIYers, and professionals who need protection and awareness.
