The 3M™ E-A-R Soft™ Metal Detectable Corded Earplugs, feature a stainless steel ball bearing in the earplug and metal particles in the cord to aid in locating the earplug if lost. Metal-detectable foam earplugs were developed for food processing and other industries where it is critical to keep earplugs from contaminating products and processes. The bell-shaped earplugs seal the ear canal with soft, slow-recovery foam for excellent noise reduction.
