This earplug’s moisture resistant foam is initially firm to make fitting the earplug easier, softening once it?s in the ear to comfortably expand and conform to the shape of each ear canal. The slow recovery feature helps with earplug insertion by giving the user time to get the compressed foam cylinder (rolled down earplug) into the ear before the foam fully expands. Per-pair packaging options include a pillow pack that can be used to store earplugs between uses or a standard polybag; dispenser bottles for One Touch Pro dispenser are also available. Comes with or without cord to suit user preference. This product is EARfit testable to help validate the level of protection the individual user can achieve with this product.
