Disposable and slow-recovery foam earplugs that provide comfortable hearing protection. The Arusha plugs protect against loud or permanent noises by reducing the volume to safe levels, even in heavy-duty noise environments. Simply roll the plug into a small cylinder, insert it into the ear and wait for it to expand comfortably in the ear canal. These earplugs are permanently connected by a plastic cord, so they can be worn around the neck when not in use.
