5 Steps to Define the Quality of PU Foam Earplugs

(1)Look It: color of the superior is uniform, the inferior is mottled for used material

(2)Touch It: the superior is soft, the inferior is sticky. The inferior will hurt the skin of ear canal

(3)Smell It: the superior is odorless, the inferior smell bad

(4)Pinch it: the more time it takes to rebound, the higher quality it is. It takes 10-60s for the superior to rebound

(5)Cut it: there’re small holes in the plug interior. The smaller, the better quality
