Hi, I'm Alison Bailey, I'm a factory owner. I have been running the factory for a long time. But due to the loud noise of the machines in my factory, I have problems with my ears. I consult an ENT doctor to solve my ear problem. He advised me to use some earplugs. I am very grateful that using ear plugs has reduced my hearing problems. If you have this kind of problem, you can also solve the problem by using these earplugs.
