Worker's speech inside the factory · For machine noise

I think that it is easier to insert and remove it than the type without core and it is also excellent for blocking sound. After a while, you can not hear people's talking much.
When using a chain saw, a grass cutter

It is easier to use than a type that crushes and pushes it. It is hard to hurt even in my ears. If you put it firmly, noise can be reduced considerably. NRR 30 is not set.
