For the noise of the work for the people speaking and machinery in the factory

Core is easy to insert or remove than not type, I think that is also excellent in the blocking of the sound.
After a while you put, also I do not hear too much speaking of people.
Chain saws, when using the mower

It is by far the easy-to-use than the type to push crush.
It is hard to be hurt in the ear.
If you put firmly, noise can be considerably reduced.
NRR30 is not a Date.
