I bought various types of relatively early ears on a monotail and actually tried it, but this product had the most effective soundproofing effect. It is easy to wear because it is easy to wear, so it fits quickly to the ear hole, but it seems to be a little long compared to the length of the ear hole, so it feels slightly jumped out, but it does not get it. I can carry it because it has a case so I think it will be useful when I want to concentrate on simple tasks or conversely head-using work.
It is used during machine work. The sound deadening effect is also very good fitting to the ear. Because it is 40 pieces, you can use for the time being. The price is also cheap and it is very helpful.
