To purchase a variety of relatively high rating earplugs in Monotarou, but was actually tried, This product has had the effect of the most soundproof. So easy to tapering the mounting if easy, but it fits into the ear hole puffy immediately, Because compared to the length of the ear hole I feel a little long so, although there is a feeling that a little pop, But does not navvies. With so cases it can also carry, when you want to concentrate on my work to use the head to the simple task and reverse, I think that helps.
