When using a grinder

Although there is no problem with sound insulation, worry because the eardrum is pressed when desorbing. Also, a tremendous sound is heard when clasping protrusions to use for desorption are caught in towels etc .... Next time I would like to try out products without sponge-like projections.

I will spend swimming in the pool.

Materials are also soft and fit well at a value price. It is easy to take out and I am satisfied with good goods.

The soundproofing effect is moderate (others have soundproofing ears). I think that it is good to have a waterproof effect without being attached once attached.
When I want to be quiet

It is set in one shot. Moreover, the noise shuts out. This is recommended.
For ensuring sleep

I liked this much only because I tried a variety of earplugs but I could use it without falling off.

Previously I used sponge type things, but I had to crush with a dirty finger, the ear was dirty and there was no help for it. This product has a handle and it is very good because it can be handled with dirty hands. You can handle it while you are wearing gloves. Soundproof performance is also a point.
