Overall small size and protruding from the ear hole to the outside is small, it does not feel discomfort even if turning over. There is also a quiet feeling.

Noise countermeasure when using the laser microscope room

I used one that cost more than 100 yen per pair, but the fit is far better than that. I tried to compare the size of the ear with the small hole, but the same. Cost performance is the best among those used so far. If you buy more at a lower price, you buy a lot.

When working with a microscope

The room of the laser microscope is so noisy that I am trying various ear plugs, but this is wonderful! ! Anyway, it fits in a kanji like to be packed in the ear, and the sound insulation is also wonderful, it is even more pleasing if it can be bought at a discount for a number of items collectively.

Even though it is cheap, it is a high-performance, reliable brand. Cospa is the strongest.

Used for noise control of the subway

I can hear the high-frequency sound well and I can not tolerate compressed air discharge noise of the train, so I always do earplugs when I get on the subway. This was the best sound insulation we had ever had.

Usual for sleeping

It is soft and light, has a better fit and sound insulation than any ear plugs used up to now, and the ear will not hurt even when used for a long time. I can not use other earplugs with surprise and impression after using once! The difficulty is soft and easy to push in so far, so sometimes it is difficult to take out a little but if you do not want to be greedy it will not be a problem.

Sound insulation, outstanding durability. Even if I use it like everyday the sponge does not collapse at all. Truly 3M.

Although I used 100 hundred things up to now, this one is small and soft and the sound blocking is also good.
