I want to use it when I go to bed at night. I think that it is a good product.
Power tool working

Somewhat stiff, but firm. Because it is 3M, it is safe and cheap.

Work noise generated at the site is quite large, but 3M company products are highly soundproof, the noise of the unpleasant grinder is also reduced, and the workers' evaluation is also high, so I have been using it all the time.

Because the restoration time when crushing is long, it is easy to put it in your ear. Sound insulation is also quite different from things sold at Daiso.
Used during sleep.

Even with wearing, there was no sense of oppression, and the soundproofing effect was satisfactory somewhat. I plan to purchase it next time.

Sound insulation when using Thunder
From Japan

The best thing purchased this time is this This is reasonable hardness and the time to return Since the surface is not smooth, it will stay in the same place for a long time Sound insulation is also satisfactory

It's easy to use because it's not too hard and not too soft. It also shuts out the noise firmly.

I can sleep well because it cuts off in a good condition as it is hard to remove and the sound is good.
