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.

When taking a break at work, for a nap

It fits tightly and interrupts the sound. Although it is a repeat, it lasts longer than other similar sponge types.

Sleep, used when sleeping

Because the rebound is somewhat strong, it can be made small by crushing strongly (じ じ る), but if you do not put it in your ear quickly it will inflate before you insert it all the way back. However, it is possible to use it without trouble if it matches timing and even timing. Since the material is soft, it does not feel stress at all even if it is in the ear, so it will not feel stress or feel pain even after long-term use. The durability is more than the price of goods. (The durability is high for 100%)

A nap at lunch break

Sound insulation, fit is good, but it is brittle. I tore it when I took it, and experienced twice when I was having trouble getting it. Of course, ripped goods can not be reused. Because other earplugs do not tear like that, I think that this product is not good.
