In company factory

I use it in the factory of the company.
The sound of the machine was noisy, I bought it so that it will not affect my ears
Although the sound is reduced, it is convenient because you can hear the talking voice.
It also fits the ears and is hygienic as it can be washed.

Washing after using it with silicon material, because it can wipe it is convenient to save cleanly.
It did not suit my ear at all

It did not fit at all with quite hard eyes. Sound was not absorbed at all and I was sorry very much. Perhaps it is good for the person who meets it, but it is difficult to not try in advance.

Although sound insulation is not bad, personal taste comes in touch and detachment. Some workers say it is good, but others are not good.
Used when airing.

Each person carries it, it can be used at any time by air work, because it has a handle, it is easy to put in when you put it in your ear, it is soft, so it is gentle to your ears.

When it is used for several months in a row, elasticity performance seems to change, and if it is S size, it has fallen off naturally from the ear. I was conscious from the time of purchase that the cord is not attached, but it can not be collected even if it falls out. (Because it is in the form of a small badminton wing, I often jump and I do not know where I went.) Even though I blown by air, I did not come out because it rotated.) I thought about trying to buy M size, I'll give it a try.

I bought it for the purpose of preventing engine noise, but it was not very effective. It is regrettable though it seems that the dirt is easier to drop than other earplugs.

Although sound insulation is difficult to express, discomfort like coming in my head even if I hit a steel plate with a hammer has been reduced. But I will notice it if I can speak. Since it is not a dry ear, I think that I can keep it clean every material for every use. Because the case is also included, it is convenient for carrying.

I am satisfied to hear the conversation properly. Is the sound insulation quiet a little? There are three Mimi and it is very painful in some places. In that case it is okay to adjust the position.

I have time to put it in, but it does not hurt even if I use it for a long time. It is more dirty than things like a sponge.
