Used when airing.

Because the air sound is large, there was a limit in the earplug, but after using this type it is gentle to the ears, even the earmuffs got hammered, people's voice is heard, and internal environmental measures became.

It fits to the ears and the machine sound is considerably reduced, so it is good, but I feel that tightening is too tight.

I feel easy to use if the spring is a bit more soft, but the sound insulation effect was enough for me personally. Since the spring is annoying around the neck, I use it upside down.

Once opened from the bottom, it was one that was closed with tape. Even if it is unused it is not a good feeling. Do I get such things with coupons?
Measures against noise work

It is a really light earmuff. When clothes collar etc hit the metal fittings passing behind the neck, I hear the sound of crunchy echoes in the earmuffs. I got used to it, but it is regrettable only there. When I use it, I try to wear clothes that are not collared as much as possible. Because it is NRR21, it responds well enough to a fairly noisy place. In a very noisy place, I feel a little uneasy but I think that I'm fulfilling the work of figures.

I can not hear anything with the spiral earplug and this ear muff, and I am saved.

With earplugs, we decided to use earmuffs because of the shortage. This type can be attached even when you wear a helmet. The helmet mounting type purchased this type because the helmet becomes heavy.

How to use it has an earpiece from the top of the hat (hood) for welding. In order to suffer a helmet, I like to cut things like strings at the top of the head. I am very satisfied with all aspects. I will buy the same thing as soon as it collapses or loses it. Thank you for offering good goods.
Mechanical sound in factory speech

When used in conjunction with earplugs, I feel that the sound insulation effect is higher. It seems easier to use than a headphone type.
