I will tell you.
Initially, when I bought them and without having worn earplugs before, I was not satisfied, probably because I didn't know how to put them on properly. Like others have written, they would fall out during sleep, and I thought they didn't protect against many noises, etc.
After getting used to them, I learned to mold them before putting them in my ear, and then slowly insert the remaining part, resulting in them never coming out during the night and significantly reducing the surrounding noise. To the point where I was worried if I would hear my alarm clock or not! People would talk next to me and I wouldn't hear anything.
In the end, I would definitely buy them again!
I sleep perfectly now.

I have been wearing earplugs for 10 years.. I always buy the cheap ones that cost 0.60 euros.. I thought let me buy the more expensive ones maybe they hold the sound better (I paid 6.5 euros for them) I'll tell you one thing, the first night I wore them outside for a while because they felt a bit hard, I thought let's sleep and see.. my ears were hurting a bit.. the next night I thought let me wear them properly maybe that's why I felt pain... well, I woke up in the morning from the pain! Like an ear infection... I took painkillers.. oh my god what was that thing, I threw them away as they were.. go away!

It's a matter of reducing 10% of the noise. Useless, just like the others I have tried. And yes, I apply them correctly. They really completely block the sound. I really can't understand how they say they can't hear anything when wearing them.

After many trials, I ended up with these earplugs! They are quite comfortable, but as with all earplugs, if you wear them for many consecutive days, your ears will hurt. You can wash them, they lose a bit of their elasticity, but their use is extended for a while

1) They are very comfortable.
2) They fit perfectly (if you know how to place them).
3) They greatly reduce noise to the point that you need to be cautious, as if something happens in the space you are in, there is a possibility that you may not perceive it.

Tremendous insulation if applied correctly, even for impact-generated noises. Unfortunately, they hurt the ear canal too much, to the point where I can't use them after a few days. After the first application, they hurt me terribly, so I wear them quite superficially (they still hurt but at least not as much) and they still do a good job even like that.

They are very good but they need frequent updating. I have also tried another company's 40db and it satisfied me more. I would like this company to also release a 40db. The price is a bit expensive.

Funny somehow to evaluate earplugs, but these are the only ones I have been using for years now, mainly because they are so comfortable that I don't feel them at all in my ear and because I can't hear my doorbell when I wear them! A bit expensive, but I wash them in the washing machine regularly.

Very good, they fit easily, they don't hurt the ears, they greatly reduce noise, they are durable, and they can be washed. I will buy these again!

They are the only earplugs that don't give me a headache. Any other ones I've used put too much pressure on my ears and I couldn't sleep.

In terms of sound, they cover me so that I am not bothered by neighbors dragging furniture every night, not hearing dogs and cats meowing outside, and not being bothered by the guy across the street with his loud exhaust. They cover snoring to some extent. If the person next to you is snoring like an excavator, what can earplugs do for you? I had them brought from abroad until I found them in pharmacies here.

I don't change them. You see, "to each their own."

A failure! I bought them based on their generally good reviews, but I was completely disappointed! They don't reduce the noise at all, they are very thin, meaning they don't expand when you put them in your ear, resulting in them easily falling out and not providing any protection. Extremely poor quality for their price! I have tried better earplugs at a third of the price. The only positive thing is that they are comfortable. I wouldn't buy them again!

Failed purchase, these silicone ones are not good at all.
Small reduction in noise that didn't satisfy me and expensive price.

I have been searching for a long time for earplugs of this type that are easy to apply and minimize environmental noise to the minimum. I tried various brands and well-known ones, but the main problem was that they were not durable and would break after two or three uses. These ones combine everything together. I highly recommend them! You won't find any other earplugs like these.

The only earplugs that don't bother me, because they are very comfortable in the ear. I forget that I'm wearing them. I only buy these for years.

Very good but not cheap, that's why not 5 stars. On Amazon, for example, you can find 20 pairs for the same price in a good brand. The Quies earplugs cut off a lot of dB and almost isolate you from the world. Earplugs of this type need to be molded before insertion into the ear. Otherwise, they won't be effective. Of course, all these earplugs are only for a few uses since it's not healthy to use them multiple times as they cannot be sterilized and at some point, they dry out and get dirty and you have to throw them away. However, this type (foam) has a much better fit and noise reduction than the multiple-use ones.
