They are excellent! They significantly reduce noise in very noisy environments while still allowing you to hear your conversation partners. I also love that their case is a keychain, so I always have them with me.
I have always been a bit sensitive to noise and honestly, I regret not buying them sooner...

They do their job but an old pair of earphones (buds) with the classic silicone construction would do the same. Extremely expensive product at 30 euros

Very good and comfortable earplugs that do their job without muffling everything. I use them both when I go to concerts as a listener and during rehearsals or live shows I do as a guitarist in a metal band. You choose the color of the plug that suits your needs and that's it. Also, the metal case is super practical as it allows you to keep them on your keys, for example, so you never forget them.

I have been using them for a few days and only during sleep, but I can say with certainty that they completely isolate external sounds (annoying neighbors) and offer you quality sleep. It takes a little time for your ears to get used to them, but they really saved me!

I used them at a concert with very loud volume, in an indoor space, and they performed amazingly. On the low protection setting, they let through just what was needed from the music without losing any quality.
After the concert, my ears were perfectly fine, with no ringing or pain.

In general and with proper placement, they offer quite good sound insulation. At least for sleeping, which is what I use them for, they isolate to a large extent annoying sounds that are within a radius of 15 to 20 meters, although they do not achieve this 100%.
I emphasize that they need to be inserted quite deeply and correctly, and when I say correctly: we need to wait 2 to 3 seconds for the plastic rings to return to their original shape inside the ear.
I have not experienced any discomfort or pain in my ears.

After daily use, I can say they are well worth the money and even more!!!
After the experience I gained in placing them, they isolate sounds by more than 90% (so as not to exaggerate by saying 100%).
Absolutely satisfied!!!

DO NOT BUY IT,
You will lose it! The first month I lost the bottom part and the second month the top. It unscrews by itself and at some point it won't even exist...

I bought them for concerts to avoid the ringing that stays in the ears. They work perfectly. They lower the frequencies but you can hear everything clearly, even the person next to you when they speak to you. It has two filters inside so you can change depending on the volume you are in. I would say value for money!

Just what you need for concerts. You leave afterwards and your ear health is as if you never went. It reduces speech a bit but it's manageable. I used the gold ones which have better isolation

Savior from noisy neighbors who wouldn't let me sleep. If you position them just right so they fit perfectly in the ear, you don't hear very loud sounds.

The case for the earphone filters unscrews easily, risking the loss of the filters or even the entire case. In terms of quality and performance, it is excellent!

Very good but unfortunately I didn't get to use them more than once... their case is screw-on, and while walking it unscrewed and got lost somewhere at a festival in Germany...

Discreet in the ear, they offer a better entertainment experience in places with loud sound. You can comfortably talk to people. No more buzzing in the ear.

Very good. As a drummer, they saved my ears. The filter is good, but let's not say just anything; it cuts frequencies (a bit in the highs) but has nothing to do with simple earplugs.

Excellent! I use the silver ones (medium). The gold ones are excessive (you don't hear anything). Thanks to these, I leave the club where I work as security (and where I have to listen as well) without buzzing and headache / babbling (120dB in the place++). I give it a 4 though because they should have a spare rubber band

I can't say that I was satisfied. I bought them because I go to many concerts every year to avoid burdening my hearing. They excessively reduce the volume to a point that annoys you. I tried them with the "weakest" filter at a concert at Release with maximum sound intensity, being 50 meters away from the center of the stage, and the sensation was like having noise-canceling headphones, as they significantly reduce the background noise of the crowd, and I had the song playing from my phone at half volume. They also cut off a lot of the high frequencies. Surprisingly, I could hear quite well when someone was talking to me. I feel that their only usefulness might be in a place with very loud noise where you want to be able to talk to the person next to you. I don't think they are suitable for concerts. After 5-6 songs, I took them off to be able to enjoy the music and the vibe of the crowd.

The two filters cover every need and the case is very practical. We used them at the release festival on the metal days while we were at the front row, facing the speakers, and they did an amazing job! They covered the strong bass and the sound was pretty good. Only two downsides. If you sweat, they tend to slip a bit from the ear, so they require some attention, and also inserting and removing the filters wears out the silicone to the point where I'm afraid it will break.
