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.
