Unfortunately, wasted money... either you hear nothing or you hear a deafening screech.
Although I read the comments before ordering, I also read the instructions after receiving it, and it didn't work.

The headset has two operating modes, normal and the other one which is noise reduction. In the noise reduction mode, it tends to pick up background noise when the volume is set at 3 or higher. In the normal mode, I haven't been able to use it because it constantly picks up noise. For its price, it is a very decent product. I might even consider getting a second one. Compared to another product I had bought that was much more expensive, I can say that this one is better.

For the money, it's very good I can say. Just be careful not to have it too loud because it distorts, but it really does its job and more at a very good price. Something like this costs over 1000 euros and I am happy that I was able to provide something similar to my loved one with little money and help them.

Good for its price. Good sound, it just sometimes gets feedback. The battery lasts, I think, for a day. Time will tell its durability.

I got it for my mother, she is satisfied for the reason she wanted it but it is sensitive to charging. We will probably get another one to see if the charging issue is our fault or manufacturing.

I bought the product for my grandfather, he has been satisfied so far. It doesn't have any difference from the previous product, which was much more expensive. I highly recommend it.

If you want it for gaming and you want to throw away 20-40 euros, go ahead and get it.
It was purchased as a trial for an elderly person and after 30 seconds of testing, it ended up in the trash. It doesn't fit well in the ear, and if it moves even slightly while in use, it can produce loud high-frequency sounds that are unbearable.
It's better to spend a little more and get something good from a hearing aid store
