The interlocutor doesn't hear you very well unless you bring the headset close to your mouth, but for their price, they are fine.

While at first the sound was satisfactorily loud, after 3 months of continuous use, the sound started gradually decreasing and now I can hardly hear anything

Very nice sound but they only lasted for a week, without any mistreatment, as I leave them spread out on the desk and they haven't been pulled or hit. I wouldn't buy them again.

Very good headphones for their cost. They are comfortable and the sound is so natural that it doesn't tire you at all to listen for a long time... Definitely value for money.

They are headphones that do not break... I have had them for 7 months... I used to change headphones every 15-20 days because I use them a lot... I even sleep with headphones, no exaggeration...
They are worth it in terms of material quality, the only thing they lack is that their bass is a bit low...
They are worth their money, I would buy them again

They were purchased for a person who is a bit careless with this category of products. However, these particular ones manage to hold up even after 4 months of continuous and extremely intense use (even during the summer months with sea and sand). I highly recommend them and I will definitely choose them again in the future.
