In general, they do their job, but don't expect anything special. Their price reflects that. If you don't have at least average quality headphones on your head, they will be fine for you. However, their biggest drawback that ultimately makes them useless is that after a few months of use, the cushions come off (slip off) from the headphones. The cushions simply "fold" in the groove in front of the green plastic that is visible in the photos.

I tried many times to put them back in place (a great inconvenience), but they always came off. I glued them with glue for assembly models, but they still came off. When I finally tried with strong glue, they stayed on for several days... until they eventually tore. It's logical since the plastic casing on the cushions is as thin as cigarette paper!

I bought these headphones yesterday and they are quite satisfactory so far. The songs sound great, the audio was good after a two-hour video call with no issues, so it was great. Although I believe that if the sound was louder, it would be more satisfactory.
