When I bought them 2 weeks ago, there were no reviews, so I literally went blind with these headphones. The construction seems to be of good quality with a metal frame, which I didn't expect from 35 euro headphones. They are also comfortable after hours of gaming and the cables seem to be of good quality. As for the sound, it is average, it didn't bother me in gaming, it's fine for transmitting the sound source and I don't think you will encounter any problems. However, when I tried to listen to music with them, the sound was terrible and very muffled, because it only captures bass and high frequencies, leaving the midrange lower. It also captures some very high frequencies in the music, resulting in an annoying buzzing noise. As a microphone, the sound is okay, but it doesn't isolate the environment at all.
Durability is what will determine if these headphones are worth it or not. If they last for 2+ years, then they are worth the 35 euros, if not, go elsewhere. It's still too early to talk about durability as I've only had them for 2 weeks. From their construction, they seem like they will last, but you never know. I will update regarding how they hold up in the coming months/years (hopefully).
Edit: 5/1/2023 Half a year+ later, they are functioning normally. The cable comes out relatively easily, but it might be because of my 7-year-old controllers (to prevent it from coming out, avoid abrupt movements). Other than that, they are exactly as I took them out of the box.
Edit: 18/4/2023 I am changing my rating to 1 star because one day while I was playing, I stopped hearing the voices of my friends and almost half of the game sounds, and it has been like that since then. Go elsewhere, because while the external construction seemed to be of good quality, the internal one was similar to 10 euro headphones.
