I have had these headphones since August and I can say that they are the best purchase I could have made compared to what I heard from acquaintances about other more popular companies whose headphones cost 50+ euros. However, after hours of gaming or watching movies (3-4+ hours), they can be a little uncomfortable on the ears, which is understandable. Other than that, I would definitely make this purchase again without hesitation.

Excellent sound and microphone quality. The material, although entirely plastic, appears sturdy. Comfortable, they fit perfectly without leaving extra space in the ears. Time will tell how long they will last.

They were purchased with the offer that was running (-55%) at €17.99. I believe it is impossible to find something more VFM for this money.
The biggest advantage of these is the low impedance they have (16 Ohm), so they can be easily driven by mobile devices that use batteries as a power source (XBOX/PS controllers, mobile phones, etc).

I bought the headphones a few hours ago, so I don't have a complete opinion yet. However, I can say that what impressed me (and somewhat concerns me) is their weight. They are very lightweight and give you the feeling that you're not even wearing them!
The sound also impressed me. The bass is incredible!
I don't have a well-formed opinion about the microphone. I tried the mic test on Discord (which I'm not sure how accurate it is) and it had interruptions. Then I made a call with a friend and everything worked fine, without interruptions.
I will return in one or two weeks with an update.

User of the headphones for about a year now. Good sound, didn't expect it for the price. Good build quality, although the plastic bothered me a bit (but what can you expect from a headset that costs 35-40€). The reason I gave it 4/5 is because the microphone volume decreased and doesn't go up anymore (it started decreasing about a month ago), but I am satisfied enough with my purchase. It's the headset for "casual gamers" and not for "competitive gamers". It's worth the money and more.
