They have fantastic sound with very satisfying bass and noise isolation. However, the build quality and plastics are of very poor quality!!

The plastics that hold the headphone under the valve that allows rotation cracked after less than a month of use. I put insulating tape around that area to hold it and prevent it from breaking, but the damage was inevitable. After 6 months of almost daily use, one speaker stopped working and a few days later, the right valve completely broke. It was no longer held by the insulation, only the internal cable was keeping the speaker attached to the headset. I glued it with silicone glue, but lost the ability to rotate. A few days later, the left side also broke. I had reached my limit. I threw them against the wall with force and then into the trash.

I should note that until then, I had never dropped them or hit them. This breakage was due to the opening I had to make to put them on my head.

Furthermore, the microphone is very short and is located far from the mouth. From the beginning, the sound quality of the microphone was mediocre and after a while, it reached a point where I could barely hear myself or not at all.

I give two stars for the comfort and good sound they had initially. In this category, there are much better options for the same price.

Very good headphones, I have them for only 1 month, but after several hours of wearing them, they make a small sound that doesn't bother me much anymore. I don't think it's worth 50 euros, I got it for 30 on Black Friday

Personal opinion, it is perfect except for the construction quality but I would recommend them with closed eyes

I think it is perfect for its price at 40€.
Quality-wise, it has good sound and incredible noise isolation without tiring you out too much

In my opinion, these are some of the best headphones. Before I bought them, I didn't care much about the sound quality I was hearing, but after 3 months, I can't listen to anything without them. They are also quite durable over time. I, who burn through headphones quickly, have had them for 11 to 10 months and they still look like new. They also have a volume wheel and a microphone mute switch, which is good. The microphone is great and you simply forget about it, and the headband doesn't hurt your head or ears and is very convenient.
The best.

Update: 11/1/2021: During the summer of '20, the leather started to completely deteriorate, tearing everywhere, and the parts that held the earcuffs broke a bit, forcing me to tape them with adhesive tape, and the right earphone didn't always work... I switched to Corsair HS45 Surround, now I find these useless... I suggest staying away, with the same money you can get something more reputable like Razer or Corsair.

Guys, don't hesitate, get them with your eyes closed!!! TRUST has done an amazing job with its Gxt gaming series! It's a product that other companies would inflate to 60-80 euros! Tremendous!
