I got them for 39 euros. There is nothing else for the same money that can be compared to them in terms of quality. Both in sound quality and comfort. These are the second ones I am buying.
Negative: The plastic that connects the ear legs breaks relatively easily, for example, mine lasted about 6 months.

First of all, the headphones have a CRYSTAL clear sound. Clear and powerful with decent bass. VERY light and comfortable and the microphone is very flexible so it won't get in the way. Speaking of the microphone, it is truly amazing. Clear, powerful and unlike most headphones in this price range, the voice sound is hardly distorted at all. Suitable for online games (e.g. PUBG, Fortnite, Warzone) due to its microphone and stereo sound that works as expected. Very high quality construction. Just don't rage on them, they sound good as they are... The environment doesn't cover them completely but some people find that convenient

I bought them from a well-known online store. They were so bad that I thought they were broken and I sent them to the service in the first month. They told me they were fine and that they didn't have any problems and returned them to me. I have had them for three months and the microphone keeps turning on and off randomly. Very bad product from Corsair, a waste of 80€

Unacceptable! They broke in 3 months without any significant wear and tear. They were not replaced supposedly due to misuse. 50 Euros is a shame for Corsair

I bought them for 30€ due to a discount. For the money, I think they are a good price. Overall, the construction is lightweight and cheap. The sound and microphone are fine.

I hope the cables don't break quickly. Their quality is quite poor.

I would like the microphone to be detachable so that I can wear them outside.

Edit:

Finally, the Corsair L. After 7 months, when I adjust the volume from the potentiometer, there is noise because it probably doesn't make good contact. I haven't broken them once. Also, when I mute them naturally, meaning when I raise the microphone, there is mute but with noise. Only two stars just because I bought them for 30 euros and the sound is good.

I understood that they are good headphones from the first hour I used them. Especially during long use, they don't tire you at all, and that is the most important thing for me. As for the microphone, it is equally perfect in sound quality and construction quality. Overall, these headphones are in the TOP 2 for my taste. I recommend them to anyone looking for good gaming headphones with a not so expensive price, they are a must for every gamer.
