Do me a favor and don't buy them, they are really terrible. There are countless other headphones, don't make the mistake, but they are truly awful

They are really worth it for their price and I highly recommend them for anyone looking to combine quality and value for money. They are the best for a gamer who doesn't spend the whole day on the PC, as your ears won't sweat from prolonged use, but they might feel a bit tight. On the other hand, I believe some people would like the sound to be a bit louder and perhaps more comfortable cushions or even more customization options for the headphones.

I have been using these headphones for 1 month. I bought them from an online store that also has physical stores. The price was 7 euros without shipping, as I picked them up myself from the store in Heraklion. I want to clarify that I am not a hardcore gamer, so I was looking for something cheap and satisfactory. I got what I was looking for. The sound is quite good with satisfactory isolation from external noises. The build quality is mediocre to poor, with the cheap plastic giving the impression that it will break easily. The microphone is the best part of the device. Very good. The cable is braided so that it doesn't wear out or get tangled, and it also has a volume control button. After 3 hours of gaming (which is usually my limit), they are quite comfortable and my ears don't sweat. The ear cushions are also quite good. The headset comes with a 1-year warranty. Overall, the headphones are quite good for 7 euros.

UPDATE: 29/1/2019 The headphones still work like the first day I got them. I don't use them heavily, that's the truth, but in the end, they are worth their (few) money.
