The sound of these headphones is excellent for their price with strong bass for their type. Because they are semi-open type, they do not have great sound isolation with the environment. What I especially liked is their stereo, especially in gaming, it helps a lot. They also have very good reviews on well-known audio sites. I have had them for 2 months and have not seen any quick wear on the materials, as for this price, that would be their weak point.

The sound quality is incredible for 40 euros (33 + 4 shipping) headphones and they are quite comfortable for any use. They are semi-open, so they don't isolate the sound well from the surroundings, although they are not advertised for that, so for me it's not a deal breaker. The packaging comes with 2 sets of ear cushions and 2 cables, a small one and a large one. A big plus is the long cables that help a lot with mobility. It's good that there is plenty of documentation on the internet for mods and it's an affordable solution. The next mod is to add a jack port instead of a cable.

They have one big but:
The build quality is poor, but the good thing is that they are easy to repair. The small cable - where the larger one attaches - broke within the first 3 months of use, but the cap can be easily replaced, so with a new soldering, they worked normally. Instead of a cable, it should have a port that directly attaches to the headphones (like the AKG K240) to prevent the cable from breaking so easily.

Semi-open with a very good soundstage ... very clear but bass-heavy... not suitable for mix-mastering ... but for listening to music, it is a pleasure... at a very good price...
