Very good in terms of sound quality for their price. Of course, I got them for 6 euros + 5 euros shipping and so I would say it is a purchase worth it. The microphone is not very good but at this price you can't expect much. Also, it does not have volume control. They have very good sound isolation and are extremely lightweight and comfortable. However, the build quality does not inspire me at all, to the point that I think they might last maybe 6 months the way I see them. They just give you that feel. I must say that I also bought the 1more piston fit and while their only drawback is that they are a bit heavy in the ear and tire me after an hour of use, compared to the jib they have much better sound quality and overall construction. I enjoy listening to music with them and they are quite cheap. Also, the microphone of the 1more is quiet while at least the microphone of the jib is louder. So to be honest, I continue to use the jib because they are more comfortable even though I really don't know how long they will last. That's all...

I think the best bass + volume in the budget acoustic category. Crystal clear sound. I didn't expect it to be honest but it easily competes with well-known companies that cost a little more.

Very good headphones, they have very good sound quality and strong bass, I bought them for 11€, they are worth buying, I highly recommend them!!

Decent construction. Cable is quite long and thin. Powerful sound with rich bass. Time will tell for their durability.

Good sound for cheap headphones, with pretty good bass and relatively strong volume, but they broke (one of the two stopped working) around the 6-month mark.
