Black crap.
Very bad sound and very bad microphone.
Also, the cable is a joke, it doesn't inspire any confidence.
For me... stay away. A thousand times better with 2 euros more for the "Xiaomi Mi Piston Basic Edition" which I have tried.

3 months lifespan. One earphone suddenly stopped working despite careful use. I was swayed by the comments and chose them. In order to get the warranty (as they say because it's not certain), you have to send them back at your own expense, which is obviously impractical. I have never experienced this with any low-cost brand of earphones. All of them exceeded the usage time.

Very lightweight, comfortable, and with a perfect fit in the ear, without causing fatigue even when worn for long periods of time. They don't easily come off with movement. Their sound is more than satisfactory for their price. Clear sound with rich bass and good isolation from external noises. Very good sound quality for conversations with both speakers, without distortions or interference. I have had them for over a year and they withstand regular use. The cable gets tangled a bit sometimes, but at normal levels, which is something you can't avoid with any wired headphones. A very good purchase for their price. Recommended!

I am the owner of these headphones for 4 days and they are simply perfect. They have good sound, nice bass, perfect sound isolation, and they don't break if you take care of them without pulling them. For now, I am extremely satisfied with the 5 euros they cost.
