+I have never worn such lightweight headphones with "leather" support. They are so light that no matter how tightly you put them on, they simply stay on you and you have the feeling that they will come off with a sudden movement (but they didn't).

+Despite their lightweight and low price, the build quality is not bad - I would say it's average.

+Finally, I believe that the microphone is slightly better compared to others, but weak in sound input, as it requires +20db amplification (where if you put +20, "whistling"/interference starts in the sound), unlike other headphones of the same range where +10db is sufficient.

-1 Star is lost due to dissatisfaction with the volume, I expected and desired it to be slightly higher.
