Pros below: The sound is balanced, the level is KZ ED9, the microphone is very good. Cons: For this money one of the best (if you do not take into account Ali)

With its pros. Good sound, they sit comfortably in the ears, I'm happy with everything, we'll see how long they last Its cons: The plug that is inserted into the phone is not the same as in the photo, it is bent at an angle of 90`, not critical, but I would like reliable information in the photo.

Has pros: Done well. Just what was needed for a spare set. In case of discharge of bluetooth headphones. Cons: The sound is quiet, not adjustable. Near extraneous sources of noise, audibility tends to zero.
