I am satisfied with the purchase. I advise everyone. An excellent product for its price. Pros: och. convenient, you take it out of the box, insert it into your ear and it has already turned on and connected to the phone., sound is normal control through the smart watch widget is very convenient. Cons below: after a while they pop out of the ears. maybe it's the specific features of my ear structure)) disabled the touchpad, tk. when you adjust the earpiece in your ear (see paragraph above), something constantly happens. sometimes during a conversation on them, as in a headset, there is a slight desynchronization between the left and right ears and the sound is a little strange. But this rarely happens.
