Overall, disappointed so far. Let's see what happens next, suddenly play out? But if there was an opportunity to return and receive money, I would return it. Pros: Good construction. Confident reception of a blue tooth. They sound good when used in a quiet room, but my old Fischer Audio Con Motos outshine them to the fullest. Cons below: Ears hurt when worn for a long time. In addition, when used outdoors, low ones are lost, and due to the tight pressure on the ears, you can hear your own steps, which drown out the music at a low volume.
