I've used these about three times, but I've only ever used earphones before, and the fit in my ears feels uncomfortable, so I'm selling them. The charging cord, etc., has only been opened and not used. The headphones themselves have no scratches and are in very clean condition. It's a color you don't see very often. The urbanista MIAMI is a wireless headphone with a total playback time of approximately 50 hours.

Furthermore, it also features an ambient sound mode (external sound input), allowing you to hear surrounding sounds without lowering the volume or stopping the music.

There are control buttons on the housing, allowing you to easily play, pause, control tracks, and operate the active noise canceling.
