When connecting to my laptop, often I start to experience jitter (or robospeak) both on the receiving and sending side. As soon as I plug another wired headset in the problem is gone. When I experience this problem, none of the buttons work and I am not able to switch the Fairbuds XL off to try and restart it. The only thing that works is to remove the battery (hard restart). Most of the time, for the rest of this day after removing/replacing the battery it is fine again.
