Hi,
I bought my BNX60 headphones about a month ago, now it does not want to charge. Unfortunately, I can't remember if the battery was empty yesterday when I put it away. I measure 0.6mA current through the USB cable when I plug it in into the headphone. It does nothing if I press (for a couple of seconds) the play/multifunction button, but the ANC LED is lit blue if I turn on the ANC functionality with the switch. What could be wrong with my headphone?

I've found the solution. I've disassembled the left cover and desoldered the battery positive wire from the PCB. After a few seconds resoldered it, and now it works perfectly. So cutting the power from the board ("hard reset") solved the problem. I think maybe the software in the microcontroller got frozen and needed a reset. It would be nice if the user could do this kind of reset without the need of soldering (for example a small normally closed tactile switch could do that). On the other hand, I really like the design of the headphone from a technical viewpoint, it was easy to repair.
