This wireless headphones is old in terms of its charging cable the cable is very short and it is usb-b now there is no charger for usb-b. I tried charging the headphones, it's not working in charging and it's not turn on from the turn on button, so I am returning it as it not working.. I hope the replacement will have usb-c charging cable and a light indicator so I can know that it's charging when I plug it in to the charger
