Tried turning them on right after opening the box, they didn't work. I tried charging it for 2 hours as per the manual, I saw the battery indicator flashing but after unplugging the cable, no response, finally I tried turning it on while charging and was able to connect, the phone shows indicate that the battery is fully charged, but they die when the cable is unplugged. I would even try to have them connect to the power bank but they got that annoying 'charging complete' sound every 2-3 seconds, please buy another model, this one has many complaints and I found that it does it's correct.
