I was using my headphones and they were on low battery. After I finished my workout, i plugged them into a charger. So i figured they didn't charge for some reason. So i tried again, but this time i plugged them into a different plug and also in my computer so i could keep an eye on them. No go. They will not turn on at all and won't charge. Not light blinking and can’t turn on. I follow one recommendation that was download the Bose updater in my PC, but when I connected to the USB the system don’t detect the headphones. Please help me.
