My new X4s went totally dead and would not accept a charge from a MacBook PRO USB3 port (like it did prior). So I plugged them into a wall-cube, and they would not accept a charge. Then I re-tried the laptop port, and still would not charge. As a last resort, I tried a Garmin 5V wall cube, and the X4's charged, but the indicator light stayed red. Digital-woman says 100%, and I used them for half an hour successfully.
Question: should I be concerned that the indicator light does not turn green? Has the battery been compromised in these headphones that are only 1 week (and 2 charging cycles) old?
