Fantec SHS-221BT not charging?

    Fantec SHS-221BT not charging?

    I recently bought the SHS-221BT headset (via Amazon) and after receving the first one, had to send it back as it was not charging. When connecting it to the computer via USB in order to charge, the red LED stayed red for about 2 seconds, then flashed one time and then stopped glowing. The headset wasn't charging either, as after having it plugged in for 12 hours, it would not turn on and seemingly did not charge. When plugged in to the computer, however, it could be turned on and could connect to any Bluetooth device.

    After sending it in, I requested a replacement, that arrived today and it has the exact same problem.

    Am I doing something wrong? It seems very unlikely that both have the exact same error. Tried charging via another computer, a laptop and a AC adapter that lets you charge USB devices on a regular outlet and nothing worked, got the same error all the time.

    Any help available?
