Normally the headphones will only charge when they are off, and the red charging light will be fully lit. Now however, my headphones will not charge while off (the charging light flashes and blinks erratically), but if I try to turn them on while plugged in, the bluetooth will turn on, and the charging light will light up fully. No matter how long I leave the headphones plugged in and on, once I unplug them they won't turn back on.

Quite a lot of wont turn on issues have been reported for this device. One solution is to remove the battery and plug back. This will likely invalidate any warranty so only undertake if outside of warranty and accept the risk. See other links to posts discussing this below.
