Why aren't my JBL E40BT turning on?

Why aren't my JBL E40BT turning on?
I recently got a pair of JBL E40BT, and today decided to use the BT function. The thing is, it won't work at all. When I plug it in to charge it, it flashes a white light very rapidly, when I take them off the charge and press the BT button, nothing happens. Any idea what I can do?

Did you find the reason ?
