Anker broken? or how to reset

Since some hours the Anker seems broken. It is fully charged, Several devices can connect as usual without troubles. But there is no Sound at all. The led is bright blue, I get the red light, when the charger is connected. But there is absolutely no response if I press any button.
Broken after 4 month? How to reset if no button is responding?
