Right earbud flashing while in case and not working

So I have the sesh evo wireless headphones and out of the blue randomly the right earbud started acting weird. While it is in the case the red led flashes but when taken out of the case nothing happens except for a constant faint blue glow on the led. It is completely unresponsive to anything I have tried to do. If anyone knows how to fix this it would be greatly appreciated.
