EP-T32 Right headphone not working at all

Just purchased the EP-T32 wireless headphones. I have fully charged the case but for some reason the right headphone is not working at all. The LED light on it does not turn on at all the way it does on the left one. It seems as though it cannot hold a charge at all. I tried resetting but the right headphone is just completely unresponsive.

What should I do?
