AirPods blinking orange as long as they are both in the case, one of the pods don’t work
Try wipe off the metal end of the problematic AirPod, and then used a Q-tip to clean the bottom of the case where the metal end of the AirPod made contact with the case. If this doesn’t work..well... contact Apple to advise that your product is not working properly upon receipt:
