I still can not hear out of the right AirPod

Not sure what you have tried up until now however a reset is usually what works for me:

You'll need to unpair the headphones and reset them using the case.

Disconnecting and resetting wireless Apple AirPods:

1. Open the Bluetooth menu on your device and choose to Forget the Apple AirPods 
2. Return the AirPods to their charging case but keep the lid open
3. Hold the setup/reset button on the back of the case for 15 secondsResetting your AirPods is as easy as holding the Setup button.
4. Keep the button held until the light beneath the lid flashes amber
5. The AirPods have now been reset, restart your device and pair them as new
