Airpods sound on the side.
I just noticed my right airpod sounded weaker than the left one. The thing is that it isn’t sounding through the main speaker, but the one on the side. What is wrong with it? How can i fix it?
Try a full re-pair, reset, and try again.
Start with Unpairing/"Forgetting" the Device:
Settings > Bluetooth > Airpods > Forget this device. Confirm it.
Put both Airpods in their case, charge them via Lightning for a few minutes (or preferably until the case is 100%). Unplug them. Open the case and hold the button on the back of the case for 15+ seconds or until the light flashes white. Hold them near your iPhone and see if the pairing screen comes up and pair them. If not, repeat until it does. But if you can't see the screen pop up, then manually pair within Bluetooth.
If it doesn't work, open a case with Apple Support here: https://support.apple.com/airpods

Also please let me know the Firmware Version if it doesn't work:
