AirPods Pro problem with sound

Hello zawiszadark,

Thanks for reaching out to Apple Support Communities. We see you have some questions about your AirPods not playing sound as you expect, and we'd like to help. From here, let's make sure everything is balanced as it should be by going to Settings > General > Accessibility > Hearing, adjust the balance slider for left and right channels by keeping it in the middle.

If that looks normal, and restarting your AirPods doesn't help, try resetting them, to see if the issue remains: How to reset your AirPods and AirPods Pro - Apple Support

"You might need to reset your AirPods if they won't charge, or to fix a different issue.

1. Put your AirPods in their charging case, and close the lid.
2. Wait 30 seconds.
3. Open the lid of your charging case.
4. On your iPhone, iPad, or iPod touch, go to Settings > Bluetooth and tap the More Info button  next to your AirPods. (If you don't see your AirPods in Settings > Bluetooth, just go to the next step.)
5. Tap Forget This Device, and tap again to confirm.
6. With the lid open, press and hold the setup button on the back of the case for about 15 seconds, until the status light flashes amber, then white.*

7. Reconnect your AirPods: With your AirPods in their charging case and the lid open, place your AirPods close to your iPhone, iPad, or iPod touch. Follow the steps on your device's screen.

8. AirPods can be associated with one Apple ID. If you want to use AirPods (3rd generation) or AirPods Pro that someone else has used, they first need to remove the AirPods from their Apple ID.

* When you reset your AirPods, the settings for your AirPods also reset. You can change your settings again."

Regards.
