I use AirPods 3 left AirPod do not work but i put right AirPod in ear sound is coming from both side .what can I di

Greetings zin264,

If your left AirPod is not working, work through these steps:

1. "Make sure that your charging case is fully charged.
2. Place both AirPods in your charging case and let them charge for 30 seconds.
3. Open the charging case near your iPhone or iPad.
4. Check the charge status on your iPhone or iPad to make sure that each AirPod is charging .
5. Put both AirPods in your ears.
6. Play audio to test both AirPods.

If an AirPod still isn't working, reset your AirPods or contact Apple Support." If your left or right AirPod isn't working

We hope this helps!

Sincerely.
