My right Beats Studio Bud stops working as soon as I take the left one out of the case

Hello ,

Try resetting your Airpods --> How to reset your AirPods and AirPods Pro

if not work contact --> Apple Support 

I had this issue but with the left AirPod. I did everything (forget the device, turn off Bluetooth, reconnect, etc). After calling Apple support, their only solution was to mail in my AirPods for repair... This is what worked for me:

1. FORGET this device on EVERY device it's ever been connected with - Computers, iPads, Phones, TVs. Then, turn off all those devices. Then, start over on your preferred device.

I made an account just to share this. :)

Good luck!
