Hello, Burleh.

Thank you for using Apple Support Communities.

From what I understand is that you want to know how many devices the AirPods Pro can be connected to. What you're experiencing is expected behavior. The AirPods Pro can only be connected to one device at a time. However, AirPods are connected to your iPhone and Apple Watch at the same time. Sound automatically switches between them: Connect and use your AirPods and AirPods Pro
