Hey. A few years back Apple introduced a feature called “Automatic Switching” if all the devices are on the same iCloud account, when you’re done using iPhones and pick an iPad, it should switch automatically. Even if it doesn’t work, you don’t need to disconnect AirPods from iPhone to connect to iPad. While AirPods are connected to iPhones Just go to Control Centre on iPad, tap and hold Bluetooth so a list of available devices shows up. Then choose AirPods. They will connect to iPad and disconnect from iPhones. I do this all the time between my Mac and iPhone.
