I have the QC35 II and they are incredibly flaky with connecting to multiple devices.
FWIW, I love my Airpods Pro and it's insane that neither Sennheiser nor Bose could beat Apple to the punch with something that works as well as those do. That being said, my Airpods Pro aren't without issues: they seem to hate my iMac. Not even the Big Sur update could change my Airpods' aversion towards reliably connecting to it.
