I dont have to unpair the Sony's to pair them again. In fact pairing them between my devices is as simple as going into devices and choosing it. It then immediately connects. Probably takes an extra 2-5 seconds than my Airpods.
ok, looks like I misunderstood that part. My wh-1000xm3's behave as described. My readings of the reviews of the wf-1000xm3's made me believe that problem persisted.
