Working AirPods Pro 1 with charging case and defective AirPods Pro 2 with charging case, haven’t used either of them for a while and confirmed functionality of 1st gen, unable to make 2nd gen work. Audio still transmits but there’s an awful hissing and static noise in the 2nd gen. 1st gen works flawlessly. Both forgotten and reset (to the best of my ability), no longer have apple care for either of them. Both use lightning as the charging connection.
