I picked up a pair of BFP at the Apple store earlier today. Immediately compared them to my APP, and they're great but I am having a slight hissing when either transparency or noise cancelling is enabled. Anyone else running / hearing this? I heard that the newer Airpods 3 also have this, and exchanging seems to help. Ill swing by tomorrow to replace these, but was a bit bummed. Other than that they seem great.
