Both sides are Apple, fully updated, expert user, in close proximity, good charge, blah blah blah. Maybe it’s me… or… just maybe… Bluetooth does have room for improvement.
In my experience the W1-equipped headphones all work flawlessly, pairing is instant. The only thing that is still annoying is the difficulty of managing multiple devices & headphones, when the built-in 'right thing to do' (like connecting to the last used device) can conflict with your real intent.
