Lossless is MEANINGLESS because Bluetooth audio itself is a lossy compressed stream. How are Apple going to market lossless streaming to Airpods, when such a thing is technically impossible?
There are lots of hardwired devices ready to playback in hi-res via phone or Mac, surely. And AirPods Max support spatial audio already and are apparently good quality.
I would expect the future of the H1 chip's audio streaming quality to soon be much better than Bluetooth.
