I very much understand how it doesn't work in wired mode. What you seem to not understand is the effort that Apple has taken to make regular, compressed audio sound amazing, without needing to use lossless. I think the only reason they are upgrading Apple Music to lossless is just because of the competition. If you've bothered to watch some of the exceptional reviews about these headphones and their competition, you would understand what they have accomplished. Its comparable to what they are doing with cameras on iPhones. No, the camera on an iPhone is not as great as some of the competition. But what the software does makes the photos look incredible. This is what computational audio accomplishes.
If you are a recording artist and need open-back headphones, these are not for you. For everyone else that wants a pair of over-the-ear headphones that give a remarkable listening experience, look no further.
