"On 17 September 2019, the Japan Audio Society (JAS) certified LDAC with their Hi-Res Audio Wireless certification."
Something something oxymoron. Bluetooth is trash, its why I still use wired whenever I can.

To my knowledge it's lossless in CD quality only, in high-res modes it becomes lossy
It's nearly lossess if you can connect and maintain a 990kbps connection, but it still doesn't have enough bandwidth to do it truly lossless. I think it would require 1411kpbs to be actually lossless. It is still better than any codec I know of for bluetooth as far as that does, but bluetooth just kinda sucks for that sort of application.
1411 kbps before compression. FLACs can go as low as 200 kbps based on the content of a file

Ignorant of the subject matter, but I ripped a bunch of CDs to FLAC some time ago. Would that not work for this purpose?
Ldac is a Bluetooth thingy, so my understanding is that flacs will be re-encoded on the fly when you play 'em on bt headphones with ldac.
Bluetooth has fairly low bitrate which also helps save power. The throughput will also vary with signal quality. It needs to somehow adjust to worse conditions, otherwise it will just keep cutting out. Streaming CD quality FLAC could probably be done over Bluetooth 5 2M PHY, but 2Mbps is just the physical layer. There's also some overhead. Perhaps just enough would be left, but the bitrate will also vary with the content. Not everything can be compressed much, while some audio can be compressed quite a bit.
Probably would work, but the reliability is also a question.
Anyway, just guessing. Perhaps the 3Mbps EDR could be used just fine.
Oh, Bluetooth 3.0 + HS could do 24Mbps. Sort of. It used WiFi to do that.

My favorite is most people are listening to already lossy compressed music that gets decoded and then recompressed in another lossy manner⦠I miss my cable sometimes.
In the end, I found I don't really care that much, since lossy Bluetooth works well enough for earbuds on the go, and good old cables are still available for more serious listening.
Plus, the truth is that most people can't tell the difference between lossy and lossless without doing A/B testing, and some can't tell even with that
