"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.

FLAC is a lossless compression format. It will reduce file size but keeps the audio quality. So-called "high-res" format on streaming platform like spotify (mandatory fuck spotify here) are usually mp3 320kbps so heavily compressed and lossy, indeed.

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.

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
