We really need someone other than Qualcomm & Apple to come up with lossless Bluetooth audio codecs.
TBF the whole Bluetooth audio situation is a complete mess
Wait, did Apple implement its own codec? I thought even the Airpods Max used AAC, which is lossy.
As for Qualcomm, only aptX Lossless is lossless and I'm not aware of many products supporting it (most supports aptX HD at most)
The newer H2 SoC AirPods support ALAC, Apple’s lossless codec; however, their phones don’t yet support it, so the only way to use it is with the Vision Pro.
AFAIK, ALAC will not be actually lossless over bluetooth for the sames reason LDAC can't be lossless; there simply isn't enough bandwidth. That doesn't mean that it won't sound great or perhaps work better than LDAC.
It runs over a 5GHz connection, not a 2.4GHz connection like bluetooth.
Oh, so they aren't on bluetooth at all? That is an entirely different story, thanks for the info.
Wait what? Do they not connect over bluetooth? Please don't tell me they made up more proprietary bullshit.
Yes, the protocol used is currently proprietary. That being said, so was ALAC at launch and they later made it open-sourced and royalty free.
