Does Apple Bluetooth deliver lossless audio or not?

I'm not complaining, and I really appreciate your answer. I have my answer now: Bluetooth does not transmit lossless audio. I'm guessing that when I send music by bluetooth from my iphone to my earbuds, that my iphone will compress (with losses, perhaps as .mp3 or similar) the lossless files located on my iphone so as to make it possible to send them by bluetooth. If that's the case, then I understand now. And if I want to listen to lossless files, I'll need a wired connection. No problem. I think Apple should make that more clear, but sometimes they try to simplify things instead of explaining them properly. The fear of confusing customers can actually lead to more confusion. A good tech writer, however, can explain without leaving out important information.

Thx, that's useful information. Wired earphones, however, can deliver lossless audio, I believe; so that's an alternative too in some situations.

Thanks. I can read the English language very well, but the statement"

"only that the lossless stream reaching an Apple device is possible to further be delivered to a Bluetooth audio device. In this case the lossless audio is lost during the Bluetooth transmission"

This statement does not make sense to me.
