There is lossy compression. There is a rather old codec (SBC) at a few different bit-rates, and a couple newer better codecs from the last 10 years (aptX, AAC, ?). Apple does have the control to make sure better codecs are supported and used. It can be pretty hard to determine and control what codecs are supported and which one is used, this is almost always hidden and never mentioned anywhere.

Most audio you listen to on a mobile device is compressed already is not extracted and compressed a second time. > Apple does have the control to make sure better codecs are supported and used. It can be pretty hard to determine and control what codecs are supported and which one is used, this is almost always hidden and never mentioned anywhere. Nonsense. Few developers want to add the complexity of shipping and supporting their own audio decompression inside their app so they just use the ones Apple supports. There are exceptions, FLAC for example isn't supported by Apple, but I believe FLAC takes too much bandwidth to work over BT regardless.
