Bluetooth doesn’t have enough bandwidth for true lossless audio. Apple appears to be fudging this issue somewhat, but when it comes to the full quality – what Apple calls Hi-Resolution Lossless – then the company acknowledges that it’s impossible.
Indeed, Apple specifically says that you can’t listen to Hi-Resolution Lossless (24 bit at 192kHz) on Apple products at all without an external DAC connected to wired headphones. The best Apple devices can achieve natively is 48kHz.
