If you call up the Apple Music app on your iPhone, iPad, Mac or Android device, you will find lots of information about the individual artists, albums and titles there. Certain symbols and terms have also been displayed for some time in order to briefly represent the maximum audio quality that can be called up. Under the respective designations are Apple Digital Master, Dolby Atmos and Lossless or Hi-Res Lossless. For the last two, I have compiled the most important information and links for further reading in this article.
If you tap on the icon of this description of the audio quality of an album or track on the iPhone or iPad, a small explanatory text will appear. For Lossless this is: Lossless format uses Apple Lossless Audio Codec (ALAC) for bit-perfect playback at up to 24-bit/48kHz.

In the support document linked above, you can find instructions on how to listen to Apple Music subscription's lossless compressed music on iPhone, iPad, Mac, HomePod, Apple TV and Android devices. In addition to wired speakers with digital-to-analog converters and similar accessories, you can also use Apple's own headphones.
