In June 2021, Apple Music is getting a big update, and it's free to all subscribers. The entire catalog of over 75 million tracks will be available in a lossless audio format using ALAC (Apple Lossless Audio Compression), starting with 20M tracks and expanding to the entire catalog by the end of 2021. Eventually all tracks will be available in a hi-res lossless format at a maximum of 24bit and 192kHz. In addition, some tracks will gain Dolby Atmos support, which can be played with lots of Apple and Beats headphones.
You'll see labels on on albums that show you which formats are available.
But not everyone will be able to enjoy these formats; you'll need specific hardware for each of them. (And software: you have to have your Apple device updated to iOS 14.6, iPadOS 14.6, macOS 11.4, or tvOS 14.6 in order to use these new formats.) Here's a simple breakdown of what you need to use these new formats.
Apple Music Lossless
Apple Music Lossless uses the ALAC (Apple Lossless Audio Codec) to retain all the information in the original CD-quality master. It starts at 16 bit, 44.1kHz and goes up to 24-bit, 48 kHz. No bluetooth device, not even Apple's AirPods, can decode this format, so you'll need wired headphones.
To enable this format on your iPhone or iPad, open Settings, then Music, then Audio Quality and choose between Lossless and Hi-Res Lossless for cellular or Wi-Fi connections. You'll also have to go into Settings or Preferences on a Mac or Apple TV to enable this feature. The iPhone has a built-in DAC that support 24-bit, 48kHz so you can use a pair of Lightning headphones. The 3.5mm port on the Mac also supports 24-bit, 48kHz.
Additionally, Apple's 3.5mm Lightning headphone adapter includes it's own DAC that supports 24-bit, 48kHz so high-end wired headphones will work. However, the Lightning to 3.5 mm Audio Cable that Apple sells for the AirPods Max doesn't support Lossless streaming.
Supported listening devices: Wired headphones or speakers are required. Of note, none of Apple's AirPods or Beats wireless headphones will support Apple Music Lossless. Even the AirPods Max when plugged in via a Lightning cable won't work, as it only accepts analog connections and then re-converts into digital. HomePod does not support Apple Music Lossless.
Apple Music Hi-Res Lossless
High-Resolution lossless audio is a step up from the standard CD-quality lossless format. It goes all the way up to 24 bit at 192kHz. It has the same requirements as regular Lossless but also requires external hardware capable of handling 24-bit audio up to 192kHz, such as a USB DAC or receiver. And you'll also need a USB-to-Lightning dongle for your iPhone or Mac.
Supported listening devices: The requirements are the same as with Apple Music Lossless, but you'll need your wired headphones or speakers to be connected to an external DAC capable of handling 24-bit 192kHz audio, which is in turn connected to your Apple device. HomePod does not support Hi-Res Lossless.
It's unclear how many tracks will be available in Dolby Atmos, but many more Apple devices are supported. Every AirPods or Beats product with an W1 or H1 chip in it will automatically play compatible tracks in Dolby Atmos, as will the latest iPhones, iPads, and Macs. You can force it on for other headphones by opening Settings > Music > Audio and changing the Dolby Atmos setting to Always On.
Supported listening devices: If you have any of the following headphones, Spatial Audio will automatically be engaged when a track with Dolby Atmos is played. It will also automatically play from the internal speakers on the latest iPhones, iPads, and Macs, and you can force it on for other listening devices through the method above. You must have your Apple TV hooked up to an audio device with Dolby Atmos support (or use AirPods).

Spatial Audio appears to be limited to Apple devices, however, as Apple Music on Android will not support the format, even when using AirPods.
Apple Digital Master
If you see the Apple Digital Master label on an album or track, you should know that it's just a rebranding of the old Mastered for iTunes feature. It has nothing to do with the output format of the track, it's just a way for Apple to promote tracks that have been encoded directly from the 24-bit studio masters. Apple explains it like this:
By starting with the best possible masters we are able to offer our Apple Music and iTunes customers the highest possible quality audio. Our latest encoder can take advantage of every bit of the high-resolution masters that engineers are creating especially for us. The results, both for streaming and download, are virtually indistinguishable from the original 24 bit studio masters.
You don't need any special hardware at all to take advantage of Apple Digital Mastersâ€”it's all about Apple creating its files starting from a really high quality source, that's all.
