What is the easiest way to transfer music from Mac to iPhone without syncing

Finder is a built-in file manager for macOS from Catalina (10.15) for managing iPhone data.

First, store the legal MP3, AAC music files in the Mac's Music files, etc., then check the storage on iPhone to make sure there is enough space and turn off the sync library.

Next, use USB-C/Lightning cable to connect the iPhone to the Mac and select trust, enter the password, and then open the Mac's Music app to import the music files into the library, and then use Finder to sync the music files.

Now, open Music app on Mac to import music files into your library, then click iPhone in Finder and set 'Sync Music' in Music tab, finally open Music app on iPhone, check and verify the songs can be played offline in Library > Songs.
