3.Transferring files over AirDrop is also a very rapid way. This method allows transferring FLAC, as well as any music format. Folders are not allowed.
4.Same as AirDrop, tracks can be loaded directly to VOX player via File Share. Simply drag & drop files and folders to VOX Documents in the Music app.
Your music content will be available on a mobile device in a minute, without syncing with the Music library.
