The quality is decent. FM radio sounds great in stereo. The MP3 search time can be long if you have many folders on the disc, so it is better to burn all MP3s in root directory. It was able to read CD-R and CD-RW with no problems. Though playlists are not supported and searching is too cumbersome. A better idea is to have different CDs for different moods / types of songs so it does not matter which exact song you want to hear And for a different mood, swap the CD
However, it is not used in its full potential. It has 4 speaker output while only front door speakers are provided, so you have to install rear door or rear tray speakers and get them wired yourself, I think that will be a big boost to audio.
