Lossless music is ordinary music with the same sound quality as ordinary genuine music CDs.

MP3 music, which is common on the Internet, is lossy compression, so the sound quality is worse than lossless music. The sound quality of lossless music is theoretically better than MP3. But now MP3 compression algorithm is more advanced, and the compression loss is not great. If you use an ordinary integrated sound card and a computer speaker with a price of two or three hundred yuan or an earphone with a price of about one hundred yuan, there is basically no difference between lossless and MP3.
