There are three differences:

1. Different sizes. A song with standard sound quality is about 2-4MB. A song with super high sound quality is about 5-1MB. A song with lossless sound quality is about 1M m.

2. The sound quality is different. Music with standard sound quality doesn't sound too rough. Super high-quality songs sound more detailed. (for example, the sound of an accompaniment instrument) without compromising the sound quality sounds very clear.

3. The classification is different. Standard sound quality, ultra-high sound quality belongs to lossy sound quality. And lossless sound quality naturally belongs to lossless sound quality.

Extended data:

There are three common lossless formats: ape, wav and flac, and aac can only be considered as high quality. Its advantage is that all lossless formats are essentially wav compression, and will be turned back to wav when playing. Therefore, playing wav directly helps to save memory and is smoother. But the disadvantage is that the file is too large, generally more than 3 megabytes. Ape and flac are relatively small.
