Poweramp: "The music player software with the best user experience", the interface is simple and clear, the functions are comprehensive, and the supported formats are also comprehensive. The supported music formats include ape and other lossless formats, the playback effect is excellent, and the operation is very good. It's simple, and since it's commercial software, you can easily get official technical support. However, the official version costs $4.99, which is equivalent to about 31 yuan. The cracked version doesn't last long and is annoying. (If your English level is sufficient, you can go to the official download address: /)

Playerpro: Free, with a relatively beautiful interface. However, I personally feel that overall it is slightly inferior to Poweramp.

Disadvantages: It does not support lossless music formats such as ape and flc. (Official download address: /)

RockBox: The depth of the stereo sound can be adjusted. The setting operation is very complicated, but it should be able to meet the needs (http://www.rockbox.org/). However, because rockbox is open source software and the official does not release the compiled version, various compilations are very confusing, and there is no official support for automatic upgrades. Furthermore, the compatibility of rockbox is quite poor. You have to find a compiled version that matches the resolution of your phone. In addition, the operation of rockbox is complicated and inhumane. Some strange problems may occur during use, leaving you helpless and without official support. However, this software is also very powerful and the playback effect is first-rate.
