I'm selling a digital audio player I purchased on AliExpress that has received high praise for its sound quality. It does not have Wi-Fi or Bluetooth. It also doesn't have a USB DAC function or a touchscreen. It simply plays audio files, but the sound quality is outstanding. Please refer to overseas websites for more details. In my subjective opinion, the sound quality is similar to that of a HIFIMAN DAP. Although not shown in the images, the original box and accessories (cables) are included. Returns are not accepted to prevent product substitution. Please be aware that, as is common with Chinese products, there may be some quirks in its operation. Thank you for your understanding.
