More than complete connectivity
Shanling's M5s personal music player offers particularly complete connectivity, allowing you to scan most applications. Thus, DAP takes advantage of WiFi by integrating DLNA and Airplay protocols, and allows the import of audio files from music streaming services such as QQmusic or Tidal. Firmware updates have also been simplified, as they can be performed simply via WiFi.
It also benefits from a Bluetooth module supporting LDAC, aptX and AAC technologies. These advanced technologies make it possible to offer a high quality listening experience while enjoying the convenience of Bluetooth. Thus, Sony's LDAC codec allows high quality audio files to be transmitted in 16bit 44.1kHz without damaging the signal, even in 24bit 96kHz with slight compression. Qualcomm's aptX supports 16bit 44.1kHz files with slight compression, for a bandwidth of 352kbps. It should be noted that Bluetooth is bi-directional and will therefore allow the DAP to function as a player or transmitter, to stream your music directly to a Bluetooth device or speakers.
On the physical connector side, there is a 3.5mm Jack connector and a 2.5mm Jack connector. One is the balanced audio output, the other is unbalanced. The USB-C connector allows it to load the DAP or transfer files to it at the same time. As it is a bi-directional connection system, it also allows the M5s to be used as an external DAC.
