Shanling is one of the oldest Chinese audio manufacturers, with a history stretching back 30 years. Music players have always been the brand's forte, and it is well-known for its M series of digital audio players. The product I'm looking at today is the M0 Pro, an updated model of the M0 that launched five years ago.
The M0 Pro is a music player distilled to its bare essentials: you get a screen, an ESS DAC, a 3.5mm jack, and a MicroSD slot for loading songs. While larger players like the Fiio M11S run a full-fledged instance of Android and integrate your favorite streaming services, the main goal with the M0 Pro is portability, so it misses out on internet connectivity in lieu of offline storage. The MicroSD slot lets you slot up to 2TB cards, so you can take a sizeable high-res library on the go.
