Why is that? The thing that terrifies me with less known brands is the quality of the DAC. I had so many shitty mp3 players before settling on ipods in 2003. Even today most laptops motherboard DAC are useless.
M0 is much lighter and cheaper and uses USB-C instead of a proprietary cable. The feature set is roughly similar (audio formats, USB audio, BT source/sink, etc.). It doesn't offer any media sync software, though. DAC should be good ("ESS Sabre ES9218P") but honestly I can't tell the difference between Apple's own 3.5mm-Lightning dongles and fancy audio equipment. At least it's not obviously noisy.
P.S. These players don't have very powerful CPUs, obviously, and this makes me wonder whether they can handle more complex audio compression formats (such as AAC encoding for Bluetooth) without cheating and using sub-optimal encoding settings.
