This little MP3 player is solution to all my problems. I had FiiO X3 Mk2 before and it was a bit heavy for normal se. However, M0s is everything I wanted - lightweight, tiny, SD-card storage and high quality audio (LDAC BT). The thing is actually smaller than typical BT earbud case! User interface is simple and intuitive and I was able to figure it out from the moment I powered it on. If it depletes the battery too fast, just play with auto-shutdown settings a bit. After I charged it for the first time, the next day it was showing low-battery, but after I played with auto-shutdown settings, there it is - battery is not even at half after 5 days of use approx. 1 hour daily. In any case, all my music listening problems are solved. :) Read more
Nice MP3 player, good sound easy to use interface Read more
did not take long to charge it up and try it - before I learned how horrible the UI is. truly a bad UI. so bad, I stopped even trying to use it after a few songs. the scroll wheel could be good but they dont use it well. there NEEDS to be more buttons and the screen has you swipe right to RETURN (in some languages, maybe; but not in western languages; we go left to right and to return, you'd go LEFT. wow, what a culture faux pas). ldac-hd skips on the ldac phones I have. I've tried ldac before and it does work on another transmitter. the usb slot has a flimsy plastic cover that is asking to break off. case is heavy metal. does not have to be heavy and does not really have to be metal. over priced, bad UI, sound quality is nothing special and bluetooth ldac is questionable. yeah, its going back.

Very small bluetooth player. Compact. Seem to be more clear than my old players. Read more
I really wanted to like this, but it just doesn't work for me. Not easy to use. Scrolling is very difficult and at times impossible. Volume dial is extremely sensitive. Each time you turn it on, the volume goes all the way down to zero. Also, I am really surprised by all of the reviews that state the sound was excellent; I found the sound quality on mine to be rather poor. Read more
Sound Output is great. But the user interface could be better. Since switching between the tracks is kind a crazy due to high sensitivity of the touch screen. At this price range, Wifi is missing!. Read more
I wanted a HI-Rez player but did not want to pay the rediculous prices that Astell and Kearnes or Sony wanted. Took a sample on this player and it has been a dream. It can take just about any file format. I would give it 5 stars if the battery life were longer. I prefer Flac files. As for sound- paired with my BOSE Q45 and Bluetooth it sounds amazing. Paired with a pair of wired in earbuds that also got on Amazon-$20 sound is incredible. All in all a great purchase Read more
Very nice small sized player. Bought this as a replacement for my venerable, still working, but aging FIIO M5. I first tried the Hiby R1, which was good sounding, but much too glitchy and lacking some basic features, like ability to use as a standalone DAC. The M0S is excellent sounding, in my opinion, on par with the R1, though with a different sound signature, and just works, to borrow a phrase! Connects well to my VW sound system, scales nicely with a variety of IEMs, and has an excellent price to performance ratio. Very happy, so far, with the M0S. Read more
