SHANLINGM0s MP3 Player with Bluetooth Hi-Fi Lossless Sound Music Player Portable Digital Audio Player (Without SD Card)

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. :)

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

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.

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!.

I really liked the concept of this small (really small) MP3 player. It promised a lot of functionality. I have a large collection of MP3 music files on MicroSD cards. I have them sorted by category, with a certain genre of music on each one. This player, which takes MIcroSD cards, seemed perfect for my needs. Things started great. I inserted a card and the player recognized all my folders and made it easy to navigate my music. Initially I had no problem listening to music via the (enclosed) wired ear buds and my own Bluetooth ones. After less than a day, however, the player no longer connected to my Bluetooth ear buds. Nor did the wired ear buds work anymore either. I did all the troubleshooting I was capable of and came up empty. I am sad because the concept of this MP3 player had a lot of promise for my needs. Perhaps I got a lemon, but, whatever the reason, I have an unusable player.

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.

Ok, so this isn't as easy as putting a streaming app on your phone and pressing play. That said, it isn't that difficult to figure out most things if you spend a little time with it. I haven't spent much time getting it to be a good useable player, but I like it so far, and I'm looking forward to figuring out more of the features as I go. I ordered this because I have a full high resolution audio stereo system in a car that I'm restoring and I'm really looking forward to trying this out with that system! And I want to get away from my relying on paid streaming services.The sound quality of this player is very good, especially considering the price point. The screen, for how small it is, has a crisp and clear display. As others have said, the controls are a bit sensitive and sometimes can be hard to scroll in a controlled fashion.The first music files I used were sorted alphabetically by artist/album/song so if I wanted to play something on random, I was only able to play one album at a time. A simple reorganization of my files, putting all songs in a common folder, allowed a full random play, which is what I prefer. The nice thing is you can set your playlists up however you want.One glitch I experienced with the player is when I paired it to my car. If I didn't have it plugged in to charge the player would power off after about a minute and then the music would stop. That was very annoying but keeping it plugged in is an easy work-around so I've been doing that.Something that was a bit more difficult is pairing to earbuds. I have Samsung Buds2 pro's that I've been unable to pair with the player. When that didn't work I tried my older Wyze buds pro and was able to pair those. There is probably a way to get this to recognize the Samsung buds, but since I have ear buds paired I haven't put much more time into figuring this out, yet.I have had a couple of times where I was unable to bring the display to its "home" state by holding the screen, as it is supposed to do. At least one of those instances I think was due to the player trying to play an album that was in an incompatible music format. While attempting to play the incompatible files it was in a constant state of switching songs, so I think it was just not in a rest mode long enough to allow the long touch of the screen to bring it to home page. When that happened I just powered off the player and when I powered it back up I was able to navigate as usual.So, sure, there have been some glitches that I mostly consider the learning curve of figuring out the player. Even with that in mind I'm liking the player
