FiiO JM21 Portable High Resolution Digital Audio Player (Light blue)

Great little dap, cheapest one out there, great sound, all the whistles and bells included, wi-fi and Bluetooth work perfectly unlike on my A & K £700 machine. Maybe battery life could be improved but it’s ok. If you are used to using your phone for music you must try one of these!!

The clarity of this ADP is exceptional,having had quite a few MP3’s and Apple product is outstanding given the price of this player a no brainer…just purchase try and you always have the choice of returning…but you won’t!Brian,

It's decent enough. Feels well made, light, fits in the hand nicely.I sent it back though, as it didn't feel like it had the juice for some of my IEM's, and it had no hope of running the 300ohm HD660S2, especially as I could watch the battery drain whilst powering them.But, for low impedance, low sensitivity kit it's probably fine.I upgraded to the M21 and it's night and day, M21 is simply an upgrade in every department.

Previously ordered a hiby and was bitterly disappointed with the sound quality and how small it was. This is the business it's great value, sounds superb, and my only real criticism is the internal memory could be better as most of my music library I now use on Spotify so am not able to store most of it. But apart from that I'm 100% happy

I have rated this device at 3 stars not in order to imply that it is mediocre but only that it does not fulfil my personal expectations for a DAP. A few years ago I owned and enjoyed a FiiO DAP and based on that experience I had high expectations of this device I terms of usability. Only some of which were met as I try to explain here.Press reviews of the JM21 are generally positive about the build quality and, of course, the sound which at this price point is very good indeed. It is a nicely produced device that feels good in the hand, has a solid, slightly weighty feel to it and two headphone outputs (although I don't have balanced 4.4 headphones so couldn't sample this aspect). In addition, a very nice, thoughtful production detail is that it arrives with a fitted, clear silicone backside case and fitted screen protector. What's not to like.But, while admiring almost everything about this device and, bottom line, the sound output is terrific, I found much to disappoint me in the user interface. This feels too complex, occasionally confusing, awkward to navigate, and generally seems over featured (for example I have no need for a VU meter). Too often I could not easily backup to the choice point I was at beforehand so got lost or arrived at a choice that was unexpected. For me, in regular use a good DAP should provide simple and reliable methods for locating tracks, albums, etc. and going on my experience with the early model FiiO that I once owned that is what I expected here.I have spent quite a few hours uploading files, trying out the various functions, editing metatags etc. to help with file organisation but I have come to the conclusion that the interface for managing music files is it weakest feature if, like me, you want good quality sound with a straightforward play-me-this-music-now interface. Other devices on the do this although the price point of the JM21 is a key, and important, selling feature. Also, this is a device based on Android so some of the features that you will find here look like more mainstream computing resources and some users may well find these useful (e.g. the ‘safe’ folder) and because it has WiFi internet updates are routinely notified.Having said all this I do not want to diminish the quality of this device. It is great and for the money you are getting a device that will play your music to a quality level that may cost at least a hundred pounds more (assuming you are using a high quality file format in the first place). It would certainly suite users who really want to drill into some of the subtleties of managing music files … and for whom a VU meter might be a useful tool! In other words this is a device that would please that school of users known as audiophiles, an audience that is FiiO’s main focus these days.Note: (i) I have no comment about battery life. It lasted quite well while I was using it. Some reviewers have reported that it does not last as long as specified, but of course there are many usage variables at play for battery usage. (ii) My comments are mainly based on the use of the Pure Music Mode. Android Mode also provides playback tools. (iii) Online help for the device (what we used to call a User Manual!) seems limited.

Just pure sound excellent depth and clarity

I bought this player a few monthes ago. Now it does not turn on. Show an empty battery and does not charge any more. I tried different chargers and cables.

Great DAP. Runs smoothly and just gets the job done of supplying music on demand.
