JadeAudio/FiiO JM21 Android 13 Hi-Res Music Player MP3 with Snapdragon 680, Bluetooth WiFi USB DAC 12.5H Playtime (Sky 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!!

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.

Great quality, easy to use especially in amdroid mode, nice clear screen, lightweight, keeps charge well, shame doesn't do android auto

Absolutely fantastic bit of kit

I was always interested in DAPs, but having since long transitioned to full streaming, DAPs seemed too expensive for me, so I was using Smartphone + USB DAC. I am a Tidal user for further context. I was hesitant towards purchasing a DAP given my use case, but now that I have finally decided to go for a Fiio JM21, and very happy with it, I would like to list the advantages of DAPs if you're a streaming user only as I find relatively lttle content from this perspective online. The JM21 at its price point, really makes the investment worthwhile and I believe more people with my use case should consider it. - Undistracted listening: this has to be the primary reason, when listening from the phone, doesn't matter how much I actively tried, just by handling it, it was to easy to get distracted by an email, a notification, etc. Sure ther are way to manage this with software, but having a physical device dedicated to the one activity makes it so much easier. - Memory Card: with most phones not allowing SD cards, I can now have a huge offline selection, that I can take anywhere with me, especially considering the next factor - Pocketable form factor: I can now take my music a lot more easily on the go and on runs, and I can listen to my favourite IEMs while running! - Car audio: this one depends on whether you have an AUX port, but for me that I have, there is an improvement in the audio quality. Also much easier to take the dinky JM21, plug it in and go than using the phone - Bluetooth codecs: getting into niche territory here, but for example I have a pair of Oneplus Buds 3 that use the LHDC codec, not available on my phone - More battery: as much as people complain on some reviews I am perfectly satisfied with the battery on my JM21, I can still listen to music even after a long day, much more important when cosidering that a USB DAC would occupy the charging port of your phone.

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.

This is ok as a music player but can’t see the display in sunlight which is annoying. Took some time to work out how to use it but the sound is very good.

I fell in love with it after only a few hours. This is my fourth Fiio player and I mostly knew what to expect when I purchased it. For the most part I am very satisfied with the JM21. My disappointment is with documentation and support from Fiio (more on that at the end of the review). The size and weight of the JM21 feels comfortable. It feels solid like my other Fiio players (X1, X3, and X5). Those players have held up to heavy usage and survived getting dropped too many times and all of them are still functional. I can't in all honestly say that the JM21 is easy to get used to and easy to use because I have used a Fiio Android based player before and find very few differences with the old interface. That said, I didn't have trouble adjusting to the old interface so I don't see most people who are used to android devices having much trouble. I have never used the iOS so I can't advise on the difficulty for those who are not used to Android devices. I like that it came with at least a silicone case and a pre-installed screen protector. I ordered a second protector but passed on a better case. I had the leather case for my X5 but found that it made access to the edges of the screen difficult without a stylus. The technical details of the audio processing capabilities are a bit much for a review but I can tell a definite difference in audio quality when comparing the JM21 to that quality of music on my phone or on the no-name player I have been using. I have tested it with JBL 770 Live headphones connected with Bluetooth and with Status CB-1 headphones connected with a cable. An added bonus is that as unlike when listening on a phone I don't have to worry about the music cutting out if a text or call comes in. I have mostly been satisfied with the battery life. I recently listened to an 8 1/2 hour audiobook on the Audible app and maybe an hour of music using the Fiio app (without using a headphone amp). I used wired headphones for the music and the Bluetooth connection for the audiobook. Wi-Fi was only turned on long enough to download the book. At the time I started listening the battery had a 100% charge. After about 9 1/2 hours of use and sitting idle overnight there was still 34% battery power left. For some reason the player dropped to 9% over the next 11 hours while it was sitting idle. Hopefully turning on battery saver and using the "Enter Sleep" app that is pre-installed will help with that. I do not have the feature that turns the player off after a certain time enabled but will do so if necessary. The JM21 has Android 13 (customized) installed and uses the Google Play Store as well as Fiio's app store. This opens up options to use most any software you want. I use my player for listening to audiobooks and podcasts in addition to using it for music and have been able to install my favorite podcast app, a player for local audiobook files. The Audible app was preinstalled. The JM21 does have a micro SD port for expandable memory (up to 2TB). Even if I wasn't concerned with audio quality finding a modern phone or with enough storage to keep my music on it isn't possible. I have more than 400GB of music in FLAC format and over 100GB of music purchased from services that don't offer lossless files. iPhones and the newer Galaxy phones don't have the capability to expand storage with a memory card. I listen to a lot of music digitized from old albums or from independent artists that are not available on any streaming service so the extra storage is a must. Even if all of it was available streaming there is always going to be a time when Wi-Fi isn't available. I have heard the argument that I don't need carry all of that with me but if I get the urge to hear a song I don't want to have to wait to be able to move it from my computer to be able to listen to it so the storage is a must for me. I gave the player a 5 star rating only because 4 1/2 wasn't possible and I feel it is too good for a 4 star rating. My reason for wanting to give it 4.5 is not because of dissatisfaction with either hardware or software but for lack of support from Fiio. There is no manual available for the JM21 at this time. Yes, it ships with a quick start guide and there is a FAQ on Fiio's web site but they don't list all of the features. I needed to find a way to lock some of the side buttons when the screen is off. I have not been able to find how to do that in any available documentation. I finally stumbled across how to do it when looking for something else in the settings. As soon as I got the JM21 I sent a request to Fiio asking for an actual manual and got a reply that gave links to the quick start guide, the FAQ, firmware download, two different trouble solutions, and an apology for being slow because of a higher than normal volume of help requests. This also happened when I contacted support for a problem with my X5 player about six years ago so if you purchase this be aware that you will need to rely on third party information for anything that is not in the in the FAQ or quick start guide. The quality of the player itself, however, makes the lack of direct support and information from Fiio worth the trouble. If you are looking for an affordable portable player with sound that is equal to that of the high end, expensive players and better than you'll get from any phone give the JM21 a try. It's not perfect but I doubt you will be disappointed.

DAPen var mer än jag förväntade mig. Först körde jag med bluetooth hörlurar och det kändes hyggligt ok. Något bättre än jag minns MP3 spelare från 15 plus år sedan. När jag köpte till ett par IEM (Fiio JH3) så insåg jag vilket kap DAPen var. Är väldigt nöjd med kvaliteten på ljudet. Väldigt klart och tydligt över hela frekvensbandet.

Muy bien, cálida en todos sentidos por el precio.

É um leitor MP3 realmente excelente. Friendly , muito intuitivo, muito bom em te-lo nas mãos. O modelo tem linhas modernas e é muito bem acabado. Por fim o som, maravilhoso, A bateria que alguns reclamam eu considero boa pela potencia do equipamento. Sabendo usar os recursos, de luminosidade, internet desligada quando não necessário como tambem bluetooth, ela dura seguramente de 9 a 10horas. Melhor que ele, dentro da faixa de preço dos 300 US$ só o M21, que tambem adquiri recentemente. Não se pode esquecer que para poder ter toda a experiência com o som é nescessário um bom fone de ouvido. Eu adquir um HEADPHONE KUBA DISC2 PRO, excelente . Resumindo, vale a pena comprar o FIIO JM21.

Sieht aus wie ein Smartphone, bedient sich eigentlich wie ein Smartphone, nur telefonieren geht nicht. Wozu dann also so einen DAP aus dem Bereich Einstieg, reicht da nicht auch das Smartphone ? Kommt darauf an ob man rein auf Bluetooth Kopfhörer setzt, eher streamt statt lokale Musikdateien und einiges mehr. Meine Gründe für den Kauf waren diese: Intergrierter HiRes tauglicher Verstärker mit 4,4mm symmetrischem Ausgang micro SD Slot bis 2Tb Android 13 mit Anpassungen für HiRes Audio Handliches Format und leicht. Geplante Nutzung ist für unterwegs, nicht für zu Hause. Schaut man sich an was es für DAP's zu kaufen gibt, gibt der Markt einiges her, man kann schnell sehr viel Geld in die Hand nehmen für einen Premium DAP. Die Frage ist nur ob man "Premium" als Normalbürger hören kann. Ich glaub das nicht wirklich, aber das ist rein subjektiv. Doch nun zum FIIO JM21, die ersten Schritte und dann die spannende Frage wie klingt das Ding. Geladen wird mit Standard USB-C, es wird kein Netzteil mitgeliefert, ich verwende ein vorhandenes Standard Ladegerät mit 2A. Der mit 2400 mAh dimensionierte Akku ist relativ schnell geladen, es ist empfehlenswert den Akku ein paarmal bis auf <10% Akku zu entladen, dann entfaltet sich erst die volle Kapazität. Mit dem WLAN verbinden und schon wurde mir das Upgrade der Firmware auf Version 1.06 angeboten. Man kann sich mit seinem Google Konto im Playstore anmelden, damit stehen dann sehr viele Apps zur Verfügung. An dieser Stelle eine kleine Warnung: Es handelt sich um einen Audio Player, man sollte vermeiden sich den Player mit unzähligen Apps vollzumüllen, stattdessen nur das laden was man wirklich benötigt. In meinem Fall habe ich mir die App Musicolet geladen, sagt mir eher zu wie die mitgelieferte FIIO App. Der interne Speicher ist mit 32Gb nicht wirklich groß bemessen, doch ausreichend um dort ein paar Lieder abzulegen und dann zu hören wie klingt der DAP denn. Als Speicherweiterung habe ich mich nur für 512Gb entschieden, obwohl 2Tb möglich sind. Doch eine mit 2Tb an Musik gefüllter Speicherkarte ist die Unübersichtlichkeit der Medienbiliothek, auch Playlisten helfen da nicht viel weiter Also zunächst ein paar Musiktitel, anhand derer ich den Klang prüfe, in den Speicher geladen. den IEM Hidizs MP145 am 4,4mm Ausgang angeschlossen und ein paar der Titel angespielt. Zum Vergleich die selben Titel auf meinem iPhone + DAC angespielt. Ganz ehrlich, einen Unterschied höre ich da nicht. Wieder die Frage nach dem "Warum ?" Am iPhone habe ich Kabelsalat, der DAC hängt mit seinem kurzen USC-C Kabel am USB-C Port des iPhones. Zu Hause kein Problem, unterwegs ist das unhandlich. Ausserdem ist Speicherplatz beim iPhone nicht erweiterbar, auch bei diversen Androiden fällt der Steckplatz für SD Speicher immer mehr weg. Ein anderer Grund ist die einfache Option HiRes Audio zu hören, durch das speziell angepasste Android auf dem FIIO findet kein Downsampling statt, in der Kopfzeile des DAP wird 44, 48, 96 oder 192kHz angezeigt. Wie bekommt man nun seine Musikstücke vom PC auf den Player ? Option #1 - via USB-C Kabel, optimalerweise an einem PC mit schnellen USB Ports Option #2 - via WLAN mit eine entsprechenden App z.B. der kostenlose Totalcommander mit WIFI Pluglin Option #3 für die Speicherkarte - ein schneller USB Reader. Für den internen Speicher nutze ich Option #1 mit dem Kabel, für die SD Karte dann doch lieber den USB Reader. Habe die Speicherkarte bisher mit rund 100Gb an Musikdateien gefüllt, sind ca. 3.500 Dateien. Dann der spannende Moment, wie schnell baut sich die Musikbiliothek auf. Habe die Zeit nicht wissenschaftlich gestoppt, es waren so in etwa 2min, fügt man später noch weitere Titel hinzu, geht die Aktualisierung viel schneller, passt soweit. Wie bedient sich der Player ? Einerseits auf die übliche Art via Bildschirm, der Snapdragon 680 hat genug Power für die absolut flüssige Bedienung. Dann gibt es noch die Hardwaretasten, auf der linken Seite der Ein/Aus und laut/leise, auf der rechten Seite Play/Stop und Titel vorwärts/rückwärts. Neben den kabelgebundenen IEM's habe ich auch Bluetooth Kopfhörer ausprobiert. Apple Airpods - man kann damit Musik hören, doch die verwende ich dann doch eher mit dem Smartphone Bose QuietComfort 45 - geht deutlich besser als mit den Airpods, doch nur AAC Codec Sony WH-1000XM1 - LDAC Codec - klanglich ähnlich wie die Bose Habe lediglich Bluetooth probiert, praktisch nutzen werde ich das eher nicht. Auch meinen kabelgebunden Beyerdynamic T5 werde ich eher selten mit dem DAP nutzen, ist kein Kopfhörer für unterwegs. Im Vorfeld hatte ich mir u.a. die DAP's von Hiby R4/R6 und den iBasso DX 180 angeschaut, dann doch den eher preiswerten FIIO JM21 erworben. Solide Technik, wobei der Dual Cirrus Logic CS43198 DAC nicht in der Oberliga spielt, aber ganz ehrlich - irgendwo muss man Preis/Leistung abwägen. Im Bereich HiFi kann man sehr viel Geld für minimal besseren Klang ausgeben
