    Pros - Amazing detail, separation and articulation
    Cons - Bit pricey (especially with poly), polys still needs some fine-tuning
    Chord Mojo & Poly Review
    So I admit that this is a little. Later than I had originally planned to have this review out, life getting in the way and all that, but finally here it is, my review of the Chord Mojo & Poly.


    I purchased these myself as a pack that also includes a case (more on that later), I was hoping that gofigure (the poly configuration app) would be out by the time it came to publishing this review, but as I understand it’s still stuck in approval limbo, so I’ll have to update this review after it is released, though for the most part it doesn’t affect my opinion of the Mojo-Poly combo.

    Chord Mojo

    The Mojo comes packed in a fairly small box, the box has a picture of the Mojo on it as well as the usual specifications, overall while full gloss colour its nothing too over the top.


    Inside the box you will find the Mojo held securely in place with some foam packaging and a very short USB cable……and that’s it, now I like minimalism as much as the next person but I do feel a manual could have been included, still I guess everyone has the internet and it’s hardly a difficult product to use.


    Onto the Mojo itself, its design, like 90% of dac/amps is a rectangle, though in this case it is a rounded rectangle and the volume and power controls are significantly different from anything else not made by chord, but more on that in a sec.

    So on the top of the device you get three buttons, the leftmost button is the power switch and shows the source quality being played via a colour coding, next you have the volume up in the middle and volume down on the right, again using a spectrum of colours to show what the volume currently is. Adjustment of the volume is very easy, the increments are quite small so you can fine tune it for sensitive IEM’s, you can also hold both buttons in on power up to set the device to line out volume.

    On one end of the device you have two 3.5mm headphone jacks, not sure why they decided to put two in but I guess you can share with a friend if your phones have similar sensitivity/impedance. On the other end there is a USB in, USB charging port, optical in, and coaxial in. Under the USB charging port there is a LED which shows the battery status, again using a colour code. The Mojo also has four rubber feet that keeps it in place on your desk.


    The first thing that stood out compared to other DACs/AMPs/DAPs when listening to the Mojo was the superior separation and its presentation of micro-detail. The sound produced is incredibly articulate, its very easy to pick out the individual instruments and vocals in a track, the definition and detail is simply amazing.

    In addition to the detail I was stuck by the crispness presented, the sound of cymbals is near perfect, they sit above the music, completely un-muffled and clear. This is potentially the Mojo’s strongest trait. Now I’ve harped on about detail so I should clarify, I wouldn’t describe the sound as analytical, the amplification section has a slightly warm feel to it, making the Mojo sound alive, not at all sterile.

    While the Mojo is incredibly detailed, it thankfully isn’t too harsh on lower-quality sources. So stuff like Youtube still sounds quite good with the Mojo bringing out the best in it without ripping it to shreds. That said, there is a limit where bad is bad.


    My predominate listening to the Mojo has been with the Chord Poly as a source and my Campfire Audio Jupiter’s, which have a fairly laid-back sound, but offer incredible detail. I have also done a bit of listening with my Sennheiser HD650’s and more recently Campfire Audio Cascade’s (impressions with these will have to wait for later).


    I was not initially impressed with the pairing of the Mojo and the HD650’s but on further listing I’ve found the articulate crispness starting to come through. I can also hear much greater separation than I normally hear with Modi 2 – Vali 2 stack. The micro detail I heard on my Jupiters is there, but not nearly as obvious, the 650’s are simply not as resolving.

    The soundstage on the Modi/Vali feels, if not better, more realistic than the Mojo, but the Mojos is preferable to the Opus #1′ so it might just be the Vali’s tube injecting a little more life into the music. I did however find the bass on the Mojo to be tighter and cleaner than either of the other two.

    On the whole I really can’t fault the Mojo, there might be some features I’d like it to have and it could probably be slightly cheaper, but it’s really at the pinnacle of truly portable audio, I give it a 9/10.

    Chord Poly

    Just like its partner in crime the Poly comes in a reasonably sized gloss box. Inside the box you will find Poly packed in the same sort of foam as Mojo, however unlike Mojo Poly comes with an instruction manual (and rightly so, as its certainly less straightforward) as well as a configuration pin, a slightly longer yet thinner USB cable and, a Roon voucher for a two-month free trial.


    The Poly has the same rounded aluminium shape as the Mojo, but has no buttons save for a configuration pin hole and also has a plastic corner to allow for greater wireless reception.

    On one end Poly has two male USB connectors and a couple of plastic pins to connect it to the Mojo, on the other end you get a USB charging port (this also charges the Mojo while its connected to Poly), a micro SD card slot, the small configuration pin hole, and a light-pipe and LED that shows the batter status of the Poly and Mojo (the Poly’s LED also shows its connection status, flashing if there’s no wireless connection).


    The Poly feels fairly solidly attached to the Mojo, but it doesn’t take much force to connect or disconnect, so if your planning to use them together on the move then you will probably need a case (which my pack came with, but more on that later). To use Poly all you need to do is power on your Mojo and the Poly will automatically power on shortly afterwards.

    To set up the Poly you use a pin to push the configuration button on the end and then connect to its network, doing so opens up a web page where you can enter network details that Poly will then automatically connect to in the future. In this set up screen there are also some other options including setting your Poly to Roon mode. In future all of this will be replaced by the Gofigure App, the greatest benefit to this being the ability to easily swap between normal and Roon mode as well as being able to add networks on the fly, which currently is inconvenient to say the least.

    Now to actually use the Poly you need a smartphone (or computer, but I think that defeats the purpose a little) and for Poly and your control device to be on the same network (I haven’t filled with it too much but there is also the possibility to stream to the Poly via Bluetooth as I understand it). Now there are a few options when it comes to playing music usingt he Poly, you can use it as a Roon endpoint, you can stream music from your device to it (I use an iPhone and as such stream to it via airplay, it currently does not have chrome cast support but hopefully will in the future), or you can access music on the internal SD card and either play this music on another device (the Poly acts as a DLNA server) or set Poly as the output and play directly through the Mojo. This last method is why I bought this combo as I thought this was a great idea, the ability to store and play music on a portable dac/amp but control it from my phone really appealed to me.

    On usability I find for the most part its very reliable, I control Poly using Glider (there a few apps available that will control Poly, but this was the best one I found) which is fairly seamless and easy, but occasionally I simply run into an odd bug somewhere (Poly, Glider, the network? no real way to know) but even then it only means your playing of music takes 30 seconds longer than one would like, not massive in the scheme of things but slightly annoying.

    I find the Mojo-Poly combo manages its 9ish hours of battery life quite comfortably, the bigger issue being the drain of power on my phone from being in hotspot mode (I should add, if your willing to sacrifice the ability to use the net, you can connect to the poly’s network instead which is probably a little kinder on your phones battery)

    A further point on usability, a case to hold them really is essential to use them on the move. The one that was included as part of the combo is very nice, it’s made of a rubberised plastic of some sort, nice and solid and but nice to touch, and is lined with a kind of fabric to keep Mojo & Poly pristine. Chord also makes a leather one which looks really nice but has a price tag to match.


    The Poly is an interesting device, it has more features than I’ll ever use and this is probably my main criticism. I feel a more focused and potentially cheaper device might have been a better choice, and I can’t help but worry about the reliance on 3rd party apps. That said it is a really impressive device and for me personally it does exactly what I want, its a bit useless to score it on its own so I give the Mojo-Poly combo 8.5/10.

    Pros - musicality, size, battery life, build
    Cons - micro B connector is too fragile for pocket use
    Chord Mojo is hands down, the most fun portable dac to listen to under $1000.  It plays all genres equally well, and turns all my music from my phone into a sound I can feel engaged to hours on end. I cannot recommend this product enough! it pairs very well with my Venture Electronics Zen2.0 earbuds and Runabout 2.0 amp. This combo is a game ender for me for quite some time!

    A very accurate DAC/Headphone Amplifier
    Written by tetsuomastermai
    Published Jan 23, 2016
    Pros - Compact size, Good Dac capabilty.
    Cons - Poor bundle, not punchy bass, Doesn't charge when using.
    First of all I would like to thanks Chord to have lend me the Mojo for a few weeks, and especialy their Belgium's interlocutor Bertrand :) 
    I'm not an experimented audiophile, so my review will be brief.
    I'll not describe the Mojo once again, since all the reviewers before me have done very well (thanks to all of them). 
    I will just notice once again that the bundle is very poor: Just a short USB cable. No Iphone cable nor mini jack, to resume : pitiful.
    The aim 
    The Mojo is a very versatil small DAC/Amp to use on the go. Due to all his connectivity you can use it with a laptop, a smartphone, or even a DAP.
    His small size allows you to easily put it in your pocket with your smartphone. 
    I try some Dac/amp with my Iphone, finally I think the Mojo is one of the most convenient (as the Oppo HA-2 who which is a good one too). 
    With the Mojo you have a powerfull tool for listening streaming music through a smartphone.
    The sound
    The Dac part is very accurate, very natural, without any coloration.
    Another positive point is the soundwise, greatly open for a mobile joy like the Mojo :wink: 
    I was just disappointed with the bass, it is not as punchy as ohter Dac/amp. 
    It sounds like if there were no subbass.
    USB Charge 
    First time I used the Mojo on my laptop through USB port, I was suprised that it turns off :xf_eek: 
    Actually, there are two micro USB ports : An input one and a charging one.
    So if you want to charge the Mojo while listening music you have to plug a second USB cable in the charging port.
    The Mojo user manual doesn't recommend to charge while listening because the Mojo may warm a bit.
    That's why I found the Mojo less convenient than other models.
    Despite some small inconveniences, the Mojo is a very small and powerfull Dac/amp with an accurate and natural sound. 
    To use with a smartphone for streaming HI-Rez it is currently one of the best.
    1. Ra97oR
      It charges just fine when you are using it, I have ran my Mojo overnight on Hi-Res music while charging and it did just fine, no overheating, nothing. Nor charging the Mojo while listening induces any noise.

      Not a real issue.
      Ra97oR, Jan 23, 2016
    2. salla45
      Sorry, but IMO it doesn't seem like you've really got to grips what this beauty can do for your soul. Where's the passion? The mojo literally has me dancing for joy when I listen. More often than not I'm moved to tears. It's more like you're reviewing a dishwasher or a hairdrier. Nice 1.
      salla45, Jan 23, 2016
    3. tetsuomastermai
      @Ra97oR: My Mojo was already overheating just used and not in charging.
      And plug an usb input and an usb charging at the same time for one device is an inconvenient for me for a nomad use.
      @salla45: You got it, it was not a dream for me...
      Despite that, it has gave a good result for an electronic can :wink:

    Mojo is a very good at what it is intended to be used as – a portable DAC/amp
    Written by Ithilstone
    Published Nov 26, 2015
    Pros - - Small size and really well made product with very good finish. - Does everything as advertise and does it flawlessly. - Sound quality!
    Cons - Can become realy hot when in use during charging - Line level mode - Awkward volume control
    There is always the first time they say. I would like to thank Levi aka Musicday for this opportunity and without further ado:
    Chord Mojo arrived in small box, but true surprise came after unpacking. My first thought was “Wow it is really small” then second, after I picked it up: “uhu but that bugger is heavy”.
    No, of course it is not but unit's weight cannot be anticipated by its looks.
    Mojo is “wearing full metal jacket”  and coming straight out of box felt really cold, as it turned out that changed very quickly – but more about it after brief introduction of my ”testing rig”  and “methodology”.
    PC > optical > Foobar > WASAPI (Event) > NuForce HDP > NVA AP20 >
    - Hifiman HE-6
    - Beyerdynamic DT 990 PRO 250 ohm
    - Superlux HD681 EVO (second gen. with velour pads)
    Moto G (1st Gen) > USB OTG > Fiio E7 (non K) >
    - Audio-Technica ATH-CKX9IS
    - Koss PortaPRO
    Tracks used for testing are my trusted*:
    The Head-Fi/HDtracks Open Your Ears –  96kHz/24bit version
    HDtracks 2014 Sampler
    and HDtracks 2015 Sampler
    About Chord Mojo:
    I’m not going to list the whole spec here. It is available from Chords’s web site and other places online. My subjective impressions and the DAC's major features include...
    -          Mojo Plays all files from 32kHz to 768kHz up to 32bit
    -          Native DSD up to quad 256
    -          Li-Po battery lasts up to 10h
    Setting things up:
    Mojo + Moto G – everything just works, connect one with another using OTG USB cable and you ready to roll. Perfect couple. (btw for some reason Mojo as well as Fiio E7 are not detected by Moto G 3rd Gen while NuForce HDP works well with both phones)
    Mojo + PC
    Also very simple just download driver, install, reboot, connect Mojo with usb or coaxial cable and job done. In Foobar you need to set output, preferably to “DSD: ASIO: Chord” – it will play all supported files or you can set it as “WASAPI (event): Chord” but that setting will not let you play DSD natively and you will be limited to PCM output mode.
    Let’s begin with Mojo as a portable DAC/amp
    My first source was Moto G with Poweramp player app. I Started with Audio-Technica ATH-CKX9IS my trusted go to portables. First track I played a jazz version of Pink Floyd “Money” by Sam Yahel, Mike Moreno, Ari Hoenig, Seamus Blake from “Open Your Ears” album and first surprise, I always thought that bass is a bit muffed on those headphones but with Mojo bass was clearer and more punchy and somehow more pleasing and less coloured – and it is not very bassy track. So quick swap to Fiio E7 and I was welcomed by familiar slightly muffed warmer bass. Couple of next tracks only confirmed that Mojo is in completely different league. It should be expected, after all Mojo is around 6 times more expensive than E7 when new plus has 5 years of technological advance, nevertheless the way Mojo transformed my humble  Audio-Technica came as a huge surprise.

    Those days there is one app I use a lot  on the go: is Radio Paradise App – it allows you to listen to radio - streaming in AAC 320 – I took Mojo for a walk and spent a very pleasant hour – Mojo did an excellent job with all those lossy tracks. I also took with me Koss PortaPro unfortunately day was a bit windy and  PortaPros don’t offer much of a isolation I only listen to one or two tracks – so not much to report here.
    I was really impressed with how my Audio-Technica changed plugged to Mojo that I really didn't want to go back home.

    Next test – Mojo vs NuForce HDP
    NuForce is a desktop DAC/amp and even if equipped with a third party battery is not really portable therefore I swapped the source and plugged both DACs to PC using USB. I also picked up Beyerdynamic DT 990. DT 990’s were my go to headphones for a long time even when I owed Stax SR-404 – A bit too far on a bright side but overall very good headphones. Couple of tracks into testing session and I liked them even more on Mojo. More spacious sound stage, a notch punchier but less harsh tremble. Bass on level with NuForce maybe a bit more precise. Two tracks stranded out both completely different but effect similar “Allegro from Symphony No. 6 in G minor” and “Fireopal (Acoustic Version)” Mojo just simply takes you there.
    After DT990 time came for another cheapos – this time a bit of underdog Superlux HD681 EVO
    Again Mojo transformed those headphones– it somewhat took all what’s good about them but didn't put any emphasis on their shortcomings. Superlux are fun sounding headphones even more fun with Mojo with addition of healthy dose of clarity. That pair really shine on all those bass filled tracks.
    Last test took me the longest time and with a surprising outcome.
    I left universe of dynamic and entered the plane of plenars. Where to me there is only one King and his name is Hifiman HE-6
    Both Nuforce and Mojo has no chance to drive those monsters so I could only compare their DAC sections.
    Both DACs were plugged via USB and connected  to my Amp of choice NVA AP20**. 
    I listened to all test tracks front to back, swapping DACs and something started to occur to me. Mojo with transparent amp and very precise, fast and reviling HE-6’s was just too much, There was too much micro details, everything sounded just a notch too sharp for my liking – yes sound stage was wider and deeper and you could pinpoint everything in that space but things started to be too separated, instruments didn’t blend in as intended, things become a bit dry, voices lost a touch of realism.
    I added many more tracks to compression – from Infected Mushroom – “The Messenger 2012” and Iron Maiden – “The Number Of The Beast” to Dave Matthews – “Stay Or Leave” and Dead Can Dance – “The Host Of Seraphim”. From Red Book to Hi-Res and vinyl rips, all  with same outcome.
    Another thing to mention is that Mojo and HE-6s were truly ruthless with bad recordings – no fun to listen to at all – I found that I started to lose the joy of listening to music – instead I started to focus too much on distractions.
    Above description sound much worst that the reality – all of it took me 3 days to put into words – Mojo has a really exceptional DAC section It just doesn't work well with HE-6s unless you like details in your face and sound stage neatly separated with scalpel.
    Short conclusion:
    Let’s kick off with “giant killer” statement – Simple answer is: I don’t know! Never owned any giant DAC or a headphone amp. All of my gear is rather small.
    I believe that Mojo is a very good at what it is intended to be used as – a portable DAC/amp – works very well with small and big dynamic headphones, also helps cheaper headphones punch above their weight. Even though is clearly made to shine with Hi-Res or Ultra Hi-Res – does really good job with lossy recordings.
    A bit pricy but it is Chord after all. 
    What's good:
    - Small size and really well made product with very good finish.
    - Does everything as advertise and does it flawlessly.
    - Sound quality! 

    Noted Flaws:
    - It is scary how warm/hot Mojo becomes when in use during charging – test unit arrived completely drained and I almost dropped it when I picked it up after initial 15 minutes of use while charging it.
    It should be mentioned that Chord recommend charging with Mojo switched off. For safety Mojo has inbuilt thermal cut-out (sic!)
    - From manual “for line level mode (3V) press both volume buttons together when switching on the unit”. Mojo will not remember that setting after power down but will remember other settings like volume level. In my book it just renders Mojo useless in stationary rig. Chord clearly don’t want to cannibalise its Hugo and Hugo TT – I don’t see any other reason for 2 headphone outputs instead of replacing one with dedicated line out.
    - Volume control – there is something very unnatural and awkward about those two volume balls.
    I understand that some people actually do like it but I am not one of them
    I am strong believer in A/B testing therefore all comparison was made with gear at hand –  no references or comparing  to any other gear I have owned or listened to for longer periods. I know it is non - standard practice but I also know how biased (flawed) memory can be – especially mine.
    *- I am using those tracks for couple of reason: firstly “Samplers” are very good quality and allow to test across many types of music plus can be download for free. “Open Your Ears” is very reasonably priced and was put together as a testing album. I know them quite well and used often to compare gear. There is also one more thing – I don’t particularly like any of those songs so there is no emotional attachment – which I found helps a lot if I want to stay as objective as possible.  
    **- I listened to a number of amps with HE-6s, dedicated as well as vintage and new speaker amps and even though some were better in one way or the other, overall NVA always came on top. (with Dillan’s “dill3000” monster amp coming close but there is a huge price difference)

    2. Zardphil
      Thank you! It is said that the sound quality of Mojo is the same as Hugo's and Hugo is assumed to be at the same level as Benchmark DAC I. So I expected the Mojo have the better sound quality than HDP. Well, it seems I was expecting too much of it. Thanks a lot! 
      Zardphil, Jan 23, 2016
    3. Ithilstone
      Now - Mojo is better DAC and better HP amp - and is portable and supports more type of files natively - it is just in my opinion not a giant killer - and if you paring it with neutral amp and HP like HE-6 you may get more that you wished for.
      To me -  if I would look for a portable DAC/Amp and was willing to pay premium price - Mojo would be definitely very high (possibly even in first place) on my choice list. 
      As a desktop amp if you already have NuForce HDP I would rather save money for something truly extraordinary or buy another set of cans ;]
      Or try something different - like something vintage based on Phillips TDA 1541A - mother of all DACs ;] 
      Ithilstone, Jan 23, 2016
    4. Zardphil
      I appreciate your detailed reply and useful suggestion!! Helped me a lot! I'd better save money for a better desktop dac&amp.

    The Majestic One - Chord Mojo DAC/AMP
    Written by Dobrescu George
    Published Apr 22, 2019
    Pros - + Full Metallic Build Quality
    + Good ergonomics, nice aesthetics
    + Lots of inputs and two headphone outputs for headphones
    + Excellent battery life
    + Clear, clean, smooth, fun sound
    + Good musical note weight and good dynamics
    + Natural overall sound
    + Good price / performance ratio for a device that is used in lots of recording studios as well as by music listeners
    Cons - - Gets hot while charging
    - Charges quite slow
    - Portability is a bit of a question mark, it is very thick but short, you have to get creative if you're using it portably
    - Doesn't come with all the cables required to make it work, or with anything really
    - Smooth treble may not be for those looking for a bit more sparkle

    The Majestic One - Chord Mojo DAC/AMP


    Chord Mojo is an interesting little DAC/AMP, as it relies on a rather different DAC technology than most, relying on a FPGA, or Full Programmable Gate Array, rather than a normal DAC, paired with a pretty clean power stage, to deliver what Chord calls "the world's most advanced portable DAC/ Headphone Amplifier". We'll be putting to test and see whether Chord's statement holds true in today's review of Mojo.


    Chord is a large company from UK, who is known for having created and designed some of the world's best DAC/AMPs, like the original Hugo, which left me quite impressed at the beginning of my audiophile journey, as well as the Hugo 2 they created now, and countless others. Chord is known for good warranty and customer support, as well as interesting sales going now and then. Locally, Chord is known to be a true workhorse, and people are using their products as reference, but more about that in the "Portable Usage" part of this review.

    It should be noted that I have absolutely no affiliation with Chord, I am not receiving any incentive for this review or to sweeten things out. This review is not sponsored nor has been paid for by Chord or anyone else. I'd like to thank Chord for providing the sample for the review. The sample was provided along with Chord's request for an honest and unbiased review. This review reflects my personal experience with Chord Mojo. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in Chord Mojo find their next music companion.

    About me



    As I poited in my Youtube Video, Chord Mojo has one of the most basic packages out there, the stuff you get in the box being a really short USB cable. That's all.

    For a 500 USD DAC/AMP, this is lower than competition offers, but, most people may be interested in upgraded cables either way.

    What to look in when purchasing a high-end DAC/AMP

    1x 1amp Micro USB Charging Port Input

    2x 3.5mm Headphone Jacks

    Technical Specs:
    Output Power @ 1kHz – 600Ω 35mW
    Output Power @ 1kHz – 8Ω 720mW

    Dimensions: 82mm (l) x 60mm (w) x 22mm (h)

    Build Quality/Aesthetics/UI/Firmware

    The build quality of Chord Mojo is as solid as it gets, quite literally, this is one fully metallic device that looks like it will survive a 100 Meter drop, if you ever wanted to treat it to one. The aesthetics are on the cool and avant-garde side of things, with colored marble buttons. If you've ever had Chord Hugo before, you may think that the buttons of Mojo rotate, and they do, but to use the buttons, you need to press them.


    There are two color strength options for the buttons, and the buttons colors indicate what level you are in with Mojo. The operation is quite basic actually, despite how difficult it may seem at first to operate Mojo.

    To open it up, press the power button for a few seconds. The volume buttons are marked with Plus and Minus, and the colors go from a variety of rainbow colors, depending on the volume and level you are in. To make the buttons dimmer, just press both the volume buttons at once.


    To charge Mojo use the charging port, and to use it as a USB DAC, use the USB data port. Mojo also has Optical and Coax inputs, if you wish to use those, I actually have found myself using Optical most of times because it was more convenient to me, but the USB data port works just as well for using Mojo as a DAC/AMP.

    Mojo connects to pretty much any smartphone, as long as it is Android and more recent, at least it did with all that I threw at it. For windows, you need a USB DAC Driver.


    Other things to keep in mind are that Mojo gets quite hot while it is charging, it can't use the same port for data and charging, so you will need two cables, if you'll have it stationed at your computer as a desktop DAC/AMP, it is backed by a one-year warranty from Chord, but if using it as a desktop DAC/AMP you may be churning its battery and its battery life quite fast, and it may not live very long.

    Mojo has two headphone ports, both in a 3.5mm single ended mode, and both work very well, are created equal and can be used at the same time, in case you wanted to share your sweet music with a loved person.

    Mojo has tiny rubber feed, but those may not be enough for strapping it to a smartphone, in case you wanted to take it with you, and a rubber band separator is recommended.

    The battery life of Mojo is decent to very good, and in normal usage I haven't managed to run out of battery in a normal day of usage, as it lasts for around 8 hours in my typical usage, which is in purple-ish mode in both balls, which is the maximum volume I can use with Mojo and any headphone, without running into distortions. This color, as far as it is explained in most sources, represents a voltage of 2 Volts, anything above simply enters clipping. Charging time is about 4 hours, which is considerably longer than most competitors, which have implemented Type-C USB interfaces and quick charging by now.

    Understanding the technology and why Chord decided to not use an industry-standard DAC, and instead developed their own is not necessary to use Mojo, or enjoy it as a DAC/AMP, and I think, would give more expectations bias than necessary to listen to it. I personally did not read the technical papers on why and how it was designed, because I wanted to provide feedback on its actual sound and performance more than about its theoretical design.


    The driving power of Mojo is very good, and besides QLS QA361, DX200 and X7mkii/Q5 is one of the very few DAC/AMPs that can drive HIFIMAN Sundara to pretty much their full potential. Very few DAC/AMPs are capable of giving Sundy the dynamics, punchy, impact and detail it should have, and Mojo is one of those. Furthermore, Mojo can also drive IEMs without any hiss, and Chord has provided a good price / performance ratio for its actual driving abilities.

    Studying the circuits inside reveals that Chord used a very nice overall electronic scheme for Mojo, and it should provide a clean sound, along with good performance, no cheap electronics, and pretty well-thought design.

    Overall, it is a flawless DAC/AMP, without driver issues, no hiss, good noise isolation, but it charges a bit slow, and relies on microUSB, both things which may be a touch inconvenient. The battery life is long, the operation is hassle-free, and quite frankly, it is well built as well.

    Sound Quality

    The most interesting part about such a raved product is talking about its sound, because the design and operation have been talked about in-depth, but the sound is the most interesting aspect, and the reason you'd want to invest almost 500 USD in Mojo.


    The overall sound and tonality of Mojo is quite interesting, as it is a warmer, more fun tuned than Hugo is, and Mojo feels like a more commercial version of Chord's main house sound. The detail levels are insane, and the treble is quite smooth in textures, but not overly cut out nor absent, or too smooth. The overall tonality is very natural, and musical notes have both good thickness and weight, although in all fairness, it may be a touch too smooth and too thick to be called dead neutral. Mojo feels like it has the details of an analytical DAC/AMP, without being analytical by itself, but rather being musical. It is interesting to try and describe it, but you have to imagine that a typical analytical sound extrudes details out of music, with a strong emphasis on textures and micro-detail, while Mojo has those details, but has more emphasis on a natural, thicker more smooth and musical sound, although it doesn't lose extension at either end.

    The bass is quite deep, and actually quick, despite my description of it being natural, the bass doesn't feel slow or sticky at all. In fact, this is one of the things I love the most about Mojo, that it has the speed to be quick, but also the power to deliver a healthy punch, so for EDM and Metal music, it can keep up even with aggressive music, while with Jazz the bass stays in a more natural speed. There's another thing about its bass that kind of differs from the typical DAC/AMP experience, the bass of Mojo just flows, it doesn't feel overly quick or snappy, with lightning fast decay, which is why it can stay slower for a Jazz experience, but also speed up for metal, it responds naturally to the music that is being played. For classical music, the bass provides both the authority, and the depth required, but also the texture in the bass needed for a more typical analogue experience.

    The midrange of Mojo is extremely natural and musical, it feels full and lush, without feeling too thick or boomy, simply, it feels natural. The tonality feels pretty spot-on, and with guitar solos, you can hear that juicy tone you want from a guitar, and the same can be said about male voices, which can sound deep and authoritative. Performance on stringed instruments is also very good, with nice amounts of detail and clarity, the midrange can feel snappy and quick, but once again, the decay of each musical note is on the natural side of things, rather than being set on fast, so you don't feel like music is rushing on your, but you don't feel like things are being too slow. There is a hint of vocal forwardness and the soundstage isn't expanded unnaturally, but Mojo doesn't feel congested, and the instrument separation is quite good, and in line with other 500 USD DAC/AMPs.

    If the bass and the midrange of Mojo are very natural, the treble is slightly too smooth to be called perfectly natural, instead, treble-lovers may not find what they are looking in Mojo. The articulation and detail in the treble are quite excellent, but Mojo doesn't have any hint of sibilance, and no grain either, so the texture in the treble may feel a touch too smooth. The treble has one of those experiences where you can't say you were unhappy, though, because it has all the detail you'd like, and it is one of those fatigue-free trebles that you would want to listen for longer.


    I said in my video review that the dynamics weren't quite that impressive on Mojo, but after more listening to it, I notice now that I grew a bit too used to the dynamics of a 2000 USD system, and this is why I felt a bit underwhelmed by Mojo, now that I had more time to analyse it, it is in line with other similarly priced DAC/AMPs in terms of dynamics, like iFi xDSD and such. In fact, Mojo's dynamics aren't the highlight simply because it sounds natural, it doesn't lack dynamics, rather, it doesn't place a strong emphasis on them either, it simply strives to be as natural as possible, with a touch of smoothness and warmth, that enables a really long listening session, after which you can feel about zero fatigue.

    Potable Usage

    The portable usage of Mojo is more or less average, because although it has a good battery life, it has a long charging time, and it isn't the most easy to stack with a smartphone. Something like iFi xDSD can use a short, simple OTG cable that's easy to find in most shops, while for Mojo, you either need to look for a special Type-C to microUSB, or microUSB to microUSB short cable, to connect it to a smartphone.

    Furthermore, Mojo's shape isn't the most friendly for stacking, it is short, and quite thick, which means that with most smartphones, it will cover about half of the smartphone, although this leaves enough space for the headphone cable.


    Now, the funny thing about Mojo is that a lot of people have been using it as a Desktop DAC/AMP. In fact, Mojo is the most widely used DAC/AMP for headphones, and even as a standalone DAC in music production, throughout Romania. Most music producers found that its versatility in driving both IEMs and Headphones, having a perfect phase, and the kind of smooth detail it has, being able to both reveal all details, and provide a clean sound at the same time, but without inducing fatigue, are all perfect abilities for a DAC in their setup. Indeed, I have seen a Mojo DAC/AMP on the table of almost all sound engineers / live mixing engineers / and music workers in general in Romania, and around the world, it looks like this is quite a nice reference DAC/AMP that they use for their process, and well, if they consider it both fit and perfectly fit for music production, it should also be nice for music listening as well.

    The thing is, most people seem to have taken it out of its intended usage scenario, and instead of using Mojo portably, as it was intended, it is widely used for desktop DAC/AMP setups. Even I have used almost half-half on-the-go and on desktop, simply because it has the power, depth, clarity and detail to make a nice desktop unit, but the physical thickness and overall shape, combined with the microUSB port makes it a bit less likely to be used as a portable unit.


    As far as its driving power goes, Mojo can safely drive HIFIMAN Sundara, which is pretty much the hardest to drive portable I'd use while on-the-go. It struggles a bit with HIFIMAN Arya and HE6SE, but then again, those are not what you'd normally take while on-the-go. Mojo can drive Kennerton Thror really well, as well as Audeze LCD-MX4, and it pairs beautifully with Beyerdynamic Amiron, but with IEMs it shines just as bright, being able to give an excellent sound to Beyerdynamic Xelento, Dita Fidelity, Fealy and Dita Truth, Campfire Atlas, and many more.

    What came to me as a surprise is that it was able to handle also CrossZone CZ-1, which is fairly hard to drive well.

    This eans that Mojo isn't afraid of either hard-to-drive headphones with low or with high impedance, and this indicates that both its voltage is very clean and clear, and so is its current, both headphones that need a good voltage and which have a high impedance sound good, and the same can be said about IEMs and headphones with really low impedance that hunger for large amounts of current.

    All in all, the portable usage of Mojo is mixed with the desktop usage, but it is a very versatile and capable DAC/AMP, and the fact that it can be used equally well in both modes, and that it can drive pretty much all of the normal headphone under 1000 USD, and even headphones and IEMs that are true flagships or Summit-Fi makes Mojo a truly versatile product.


    Chord Mojo has to stand well against three main competitors to be worth its asking price, and being a portable product, all of those are portable DAC/AMPs. The 3 products it has to stand well against are iFi xDSD (400 USD), FiiO Q5 + AM05 (450 USD), and iFi iDSD Micro Black Label (500 USD). There are other interesting DAC/AMPs out there, but almost all questions and inquiries about Mojo were about comparisons with those three, and so I'll be focusing on those.


    ChordMojo vs FiiO Q5 (AM05) - Things start to get funny as soon as you start comparing Mojo to other devices, because, besides the sonic quality, how practical a device is, comes into play. Q5 + AM05 from FiiO is pretty much the versatility master of DAC/AMPs, it is pretty much the most versatile one, it has both the power and the abilities to be named as such, it has Line Out, Bluetooth, multiple AMP modules, and it has the shape that makes it perfect to stack to a smartphone. Furthermore, Q5 also comes with all the cables required to connect it to pretty much anything, making it a better package as well. Where things start to get interesting is at the sound level, because Mojo has a different sound, Q5 with AM05, which is the best configuration for Q5 will be wider, considerably more neutral, and have similar note decay to Mojo, but at the detail and micro detail level, Mojo reveals more details and micro details than Q5. Mojo is also more dynamic and deeper, but I'd say that Q5 is a touch more crisp in the treble, where Q5 is smoother and more fatigue-free.

    Chord Mojo vs iFi xDSD - iFi xDSD may take a few trophies home for its design and aesthetic, but when it comes to the package, it is also pretty nice, with all the cables and accessories necessary to use it included in the package. The battery life between xDSD and Mojo is quite similar if we're being honest, and so is the overall usage scenario, but xDSD has some tweaks, like the X-Bass and the 3D Soundstage tweaks that you can simply flick on or off with a button. When it comes to the overall sound, Mojo feels more detailed, more smooth, has a way smoother treble, but still with a natural amount of energy, xDSD feels a touch wider, while Mojo feels deeper and more layered, Mojo feels like it can expose certain details better, while xDSD feels like it has a slightly more versatile approach. The driving power is better on Mojo, and it can drive quite a few more headphones, louder, with better control, and can drive Sundara, for example, to its full potential, better than xDSD, although both Mojo and xDSD are pretty much dead silent with IEMs and low impedance headphones. It is probable, though, that users who invest so much in xDSD won't use the Bluetooth function on xDSD quite that much, so at the end of the day, the two features that xDSD has, and are quite important, are the 3D soundstage, and the X-Bass enhancements, and this is because sometimes just turning those on will make the EQ process of a headphone simpler. On the other hand, although for Treble, you may feel like Mojo is a touch smooth, for bass, its overall performance is smoother and yet more detailed, has more authority and is more powerful than xDSD, simply put, Mojo naturally drives headphones better (when talking about hard to drive headphones especially). Both xDSD and Mojo can be used as a full time desktop DAC, but only Mojo has 2 Headphone outputs. xDSD has a Balanced outputs, although the sound is very similar to its single ended output if you use it (they have a unique approach to balanced outputs). xDSD can decode MQA, while Mojo can't, but on this note, within my rather large collection of music, I have about zero albums available in MQA (including my Tidal library), so when deciding between the two, you should check whether you actually have any albums in MQA in your collection. At the end of the day, if you're looking for a more portable versatile device, that charges faster and which is a touch more versatile, then xDSD is a nice choice, but Mojo does overtake it in terms of overall technical detail, smoothness, and depth, and also in terms of driving power and control.

    Chord Mojo vs iFi iDSD BL Micro - iDSD BL Micro is actually the one device on this list that's actually less portable than Mojo, and by a rather good margin, because it is both heavier, and it is also larger physically, although, it does have more raw driving power than Mojo. The sound of iDSD BL is different from Mojo, iDSD BL has a very different approach to music, with less emphasis on dynamics, more emphasis on depth, and with a considerably less forward and a much much more laid back presentation. This makes Mojo stand out as more dynamic, more punchy and more forward, with more detail, and judging by the fact that most people describe Mojo as slightly laid back, you should get an idea of where each of them stands. In terms of micro-details, both have good micro-details, but with the very laid back character of iDSD Micro BL, you feel like those micro-details are farther away from you, while Mojo brings them closer, and makes them slightly more articulate. The driving power of iDSD BL is considerably stronger than Mojo, but by the point you need that driving power, you're most probably standing at a desk rather than using either of them portably. Overall, iDSD Micro BL is an excellent device for audio portability, features a true line out, 3.5mm Aux input, it features one of the best DACs seen in a portable, can charge a smartphone, and can also take Coax signal input, making it really easy to recommend as a portable DAC/AMP. Mojo, on the other hand, kind of completes it, with a more forward sound, also taking in Coax input, but optical as well, having two Headphone Outputs, Optical Inputs, and also having a really nice battery life, the two DAC/AMPs, at the end of the day, feeling a bit more complementary, you're most probably in need of one or the other, but it is good to take into account that Mojo is quite a bit more convenient to take portably, while iDSD Micro BL not exactly.


    The pairing of Mojo is pretty much flawless with any Headphone and IEM unless they are exceptionally hard to drive or picky, and as such picking just 3 to write about in this review has been quite challenging, but I have selected Dita Fidelity, for its excellent resolution and clarity, for its analytical sound that will surely reveal Mojo's characteristics well, HIFIMAN Sundara, which I consider a true workhorse for portability, I actually use this quite often while on-the-go, and consider that Mojo and Sundara make a great pair (now that I had more time to listen to them), and also Audeze LCD-MX4, which is a true flagship that's beautiful to pair with pretty much anything for their enjoyable sound, and to spend more time with them. Sennheiser HD660S pairs just as nicely with Mojo, and so does Campfire Atlas and many others, but the ones above are my choices for today's review, as offering more pairings would make this a really long read.


    Chord Mojo + HIFIMAN Sundara - Sundara makes an interesting pairing with Mojo because Mojo has all the power needed to drive Sundara, but above that, Mojo adds an amazing layer of micro-details and clarity, but also a nice depth to Sundara. The dynamics are as amazing as you'd expect from a well-driven Sundara, making this pairing really easy to recommend, especially to those who wanted a Sundara that has a more full and smooth sound, rather than their usual neutral-ish presentation.

    Chord Mojo + Dita Fidelity - Dita fidelity is another example of headphone that makes a great pair with Mojo, and this is because Fidelity is one analytical IEM, and Mojo compliments their nature quite well if you wanted them to have a fuller, deeper and more smooth sound. Of course, you lose a bit of edge and sparkle when pairing Fidelity with Mojo rather than with a very neutral DAC/AMP, but you gain quite a bit in smoothness and in overall enjoyment for long hours of listening, as otherwise an analytical sound can get a bit fatiguing after a while.

    Chord Mojo + Audeze LCD-MX4 - LCD-MX4 is one of the best flagship studio monitoring / mastering headphones out there, created and designed by Audeze and made to be a statement in how good a Planar can be for monitoring, mixing and mastering. Mojo has all the power needed to drive LCD-MX4 quite well, and also pairs well with them in terms of sound, giving them a deep and precise sound, and enhancing their already smooth signature to allow you to work for many hours in a row to get that perfect mix / master you've been looking for. The details of this pairing are quite great, and so are the dynamics.

    Value and Conclusion

    Chord Mojo has been one interesting DAC/AMP to review and you can understand both its price tag, and the reason why it is so widely used, just a bit better now. The fact that it stood the test of time so well, having been released quite a while ago, without dropping in price much, and still being not only considered, but also bought by many, shows that it provides a fair performance for its price.


    The package is very basic, and I can't say I'm quite satisfied, there are 100 USD DAC/AMPs that come with more, but to be fair, besides some rubber bands, and a silicone band separator, which isn't even absolutely necessary, there's very little that you could desire for more with Mojo. It is probably a good idea to purchase high quality cables for Mojo anyways, and an OEM probably wouldn't have been quite as good as a good aftermarket cable, but still, Mojo will not win any competition for its package.

    The build quality is extremely solid, Mojo has a nice touch finish, it doesn't get scratched easily, and even after taking it out during rain, snow, storm, and sandstorm, it has zero scratches and works as new. Pretty great job from the guys at Chord. The software is also pretty much rock stable, and although it charges a bit slow, it provides good battery life, and its operation is hassle-free.


    The colored balls of Mojo are fun to use, and I don't mind a bit of color in my DAC/AMPs, and if you walk a lot late at night, they make a good flashlight, although I'm not sure they were designed as such. The volume and driving power is enough for pretty much all your typical and even for most hard to drive and special headphones, bar the 2-3 in this world that you wouldn't take outside anyways (this is keeping in mind Mojo is Chord's Portable DAC/AMP).

    Chord Mojo sounds pretty majestic, with a natural sound through and through, a great depth and weight to its music, a slightly forward yet smooth and extremely detailed midrange, and a fatigue-free treble that still bears all the detail and clarity it should have, but has zero fatigue. The soundstage is natural in size, and the dynamics are quite amazing for its price point, making Mojo a really nice overall DAC/AMP.


    At the end of the day, if you're looking for a well-built, portable DAC/AMP that you can also use for your desktop setup, which has two headphone outputs, which has USB, Optical and Coaxial input, which has a good amount of driving power and is extremely versatile, with a really natural, yet incredibly detailed sound, you should check out Chord Mojo, as it may become your next music companion, as it did even with a ton of music industry workers and other music lovers.

      @szore - If I'll have a chance to hear 1a, I'll surely let you know! At the moment I only heard 1Z, and there, I actually felt they were somewhat similar, Mojo felt more liquid, also had more punch, where 1Z was warmer in general.

    Chord Mojo : A small, affordable and highly musical portable device
    Written by slefr
    Published Dec 13, 2015
    Pros - An holographic and warm sound, excellent instrument layering with lots of details and impact
    Cons - Bass impact is good but could be stronger, provided USB cable a bit short
    This is my first  review but also my first post on head-fi. 
    A friend proposed to me to evaluate the new Chord Mojo through an evaluation tour organized by Chord. I accepted happily as I was very curious about its sound signature compared to its big brother Hugo I tested some time ago. While I really liked the Chord Hugo, I considered it too bulky and expansive as an alternative DAC and amp for my Astell and Kern AK240 and decided not to buy it.
    Build quality and operating features
    I was surprised to see how small Mojo is. It’s a bit on the heavy side with a metal enclosure rather than use of plastic but seems built to last. Volume setting is easy through large buttons which indicate volume levels with colors ranking from red to blue. 
    I won't go into further details as they have already been provided by previous reviewers better than I could do. I will just say that I like the original design of Mojo and I think it is well thought and built for portable use, it doesn't take long to understand how it works.
    Sound Quality 
    Soundwise, Mojo has been compared to the Macbook Pro analog output using Audirvana player and to the AK240 using its own DAC/AMP. Mojo was connected to the MBPro through USB. I mainly used by beloved Earsonics Velvet IEM for most of the listenings as I wanted to assess Mojo for portable use.
    The differences with MBPro analog output were striking, the latest giving a flat and boring sound in comparison with the Mojo. On Alan Parson Project/The Very Best of AP Project/Prime Time track, cymbals sounded far more detailed and realistic with Mojo opposite to the plastic and artificial rendering with MBPro output. Voices were more natural with Mojo, airier with a better soundstage and instrument separation, bass was also faster and more impactful. On Miles Davies/Kind of Blue/So What track, The piano was flat and light sounding with a lack of harmonics, sounding again plastic with MBPro output, the same was true for the trumpet and cymbals. Notes were thicker, fuller with Mojo and instruments sounded far more real with it. On Cassandra Wilson/Another Country track, Instruments were sparkly and lush with Mojo, Cassandra’s voice was more realistic with Mojo. There was a better distinction in space between voice and instruments.
    So the Chord Mojo sounded way better that MBPro output but what about the comparison with the AK240 ? On previous Cassandra Wilson/Another Country track, AK240 performed better that the MBPro output but was still behind Mojo with less depth and a warmth. On Pink Floyd/The Wall/Another Brick in the Wall 2 track, there was less impact with AK240, children voices were more detailed with Mojo, the overall representation was fuller, more convincing and pleasing with Mojo. On Dead Can Dance/Anastasis/Anabasis track, there was a better instrument separation with Mojo as well as a more laid back and warmer representation, a more 3D soundstage. Bass impact was equivalent between AK240 and Mojo. AK240 sounded a bit sterile compared to Mojo. On Gary Karr/Adagio d’Albinoni/Albinoni-Giazotto: Adagio in G minor, there was again more depth with Mojo, thicker notes and more details on bow strokes on the double bass strings.
    So my experience with Mojo was very good, it reminds me the strengths of Hugo with a detailed, impacted, warm and holographic sound. It’s small enough to be used as a portable solution with an iphone or a low end DAP used as source. I’m seriously considering replacing my AK240 with a Mojo combined with an iPhone with sufficient storage to be able to use Qobuz streaming.
    I would like to thank Chord for allowing me to assess the Mojo. I’m convinced this little gem will have a great success thanks to an adequate price with regards to its performances.

    Chord's Phenomenal Little DAC
    Written by Deftone
    Published Apr 6, 2017
    Pros - Exceptional Audio Quality, Solid Build, Musicality, Price.
    Cons - No Auto Shut Off
    Every now and then i try a product and instantly say to myself "Wow"
    Chord Mojo has impressed me from the first minute of playback and still does everyday since buying it February 2016.

    The box itself is small and compact, Mojo comes tightly packed in some foam and short micro usb cable is supplied. A simple package but i would of like to see a standard 8 inch micro to micro OTG cable with a clip on ferrite choke in the box.

    Build & Design
    The design is perfect in my opinion, solid metal black box with illuminated acrylic balls for adjusting the volume and power on/off. The power ball LED changes colour depending on the sample rate fed to Mojo, simple but effective. Build Quality is also exceptional, a really solid feeling unit.

    Power & Battery Life
    Mojo can power almost every headphone available from 8ohms to 600ohms and i no problems driving many iems and headphones with it. Two of my favourite headphones to use with mojo are Sennheiser HD650 (300ohms) and AKG K612pro (120ohms) 
    I have found that battery life is around 7-9 hours which is good enough for me personally but what i would of loved to see on this device is an auto shut off feature, maybe 10minutes after not receiving any signal from my smartphone when using OTG for music playback for example. this wont be a problem for everyone but for me who sometimes goes to sleep listening to music this would save another charge in the morning.

    Music & Listening
    98% of my music genre is metal and rock with the occasional acoustic album.

    (2) Archos 55 Diamond - Android 6 - Usb Audio Player Pro - Bitperfect mode - 16/44.1 WAV CD rips
    Beyond Creation - Omnipresent Perception (Techical Metal)
    I like to use this track for testing transients as its got a lot of layered instruments played fast. Mojo shows its exceptional speed and effortlessness, instruments are well separated without any smearing or blending.
    Horrendous - The Vermillion (Acoustic)
    A stand out instrumental piece from an otherwise chaotic and intense album, the twang and plucks from strings are rendered beautifully, a timbre and realism i have not heard in a DAC before.
    A Perfect Circle - The Package (Progressive Metal)
    This is a track i like to use for testing out LF response on a system. if there is a focus on bass this song will simply sound bass heavy and overbearing, not with mojo, the bass guitar is very tight and clean with a ton of detail and texture.
    Machine Head - Bite The Bullet (Heavy Metal)(Live)
    A live track which can show how wide and deep the soundstage can be with just headphones, with mojo im getting an impressive full 3D soundstage not just wide or deep. 

    Conclusion - Mojo is very well built, simple but effective design, musical, smooth and very detailed sound, easily the best DAC/Amp i have heard under £1,000.

    Pros - Great sound. Reveals all the little details in your music.
    Cons - Looks like a kids toy
    It would of gotten a 5 star rating, if it wasn't so expensive.
    So I got to listen to the MOJO yesterday through the JVC SZ1000.  Total different animal of an amp.  Nice clean subbass, while staying musical.  MOJO sounds like the good stereo equipment from the 70's and 80's with the JVC's plugged in. You can hear all the little details in your music.  I think it's worth 350,- , but not the current asking price.  Looks like a child's toy, but feels solid. 
    Still amazes me how well the JVC responds to EQ and on different equipment.  I've been "remastering" some of older music and been using the JVC's for that.  When I listened to the MOJO, my old music sounded like they were remastered by me.  Stereo image is a tad wider, has a bit of BBE/sonic maximer effect going on.  Mojo for the win.
    I used the MOJO as a dac only most of the time.  Didn't like the sound signature as much, which is a personal thing.  So I used line out mode and send the output through the FIIO's and Parasound equipment of mine and liked it way more.  The biggest difference in sound quality for me, is when playing my music from the Iphone through the MOJO.  Huge difference in sound quality.  Mojo for the win again.  
    Subbass is really really really clean.  Sounds like a pair of 18" EV horn loaded subwoofers.  MOJO for the win yet again.  
    Hearing all the little details in my music with the MOJO, reminds me of when I use my old Luxman C12 preamp.  The Luxman is a big dinosaur and the MOJO is the evolution of it.  So with the MOJO you get the T-Rex sound,  from a unit the size of a house lizard.  Mojo for the WIN!

    The Mojo. Get Inside Your Music.
    Written by ShreyasMax

    Pros - Brilliant Natural Sound, Detail Retrieval.
    Cons - No Volume Knob :)P), Lack of accessories & interconnects
    Intro >

    For all head-fi users and visitors, it'd be a surprise for me if they haven't come across the Mojo ever, in the last six months or so. The amount of threads and discussion on this one device has been huge.
    For the uninitiated though, the Mojo is a portable DAC/amp by Chord Electronics that takes digital audio input from your smartphone, computer or DAP (Digital Audio Player) and outputs a superior quality audio signal to two 3.5mm headphone jacks. The digital inputs are USB and Coaxial, and there's a line level output option set by jointly holding down both volume buttons when powering on the device. The technical specifications are available on many a website, including Chord's own, and I shall avoid describing them again here.  


    But do read through all the research and development involved in the custom DAC implementation based on FPGA programming done by its creators, as it’s a very interesting and informative discussion in itself. 
    Yours truly was provided with the Mojo by my good friend @raghavsomani of Headphone Zone (India) for a couple of weeks; I duly picked it up from their office in Mumbai, and spent the two weeks of my holiday at my hometown in Kerala in blissful happiness.

    So big thanks to them for giving me the opportunity to listen to this wonderful piece of gear in exchange for my honest opinion and thoughts.


    Build/ Size >


    This is a diminutive little device, all 'aircraft grade' aluminum, and is truly bulletproof, in my humble opinion. Not that I've tested it, but I certainly feel so, and invite you to take out that shotgun, and fire one into the Mojo. Okay, please don't. It still might survive unscathed though.
    WP_20160402_15_27_41_Pro_LI.jpg WP_20160405_16_01_17_Pro.jpg
    Above: The Mojo hooked to my FiiO X3 1st gen using the L16 interconnect via coaxial. Listening done mainly with Fidelio X2.


    Moving on, it fits very comfortably when held in one hand, and is a welcome departure from the usual rectangular brick shape for dacs that has become now commonplace, barring the Sony PHA series, and maybe a couple others. The 'Made in England' label is an added reassurance of the build quality. 


    The most striking feature, apart from the glowing orbs of course, is that it has all subtly rounded corners, and the matte finish adds to a surface that is very touch friendly in my opinion. I wish Chord included some sort of a case in the box, but there are a few available for purchase separately. 


    As far as looks go, it's a no-holds-barred approach that Chord have adapted, sticking to their tradition, and I personally find it attractive. YMMV though. 


    Sound >


    Now for the all important aspect, that outweighs all other features as far as I'm concerned. Put simply, it sounds, wait for it, just brilliant.  


    What makes it brilliant for me are a combination of many different aspects of the sound that when compared to other devices in its class, it just edges ahead in my opinion.  


    The Mojo has a slightly warm sound signature, meaning that the mid range frequencies and sounds get that slight preference, if one may call it that, ahead of the lower and treble frequencies. But this isn't to say the bass or treble regions are recessed by any means. On the contrary, the bass and treble sounds have class leading extension and definition, to my ears. And for me the winning feature in favor of the Mojo is, in one word, natural.  


    My continual quest for the best sound possible at the best price has begun to define itself more clearly after using the Mojo. I've realised that rather than looking for the most detailed, most resolving, and most 'fun' sounding devices or combinations, my ideal target sound is making me look for the most 'natural' and 'realistic' sounding device or setup. This is my goal. But this statement has an inherent and fundamental problem; what exactly is the natural sound of an instrument? How 'real' can one get in terms of an instrument or voice? The word 'timbre' is used to describe the tone of an instrument as heard, compared to when its played live in front (or side, depending on recording of course) of the listener. 


    Earlier when I had the FiiO X7 for review I had thought that its timbre was the most realistic I had heard up till then. Added to this its slightly enhanced treble made acoustic guitars among others sound as natural as I'd heard. But there was that slight enhancement in the treble that still retained the X7's 'digital' roots, if one may call it that. 


    Recently I purchased the iBasso D14 'Bushmaster' dac-amp, and have been running it through coaxial out of my FiiO X3 1st gen. I'm thoroughly satisfied with its sound; detailed, uncolored, fairly neutral IMO. But having the Mojo made me realize that the D14, in spite of being very detailed, clear, and uncolored, was still not as natural sounding. Though there was no flaw or lack of detail in the D14 that I could pick, it just wasn't that 'involving' as the Mojo. The D14 though, at its current price of 199$ US, is a brilliant performer by itself, and its no surprise that its preferred by many over the sound of the DX90 DAP. 
    WP_20160226_19_46_14_Pro.jpg WP_20160305_16_20_41_Pro.jpg
    The iBasso D14 'Bushmaster' is no slouch


    The Mojo, on the other hand, retails for a higher price of 600$ US, and is almost on par pricewise with the FiiO X7.  Comparing these two, I believe the Mojo has better matchability with a higher number of headphones and IEMs with varying sound signatures, whereas the X7 would suit listeners who prefer their sound to be slightly enhanced in the treble, or those looking to balance out overly warm headphones.  


    But to my preferences,  the Mojo is the winner, because every little detail seems effortlessly retrieved,  instruments and vocals sound more 'real', and it has gotten me that bit closer to, what is to my ears, that ideal sound reproduction.  


    Value/ Conclusion >


    At its price, I feel that currently it is the best value for a portable source device in terms of sound quality alone. And to get an even better sense of realism than that offered by the Mojo, I would think one's wallet would have to start getting unreal, real soon.

      @xecutor - Thanks for the compliment; appreciate it.
       I didn't do a proper battery run down test as I was continually travelling throughout the time I had the unit with me, but I can tell that it does last the stipulated 8 hours or so on continuous usage. I used to charge it out of USB on my laptop for about a couple hours every other day or two, and it never went down to zero battery; it got till red on the charging LED only once. 
      Hope this helps, cheers

    Chord Mojo Review
    Written by silvrr
    Published Mar 25, 2016
    Pros - Small, portable, great sound
    Cons - May run out of juice on power hungry headphones
    I made some changes just before I was sent the Mojo for review that really made this review into a David vs. Goliath and old vs. new matchup.  The mojo is the latest technology, fits in the palm of your hand and runs off a battery.  My Zdac and Lyr 2 setup is big, hot, sucks power from the wall and relies on older technology.  The Zdac was released in early 2013 and the Lyr relies on tubes which have been around since the beginning of the 1900s.
    I really enjoyed my short time with the Mojo and want to say thanks to Todd for putting this review tour together.    
    I was sent a Mojo in exchange for my review by Todd The Vinyl Junkie (TTVJ).  I have no connection to TTVJ or Chord other than receiving the Mojo for review.  It went on to the next reviewer after my week with it. 
    About ME / My Listening Style:
    I am not a critical listener; I don’t find enjoyment in listening to music and trying to listen for every last detail.  When I listen to music I generally am sitting in a comfy chair, or in bed, and relaxing and enjoying the music.  I appreciate detail and accurate reproduction but tend to lean towards a warmer more laid back sound.  In the past I have had a pair of DT880s which while very technically competent were just to bright and aggressive, I much prefer something like my ZMFs or the HD650. 
    Hardware & Specifications:
    Packaging is pretty simple, the Mojo comes in a two part box with a bit of foam to cushion in transport.  No frills.  The side of the inner box displays a road map of sorts to the color indications for the bit rate display.  The only accessory is a USB cable to hook the Mojo up to a source and/or power for charging. 
    You do not get a power adapter, and you will need one.  Chord recommends 1A output form a 5v source to charge the Mojo.  Many USB ports will not provide the needed power to charge the Mojo (it will charge, but take forever).   I used a iPad charger that I had as a spare.   The iPad charger puts out 2.1 amps at 5v and charged the Mojo overnight.  I put the Mojo on the charger each night and in the morning it was charged and ready to go (as indicated by the charging light not being illuminated)
    **This was a review sample, it had been passed to 5-6 other reviewers before I got it, so your results may vary.
    Technical Specifications:
    These are pulled from Chord’s site at: http://www.chordelectronics.co.uk/mojo/
    Works with Android, iPhone, Windows and Mac
    Charges in just 4 hours to provide up to 10 hours use.
    Compatible with headphones from 4Ω to 800Ω
    The case is machined from a single solid block of aluminum.
    Three digital inputs - USB, Coaxial, and Optical
    Plays all files from 32kHz to 768kHz and even DSD 256
    Output Power @ 1kHz (600 ohms 35mW) (8 ohms 720mW)
    Output Impedance: 0.075 ohms
    Dynamic Range: 125dB
    THD @ 3v - 0.00017%: 
    A few specifications I didn't find on Chords site:
    For Americans: 3.23” W, 2.44”D, 0.85”H
    For the Rest of the World: 82.8 W, 62D, 21.5H
    The tiny feet on the bottom add a bit to the eight but its not much. There is also a picture below comparing it to my iPhone 6s.
    6.1 Ounces
    Objective Measurements:
    For a good summary of the objective measurements of the Mojo see the link below:
    Using the Mojo:
    I would recommend reading the manual while your mojo is charging for the first time.  There is some good info and its brief but provides some important details on use.  A lot of people are suggesting a 10 hour minimum first charge, not sure where it came from but seems to be going around, the manual is silent on it. 
    The Mojo’s chasis is two pieces of aluminum held together by 8 screws on the bottom.   It is a really solid piece and should last a long time. After going through the hands of a number of other reviewers and being shipped all over the country it looked like new to me, no scratches and finger prints wipe off with a t-shirt. The little orbs/balls are actually free floating in the holes and can spin around.  Not sure if anything can get behind them and cause an issue but as long as you keep your hands relatively clean I cannot see it being an issue.  All the jacks feel solid and don’t provide any wiggle or feel loose. 
    Most of the Mojo’s external features are pretty self-explanatory.  There are two headphone outs which is unique but everything else is pretty normal, except for those glowing orbs. 
    Those little orbs tell you a few details during playback, and perform there functions as noted in the picture above. 
    The power orb displays the sampling frequency being fed to the DAC by your player of choice using the colors below:
    The volume buttons also display a range of colors depending on the volume settings in use.  There appears to be three stages of the volume indication.  From zero the Mojo runs through the color field above quickly and then starts back over at red and moves to light purple.   There is a final stage where only the + volume button will change colors.  I found with my headphones I was always in the second section of volume indication and typically was in the dark blue range with my ZMF’s.  With the M6 Pros I was in the second volume section but stayed below the yellow/green range.  When just wanting some background music I was in the first section in the light purple.
    I scrolled through the user’s manual before the Mojo was sent to me and got a basic understanding.  Hold the power button for two seconds to turn on and wait for the faint click and its ready to go.  The power ball cycles through the colors as it starts up. 
    To use the Mojo as a DAC only and provide a 3V line out output you just click both volume buttons right after the Mojo powers on. 
    I found coarse volume adjustments to take too long either by clicking the ball or holding it down.   However, I found fine adjustments to work nicely by giving the ball a few clicks.  I tend to flip the volume down if I need to talk to someone rather than pause a track so a quick dial is my preference, or a mute button.
    Via USB on the Raspberry Pi it was plug and play.  RuneAudio recognized the Mojo and displayed Mojo in the list of output devices.  On all of my Windows PCs the drivers installed without issues (Windows 7 and Windows 10). 
    Optical was plug and play also, once I remembered to enable my optical out.  24/96 content played with no issues and was reported correctly by the power balls color.  24/192 gave a subtle click/pop in my left ear each time I started the song.  I don’t have another optical source to test so this may be the fault of my motherboard.      
    How does it sound?

    Music is ripped from a CD in either ALAC or FLAC at 16/44.1 unless otherwise noted.  Player and setup is noted above in each source listing.  
    I received the Mojo on Saturday and did some general listening over the weekend.  I spent a lot of time on the Mojo and found it worked nicely as a portable solution.  With one power cord (Pi power source) I can move my entire listening rig up to the bedroom or into a quiet room in the house.  The battery lasted through each session (up to 4 hours).  Initial impressions going back and forth with the Zdac/Lyr stack is the Mojo is a bit more controlled and the stack doesn’t have the same snap/control to the sound.  The tubes in the Lyr were brand new and only had ~10 or so hours run time.  They were left on over the weekend and by Monday things seemed a bit more evenly matched. 
    Steeley Dan – Aja: I went back and forth a number of times on this one trying to hear differences.  I ‘think’ I could hear a very slight difference in the drum stick click Steve Gadd makes around the 5:00 mark.  After a number of times back and forth the Mojo has a more realistic click to me, that is splitting hairs though.  Overall the two systems are pretty evenly matched using this sample.  I had to look over and see which device I was plugged into twice during this stint so that tells you how close the two setups are.
    Steely Dan – Deacon Blues: Concentrating on the saxophone after around the 4:00 mark my preference is the Zdac/Lyr stack, I think the stack is just a bit smoother and more pleasant to listen to.
    Beastie Boys – Slow Ride: Listened to the first ~25 seconds of this song over and over again on both setups.  I call this one a draw.  The Mojo is really impressing me here as I turn both setups a bit so see how bass is handled.  There is a heavy bass line after the initial percussion intro.  The Mojo holds its own even as I push the volume.
    Dire Straits – Money For Nothing: This is a quieter track overall when it comes to recording level and I like to listen to it pretty loud.   The Mojo struggled on this one; it was pushed into the light purple/white volume levels and couldn’t produce the bass the Lyr was at this volume level.  The Lyr is just really hitting its stride and sounds fantastic, switching to the Mojo and the bass suffers and overall things are sounding a bit harsh.  The Lyr is capable of putting over 5 times the wattage into the ZMFs as the Mojo, I was surprised it took this long for me to run into a test where the Mojo ran out of power compared to the Lyr, really says something about the Mojo.  
    Eagles - Hotel California (Hotel California): The Mojo is lacking in bass during the intro.  The Lyr is big and full on the bass line but the Mojo is losing the bass behind the rest of the song as the volume goes up.
    Fleetwood Mac - The Chain (Rumors): This is another song with a lower recording level.  The Mojo is getting pushed into the third volume stage if I want to turn this one up.   The Mojo and the ZMFs do not pair well as you push the Mojo, it becomes a bit shrill and the bass and mids really suffer. Turning it down the Mojo pulls ahead, I'm liking the Mids from the bass guitar better. Although very close I would say the Mojo is keeping everything separated a bit more.
    Eagles - Hotel California (HD Tracks 24/96):  I call this one a draw.  I really pulled this track up to listen to what I assume is a brush on the snare drum at a few points in the song.  It's in the lower back of the left ear on both setups. Both setups were equal to my ears in placing it and separating it from the rest of the track.  That placement that is almost behind your ear is something I first noticed with the Zdac, when I had my Modi, it was there but didn't have the same placement and desperation.
    Daft Punk - Get Lucky (256 AAC) I focused in on the claps in this song.  The have a good presentation in both width and sound on both setups, I'm calling this on a draw.
    After running into the power issue on the Mojo I remembered that you can set it to a DAC only mode and get a 3V line out.  I set this up to take the amp out of the equation and ran both the Zdac and Mojo through the Lyr.  
    I spent a lot of time switching between the two while listening to Hotel California (Hell Freezes Over) and a few tracks from Rumors by Fleetwood Mac.  I would think the Mojo was pulling more detail and the Zdac had a bit of a veil but then I would switch back and hear the same from the Zdac.  I tried both longer listening sessions and rapid switches and came to the conclusion that any differences are so small that I would never be able to blindly say this is the Mojo and this is the Zdac.  That result really goes for the whole review I did, except when the Mojo runs out of power and the differences become very evident.
    I really enjoyed the Mojo, for its size and the fact that is runs off battery it really punches above its weight.  Being able to move my entire listening rig up to the bedroom by unplugging one cord and carrying it all in one had was pretty nice.  However, I think for power hungry cans or inefficient cans I would be sure to get a demo and compare it to a desktop setup.  During my listening tests, when combined with a track with a lower recording level the Mojo would struggle.
    When I didn’t run into power issues the Mojo was wonderful sonically.  There is a lot of detail and a smoothness that I really enjoyed. I would definitely recommend it to anyone looking for a portable setup.  I held its own against a power hungry desktop setup and only rarely ran out of power and started to struggle.  
    Other Reviews:
    Other Reviews from me:
    Long Term Update (12/14/2016):
    I sold my Mojo last night and figured I would post up in my review on why I sold it.  
    The first really isn't the Mojos fault but something to think about when buying one.  I constantly ran out of battery and/or found it dead.  I would have it on and forget to turn it off and come back to find it dead.  Again, not the Mojos fault at all, however, from a dead state you have to wait for a small charge before the Mojo will fire up and let you listen.  I had it fire up a few times and then die until it had a better charge.  This is with a 2.1 amp Apple iPad charger too, so no lack of current.  This and over extended absences the Mojo will self drain and you end up with short listen times or it can be completely dead.  
    Second was the static.  I beleive this is linked to the lack of galvanic isolation on the board (which was done to save battery life).  So when next to my iPhone 6s or next to a Raspberry Pi with Wifi, (both of which I use as a source) you could get static from the EMI.  Using longer cables and getting the Mojo away from the device can help.  I would also get the same result on Optical when charging, which I assume is for the same reason.   
    I still think the Mojo is a great product, however, I didn't end up using it in a mobile application as much as I thought I would and that combined with the annoyances above let me to move on.  I think Im going to stick with a all in one product for the ease of moving around my house, however, it will be powered by mains and not a battery.

      Thanks for the feedback.  The Mojo is pretty good when you consider its size and that it runs off a battery.  During my initial listening I got the impression that the Mojo was pulling a lot of detail and had a great presentation of the music, and began to think there was something well above and beyond what my lyr/zdac was providing.  However, when switching back an forth for longer listening sessions and later quick A/B tests the two setups were revealed to be very closely matched.  I do think there are differences between the two, however, in a blind test I do not think that I could say which is which.  I wonder if "the second coming" people are comparing the Mojo to a known standard and believe that the differences are so night and day that they could pick the Mojo in a A/B comparison easily.
