  • General Information:

    A contraction of ‘Mobile Joy’, Mojo is a headphone amplifier and DAC (digital-to-analogue convertor) that empowers smartphones to deliver music content at up to studio-master-tape quality.

    Low-cost, widely available apps, such as Onkyo’s HF player (iOS and Android), now make high-resolution music files playback easy from all smartphones. Mojo connects to these devices digitally, processing the files using the most advanced conversion technology available, to deliver genuinely unrivalled sound quality to up to two pairs of headphones (You can use any pair of headphones with Mojo, from 4Ω to 800Ω.

    Mojo has three digital inputs; Micro USB, optical, and Coax, and has been designed to work with your iPhone, iPad, Android phone (USB OTG), Android tablet (USB OTG), Windows phone, Windows tablet, Mac, PC, and Linux computer.

    Despite Mojos ultra compact form, Mojo takes just four hours to fully charge and can deliver up to ten hours continuous use. But, thanks to Mojos separate Micro USB charging port, you can play and charge at the same time. External power banks can be used to charge Mojo on the move so long as they have a 1 amp output.

    Mojo is capable of playing all of today’s music formats, including the very latest high-resolution standards. It can deliver breath-taking realism from any digital music file: PCM; WAV; AAC; AIFF; MP3 and FLAC. It is designed to work with all smartphones and music players and covers specialist high-resolution formats such as DoP DSD files: DSD 64; DSD 128 and DSD 256. Mojo’s three high-resolution digital input options comprise optical (to 192kHz), plus Micro USB and RCA (mini-jack) which operate at up to an incredible 768kHz.

    Mojo is entirely designed and manufactured in England.

    "Chord's Phenomenal Little DAC"
    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.
     

     
    Packaging
    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.
    Sources used; 
    (1) Windows 10 PC - Jriver 22 - ASIO - 16/44.1 WAV CD rips
    (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.

    5.0/5,
    "They kept saying more musical, they were right !!"
    Pros - More powerful than you might think, Musical
    Cons - Get's pretty hot (normal), not great for a straight DAC because it has no true line out, Much prefer a Volume Knob (especially if you are in a hurry)
    Equipment to compare.
     
    iFi iDSD Black Label AMP/DAC (returned)
    Beyerdynamic T1 2nd Gen Headphones (returned)
    Meridian Explorer 2 AMP/DAC (returned)
    Beyerdynamic A20 Amp (returned)
    HiFiMan X V2 Headphones
    Chord Mojo AMP/DAC
     
    When I received the iFi I thought for sure that it was the winner.
     
        The bass boost feature was very nice (very mild boost) and had lot more power than Explorer 2.
        The iFi has 3 gain settings, Eco, Normal and Turbo.
            On Eco it was slightly less power than the Explorer 2.
            On Normal it had quite a bit more power than Explorer 2 and similar power to the A20.
            On Turbo it added like another 25%. It had the detail of the Explorer and the Bass of the A20.
     
        iFi iDSD also could function as my USB to SPDIF/RCA for the DSP 5K's (eliminating my need for M2Tech Hiface2). Really nice package.
        The ifi driver behavior was also flawless. Where when I bounced around a lot between apps and bit rates with the Explorer 2 it would occasional get wedged.
     
    When the Mojo arrived I almost didn't open it.
       How much better could it be in such a small package 1/3 the size and spec of 35 milli watts into 600 ohm.
       Also to top that off the slimy place I got it from had a ribbon around the box with 20% restocking fee if opened.
       But I had to know and knew I would not bother ordering another without restocking fee since I was so happy with the iFi.
       So I opened it. I am so glad I did.
       So many reviews kept saying "more musical". Well I have to agree. It is more detailed, without being bright or harsh. The bass is awesome without any boost.
     
       The whole package is a bit odd. I really prefer a simple volume knob instead of the quirky buttons. But it sounds too good to not keep it.
       The Mojo also has PLENTY of power to even drive 600 Ohm headphones. It is probably around the "Normal" range of the ifi.
       The iFi would be more Musical and engaging if I turned it up fairly loud, like some speakers.
       But the Mojo was engaging at modest volumes. Kind of like Meridian speakers do (I have ton invested in Meridian)
     
    #1) Mojo ($529)
    #2) ifi iDSD BL ($400 on sale at Adorama)
    #3) Explorer 2 ($200)
    #4) Explorer 2 ($200) with A20 amp ($350 for A20)
     
    I could have tried every combination because they can all function as an Amp or DAC Only (Except Explorer 2 cannot act as an Amp only).
    I really wanted the iFi to win because I really liked the features, package and price.
     
    I heard way more improvement with both iFi (on 600 ohm cans) and Mojo (on both headphones) than I strained to hear with MQA.
     
    iFi participates on Head-Fi.org but I believe it's a marketing person and is a total turn off. Blabbing about # of cores and the credentials of the developer. He then starts babbling about Ada programming language that the Developer used years ago, with Wikipedia links, so bizarre, so weird.
     
    Anyway to Quote John Atkinson of Stereophile Review
     
    All I can say is "Wow!"
     
    P.S. If buying on from FatWyre, avoid them due to 20% restocking fee. Always buy from "Fullfilled by Amazon" when possible.

    Sound / Comparisons:
     
    The Chord Mojo. A tiny black-box that recently received widespread attention from audiophiles everywhere. Does it outperform other portables and set a standard of quality for what you can obtain nowadays for $599?
     
    Upon first listening, I really didn’t want to analyze the sound characteristics of the Mojo.
    It just sounded so comprehensive and involving that I didn’t feel any particular characteristic of the Mojo that stood out. Call it a clear and musical corridor to your music.
     
    There’s a startlingly good sense of space with instruments and details suspended softly in the foreground. Don’t get me wrong. While musical and easy to listen to, the Mojo is extremely resolving and can be a razor-thin tool that reveals every tiny nuance in the recording.
    I can definitely hear the influence of the Hugo’s sonic character. It’s this trademark Chord quality where the music is not only hyper-detailed/accurately portrayed, but it sounds darn good too.
     
    But while the Hugo can tend to sound a tad sterile and lean, the Mojo somehow manages to provide ample enjoyment in a smoother signature.
    I’m not sure if this is due to the changes of the amp section on the Mojo, but it somehow seems to seamlessly blend music together and inundate you with its energy and power.
    The Mojo also brings out the best of the Ethers; the Mojo sounds so realistic and natural with classical and vocal tracks in an expansive landscape. I had hours of listening pleasure on highly technical songs where there’s a need to portray ambience and atmosphere.
     
    The closest to the Mojo is the iDSD, both have excellent details and speed while maintaining a naturalness to the music that just can’t be achieved by the Microstreamer, ODAC, etc.
    But in terms of space and dynamics, the Mojo is closest to the Concero HP. Both have impactful tight bass, and well-extended treble that is never sibilant or hot to the ears.
    The standout feature of the Mojo, however, is the super sweet mid-range that just always sounds melodious and tonally right--without hints of odd coloration or artificialness.
     
    The Mojo is a huge hit in my opinion, providing the dynamics and resolution of a full-size desktop setup in a bite-size package. It’s miles ahead ahead of lesser offerings, and this becomes immediately apparent when you listen to it extensively.
     
    Pros: Musicality, Expansiveness, Detailed, Performance lives up to expectations!
    Cons: Gets hot, Simple overlay (like it or not), Volume control lag, Stock USB cable hiss
     
    Overall Score: 9.5
     
        -Bass: 9
        -Mids: 10
        -Treble: 9
        -Transparency: 9
