Part of the “Before You Buy” Series

Greetings mate and Welcome aboard. Stuart Charles here, HomeStudioBasics.com helping YOU make sound decisions leading to a beautiful audio experience that will make you fall in love with music (NOT gear) all over again, so…

Before we get into the Chord Mojo Review, grab a snack, sit back and relax because…

You’ve come to the right place!!


This little mini-ramble has a purpose, so bear with me.

Since venturing down the audiophile rabbit hole, I’ve come across very few Amp/DACs that have truly blown me away.

There have been many I was impressed with, but only a few really stood out.

As far as clarity and cleanliness, definitely, Objective 2 is definitely tops in the entry-level desktop category.

Note: Objective 2 has since been discontinued and replaced with the ATOM.

The other in the high-end category was the $1400 Bryston BHA-1 Headphone Amp playing “Over the Hills and Far Away” by Led Zeppelin.

It was the first time I had ever truly heard a song in the way that I felt the artist intended.

It’s a track that I’ve listened to a thousand times but with the HIFIMAN HE400i, the Bryston, and the good source file it was like hearing it in a completely different light.

The clarity, dynamics, instrument timbre, resolution, everything.

It was all picture-perfect and something I haven’t experienced since.

I also can’t forget the Sony MDR-Z1R paired with the TAZH1ES Headphone Amp playing back high-quality source files.

That’s a combo that should be heard by everyone at some point.

Michael Jackson’s Billie Jean and Ants Marching by Dave Matthews were particularly noteworthy for their sense of raw energy, Soundstage, and air.

It was almost like being among the artists.

The only other time I got those same sorts of feelings was with the Mojo + Dan Clark Aeon Flow.

The Best Headphone Amps & DACS

Enter the Mojo.

Not expecting much, I paired one with the MrSpeakers Aeon Flow Closed, pressed play, and was completely obliterated by the intense and intimate wall of sound penetrating my brain.

The Flow is a perfect example of an upper-echelon type of product that is truly worth the investment.

It combines every good quality that a headphone should have and offers it at a pretty affordable price.

Because of the law of diminishing returns, after the $300-400 mark, you’re getting a smaller and smaller improvement in sound quality relative to the astronomically higher prices you’ll inevitably pay.

The Flow is kind of an exception to that rule. I absolutely would recommend it if you’re in the market for a good closed-back.

Pairing a headphone like the Aeon Flow with an Amp/DAC like the Mojo is something I believe to be an end-game combo for most people.

There’s simply not much else you would ever need besides an open-back headphone to compliment it.

The truth of the matter is that as far down the rabbit hole as I’ve gone, the differences in outrageously priced gear are not worth the investment in most cases.

There are some exceptions, but even then, the high price is rarely warranted when you start to think about it.

For example, the Focal Utopia are the best and most natural-sounding headphones I’ve ever heard, hands down.

It’s a sound signature that is as close to perfection as you’ll find.

The Best Headphones for Gaming

The King.

Is it worth $3000-4000? Eh, probably not. But for $1000-2000? I’m leaning towards yes.

I look at it this way: If you don’t ever plan on buying another headphone ever again, I would say the Utopia is most certainly worth it, given that you have that kind of disposable income lying around.

Differences in actual headphone sound signatures are much more discernible than the differences from one Amp/DAC to another.

Most of the discrepancies come in the form of pure spec sheet variances like power output and the like.

The HA-2 provides 30mW of power into 300 Ohm, which just makes the cut for my HD600.

The Mojo has much more than that, outputting 35mW into 600 Ohms.

You can see the difference, as it will output much more into 300 Ohm though there’s no official number (to my knowledge) available.

Now even though the differences between the HA-2 and Mojo aren’t astronomical from a musical standpoint, which would I rather have?

That’s an incredibly easy answer as I would take the Mojo every day and twice on Sunday.

Let’s find out what makes it so good…

On to features!


Features

& Usage


First, we’ll start with some basic functions of the Mojo that you should be made aware of.

This Amp/DAC is admittedly a bit finicky and temperamental, but once you understand how it prefers to be handled, it becomes second nature and fairly straightforward.

Do be forewarned though: this isn’t your typical average Joe.

Before you do anything, charge your Mojo for optimized testosterone-fueled fun.

This is often overlooked and can lead to some initial frustration as most Amp/DACs do not need a charge at all.

It’s like a dude with low T; he’s kinda flabby and tends to complain a lot.

This is what the Mojo will do if it’s not charged. “I don’t WANNA play music today!” Lol. Wahh.

Anyways…

I used a standard 2.1A wall wart.

Use the micro USB slot that has a lightning bolt over top for charging.

The other slot is for connection to a PC/Laptop via USB.

It takes roughly 4 hours to charge for 10 hours of playback. I suppose this is one of my main gripes about the Mojo.

I just want to be able to quickly play music at any time, and unfortunately, that’s not 100% possible as you’ll need to charge the unit fairly frequently depending on personal use.

Still,

if you just treat it like charging your phone, it shouldn’t be that big of a deal.

You can also charge it and play back music at the same time if you have two micro USB chords.

These are fairly common and cheap so definitely pick some up.

Just keep in mind the unit will run fairly hot. This is normal but you’ll still likely be taken aback by it.

I wouldn’t recommend just using your PC’s USB port to charge this beast, as it will take about 10 hours and isn’t practical at all.

Fortunately, this becomes somewhat of a minor concern when you consider the package as a whole.

Chord Mojo USB DAC Review

Check the led indicator for the Mojo’s charge status.

It’s located under the second micro USB slot (lightning bolt).

This is also a source of confusion per my research and experience.

I’ll make it simple.

The color of the light indicates the battery level. Blue = Fully Charged. Green = 75%. Yellow = 50%. Red = 25%. Flashing Red = <10 minutes life.

  • Once the Mojo is fully charged, plug it into a USB slot on your PC.

From there, hold down the power button globe ball for 2 seconds.

After you hold the power globe for 2 seconds, the Mojo will turn on, and the volume globes will also display colors.

The unit should be recognized by your PC almost instantaneously.

Once it is, find it in your Control Panel’s Sound section.

It should say “Chord Async USB 44.1kHz – 768kHz.” Right-click and set it as your default device!

Take note of the different colors on the power button and what they refer to.

When you’re playing back music, the power button globe will display many colors depending on the sample rate of the song in question.

Red = 44.1kHz. Orange = 48. Yellow = 88. Green = 96. Light Blue = 176. Dark Blue = 192. Light Purple = 352. Purple = 384. Plum = 768. Light Plum = DSD.

Take note of the volume colors.

The volume buttons also change colors depending on how loud or quiet you’re listening.

The pattern seems to mimic the above pattern for sample rate upon intense examination.

On-Board Features

As far as music enhancement features, it’s bare-bones.

There is no gain switch or bass boost, but a unit like this doesn’t need any of that given its raw power and ability to drive any headphones with plenty of headroom left over.

There’s zero distortion even at high volumes as well.

Connections

The Mojo features 2 micro USB slots (mentioned above), Optical out, and Coax.

It can be paired with anything that allows audio out via these connections.

Some examples include your console, PC/Laptop, Smartphone, tablet, music player, DAP, etc.

It also has 2 separate 3.5mm headphone jacks for easily comparing headphones as well as gaming/music/movie sharing with someone.

Pretty neat and nifty!

For gaming, you would simply purchase an optical cable such as this one, and run one end from the back of your PS4/Xbox to the Mojo’s optical input.

Then run the USB from the front of the console to the micro slot on the Mojo. We’ll get into more specifics in a bit!

Let’s look at the build.

EASE OF USE: B


Build Quality


AudioQuest DragonFly Red vs. Cobalt vs. Chord Mojo

Volume Globes and Power Globe.

The build of the Mojo is quite solid.

In fact,

I love how heavy it feels in your hand, and even though it’s also very portable, it doesn’t feel cheap at all.

It weighs about as much as you would expect given its price.

For comparison’s sake, the FiiO E10K is solid but does feel like a $75 unit.

The E10K also doesn’t have an internal battery and is bus-powered, but that’s neither here nor there.

I love the globe balls on the Mojo and thought it was a nice touch that separates it from other Amp/DACs.

They feel cool and are very responsive.

Sometimes I would rather turn a dial when desiring more volume, but it’s a minor nitpick.

For the most part,

I love the way the buttons function, and all of the input jacks are very rugged.

It’s a unit that looks like a toy in pictures, but once you handle it you’ll realize how much work went into the product.

BUILD SCORE: A-


Ergonomics


AudioQuest DragonFly Red vs. Cobalt vs. Chord Mojo

Coax, Optical, Charging, Listening.

The Mojo provides a ton of power and plays files up to 768kHz.

For comparison’s sake, most sources come in at 44.1 which is plenty.

In addition to that,

it provides 35mW into 600 Ohms, remains crystal clear at high volumes, and provides plenty of headroom for 99.9% of headphones. 

ERGONOMICS SCORE: A+


Sound


MrSpeakers Aeon Flow Review

Absolutely Breathtaking.

I had mentioned at the start how the Mojo paired with a MrSpeakers Aeon Flow was absolutely sublime.

The intimacy that it provides is really what sets it apart from other Amp/DACs.

The sound just comes across as more realistic and natural.

While some Amp/DACs seem a bit forced, the Mojo is effortless in how it portrays the sound to you.

You kind of get a sense that you’re up close and personal with the artist, and this is especially true with female vocals.

The sound demands your attention in a way that kind of makes you stop everything and analyze.

It does so in a manner that isn’t abrasive, harsh, or claustrophobic.

Not only that, but it seems to improve everything that your favorite headphone does.

Anything ranging from Soundstage, detail retrieval and resolution, dynamics, clarity, atmosphere, texture, instrument timbre, vocal intimacy, attack, sustain, and decay.

Note: I’ve since become a lot more jaded about Amps & DACS (as in, DACS, in general, don’t really make headphones sound better per se), but the Mojo is still a product that stood out to me so take that for what its worth.

I believe after the Mojo’s price point, it becomes a lot harder to detect differences in sound quality from a strictly Amp/DAC standpoint.

There will always be marked differences in certain types of headphones, as they are tuned differently and have varying sound signatures.

But, it’s much harder to discern the difference between various Amps and DACs.

Some DAC chips do outperform others, but by and large the differences in actual sound quality from DAC to DAC are fairly marginal.

The Mojo is a clear exception to this law of diminishing returns type of concept, and I do believe it’s worth every penny given what it did to my HD600s. More on that in a second!

SOUND SCORE: A+


Gaming


The Best Headphone Amps & DACSIt’s more of the same goodness. Part of your audiophile complete breakfast!

Clarity and micro-detail are astounding with this unit.

I would highly recommend a Mojo for something like FPS shooters and any game you might have or want to buy.

You’re going to get a sense of everything around you, to the smallest minute detail being felt and heard to an astounding degree.

Not only that,

but the sounds come across as a bit different.

Their natural character shines through in a transparent, raw, and honest way.

It makes you want to dissect the sound – where it came from, how it formed, and why.

As an example, the Sennheiser HD600 is most notorious for having a narrow image.

Its instrument separation is extremely good, but the Soundstage is a bit lacking as far as width goes.

I was shocked to find that the Mojo actually improves the Soundstage of the 600s a bit (at least in my head).

It’s not night and day or anything, but I definitely noticed a difference in width.

I got a weird out-of-my-head feeling a lot more times than I ever remember with the headphones out of any other amp.

At one point I even ripped the headphones off of my head because I thought the sound was coming from outside. I have a lot of barking dogs that inhabit the dog park outside my window which is extremely annoying.

I can’t remember the song in particular, but toward the end, I heard what sounded like those same barking dogs.

I ripped off the headphones in shock, thinking some dogs were barking close by. They sounded weird and gave me an uneasy feeling.

To my surprise, I rewound the song and the barks were actually coming from the track itself!

It came from the right and to the back.

So the Mojo in my estimation improved on the depth of the image as well as the width to a degree.

Still, this “out of your head” moment could simply be attributed to the track itself and nothing else – a concept I discussed here.

GAMING SCORE: A+


Hooking It Up

PS4 Set Up

(Xbox users will follow a similar protocol)


We already discussed in depth how to hook it up for a PC/Laptop, but with Gaming, it’s much more straightforward.

Steps

  1. Run an optical cable from the back of your PS4 to the Optical out on the side of the Mojo.
  2. Run a USB cable from the front of your PS4 into the micro USB slot on the Mojo. Make sure you plug it into the slot with the USB icon and not the charging port.
  3. Turn on your PS4.
  4. Hold the power button on the Mojo as you would out of your PC.
  5. Go to Settings > Sound & Screen > Audio Output Settings.
  6. Change it to “Digital Out.”
  7. The Input format should be Linear PCM.
  8. Go back to Settings > Devices > Audio Devices. The Output Device should say “Chord Mojo” or something similar.
  9. Plug your headphones in and turn up the volume to taste.

Check out the comparison I did to the xDSD and xCAN!


Closing Thoughts


After researching and hearing varying complaints over the years, I wanted to come back to this article and warn you of a few things before purchasing a Mojo.

I believe they have also discontinued the original but a version II is now available.

Here is a list of things to watch out for if you decide to pull the trigger on one of these.

  1. It runs hot. This isn’t too big of a deal for most people including me being that it’s a Class A amplifier.
  2. For many people, the battery fails to hold a charge – usually around the 1-year mark or before.
  3. Customer support seems to be non-existent in many cases.
  4. The unit dies unexpectedly or behaves erratically.

Even despite that, others have come to me and said that you can easily buy and replace the battery yourself without having to send it back to Chord and pay an expensive fee.

I had also read a review that said Chord wanted $200 to replace the battery, so he did it himself. This is simply not acceptable.

As for the burning question:

Is it overpriced?

It’s hard to say.

I think if you can get it for around $300 or less it’s a good deal if you don’t end up having any problems down the road.

The question is are you willing to take that gamble?

The Mojo indeed can be a bit finicky, but once you understand that it functions a bit differently than a standard Amp/DAC, you’ll likely forget you were ever mad at it.

Originally I gave the Mojo an A+.

After coming back to this article and shedding some more light on the situation, I think that grade dips to an A-/B+.

Update

I’ve also been thinking about it quite a bit and my infatuation with the Mojo may have had a lot to do with the Dan Clark Aeon.

I’ve talked to a few people about this and we all agreed that the Aeon tends to do an amazing job of mimicking speakers – to the point where it kind of does feel like the artists are in front of you at times.

This is especially alarming when you consider that the Aeon I demoed is a closed-back headphone.

The Shocking Truth?

So the shocking truth is that my obsession with this Amp/DAC may not have had anything to do with it at all; but rather the headphones and/or source file in question.

Still, the Mojo will always be memorable to me as it’s still up there with the best DACS I’ve tried. So ultimately I think it’s worth a look.

Hi, thanks for your review! I’m looking to get either the Aeon Open or Closed X, and am wondering if, two-point-five years later, you’d still recommend the Mojo to power these Am considering also Dragonfly Red or Cobalt, or the xDuoo XP-2 Pro

Whilst I’m here, any pref on the open or closed variants? I listen to all kinds of music, but more than anything want clarity and great sound for classical & instrumental music, mostly strings. Any recc’s would be great! I have a quiet house for listening, but many reviews have rated the soundstage of the closed above that of the open for these headphones.

Thanks!

My pleasure, L! Yeah a Mojo is still the best DAC I’ve heard, but you may want to check this out first: https://homestudiobasics.com/before-you-buy-a-chord-mojo-read-this/

I loved the Aeon Closed, haven’t heard the open. The Aeon is actually the best-closed back headphone I’ve heard, and I paired it with a Mojo lol. Musical bliss right there.

A DragonFly Red would most certainly be the safe purchase as it pretty much can’t die and has no issues. I’ve been using one for a couple of years now. Listening now actually but have it hooked up to a tube amp (xDuoo TA-20).

Keep me posted on everything! If you’re willing to take a gamble on the Mojo, it is a perfect pair with the Aeon closed.

Hey Stu, thanks for the review!
I love the Mojo too, sounds wonderful feeding my retro stereo system (HK680 and Mission 767). I use Foobar2000 with the kernel driver.
The Mojo’s quirks are easily forgiven by anyone who gets a good sit for a listen, it’s so involving and the joy doesn’t fade, it stays.
So, the main reason i wrote, is to add: it’s usb implementation is quite sensitive. I use el cheapo keyboard+mouse and suspect they are heavily polluting the usb hub with noise. The motherboard is a quite decent gaming one, but when the Mojo was connected to the same hub as the peripherials, i was very frustrated about the random sync losses and total freezes of the device happening quite often (sometimes only power cycling helped).
Once i moved the Mojo to a dedicated usb hub (what the motherboard luckily already had), all these issues are gone forever.
Hope this helps someone, all the best!

My pleasure 🙂

Nice! Thank you for that. I’m sure it will. I too have a sort of biased love for the Mojo and likely always will. Moments like that tend to stick out in your mind (Aeon Flow CLosed + Mojo). It was such a perfect combo that I have a hard time putting it into words.

Still, I think my obsession with the Mojo had more to do with the open nature of the Aeon Closed than anything. I had a discussion recently with someone about how that headphone did such an incredible job replicating speakers, and I think there’s a lot of truth to it. That wall of sound that felt like it was in front of me could have simply been the headphones and not the Mojo.

Even so, the Mojo is a great product imo and I still recommend it to people (so long as they understand its caveats).

I agree on your take on the Mojo. I have it as my default device in my home office, driving my HD6XX close to perfecion. I love the build quality, the globes and the colours for volume and different bit rates 😀
I use Roon for playback. This setup has worked well for years.

I have just placed a set of KEF LSX on my desk as my future desk speakers (replacing B&W MM1), but as they only take Optical in, I have just ordered the FIIO K3 2021 to connect my laptop to the speakers.

I am now thinking, if I can leverage the K3 to get a similar sound quality as my Mojo. You are recommending the Atom as a great addition to the K3 in the Best-of section.

To drive my HD6XX, how would the K3/Atom combo compare to the Mojo ?

Reply
Stuart Charles Black January 29, 2023 - 2:09 am

Hey man! Thanks for stopping by. Glad you’re enjoying everything! I would say the main difference is just output impedance and the fact that the ATOM is very clean and neutral. Plenty of power as well. K3 is similar sounding to ATOM but significantly underpowered out of the single-ended jack. I still use the K3 connected to my active speakers so it has its uses for sure. I just never use it with headphones.

hello, I’m in doubt between mojo and the Objective 2 combo (I even have it), with Cambridge dacmagic100. which one has the best sound?

Reply
Stuart Charles Black May 24, 2023 - 11:04 am

Gabriel,

Thanks for the comment! So if I’m understanding you correctly, you’re saying you have the Objective 2 paired with the Mojo? I’m not sure I would stop everything and fork over $200 (IIRC) for the DAC Magic. Good DAC though! I will say it has some extra features on the back so if you need those, it’s probably worth a look. As far as sound goes, I wouldn’t buy it expecting anything to significantly improve. Hope that makes sense! Let me know.

Hi Stuart,
thanks for the mojo 2 review, you helped me decide to buy it.
I’ve been using the mojo2 for two months now and I’m fascinated by the sound this little one presents.
I completely agree with you in everything, you wrote that it might be to the headphones or the source file, and I assure you that it is not. Mojo2 and audeze lcd2 is a sick combination in a good way, I can’t stop listening, all the songs sound like I’ve never heard them before.
That’s the reason I’m writing to deny “The Shocking Truth”, the sound produced by mojo2 is amazing, everything is so natural.
My setup so far included an objective 2 combo, onkyo receiver, akg k702 (with open bass port), denon c751 in ear.

Many greetings and all the best,
Jovan

Stuart Charles Black September 22, 2023 - 5:31 pm

Jovan,

Thank you for stopping by! I will say that it still is mostly the source file and the headphones though. The DAC plays a minuscule part. That said the Mojo is still a fine piece of equipment. It’s just not some miracle worker or anything like that. At the end of the day it’s still just a dac.

I’m really glad you’re enjoying it though! The LCD-2 has incredible resolution so that’s in large part what you’re likely hearing. It’s simply y amazing at picking up loads of subtle details and the separation of instruments and vocals is second to none. Get a really well mixed and mastered track and you’re pretty much in heaven.

Anyways, wishing you the best. Let me know if you have any questions in the future!
