Chord Mojo 2 Portable DAC & Headphone Amplifier Review & Comparison | Moon Audio
The Chord Mojo 2 is the most advanced DAC/headphone amplifier in the world. It plays your favorite music with class-leading detail and clarity, right up to studio-grade levels. The Mojo 2 builds upon the original Mojo by Rob Watts and makes some substantial improvements in the overall functionality of the portable DAC. The new Mojo retains a lot of what made the Mojo 1 popular: dual headphone jacks, amazing build quality, control spheres, great battery life, and a soundstage and tone that few could compete with. The Chord Electronics Mojo 2 adds additional functionality, including enhanced tone controls, a revamped menu system, high-end sound specs, and low and high gain volume control. The Mojo 2 is the perfect portable DAC amp for almost every headphone and IEM on the market.
The Chord Electronics Mojo 2 is the new king of portable DAC Amps that every audiophile should have in their system. It improves on the original in every way possible. Easily improve the sound fidelity from streaming services like Spotify, Tidal, and Qobuz, the Mojo 2’s tone control can make lossy and lossless audio sound much better than your consumer-grade devices. Chord’s internal noise-shaper allows the EQ to work linearly below 104 bits, and the more extensive controls allow for much more nuancing of treble, high treble, mids, and lows than before. Battery management has improved with the new desktop mode. The Mojo was already the best. Now it’s just better.
The British designed, engineered, and built Mojo 2 is distinctly different from all other devices, Mojo 2 uses proprietary British digital audio technology perfected over more than two decades, coupled to a powerful ‘FPGA’ processor. The result is class-leading sound quality both on the move or at home, with the power to effortlessly drive any headphones. For music just as the artist intended, Mojo 2 brings you closer to the music than any other portable.

The Chord Mojo 2 is not MQA-certified.
Yes, the Chord mojo 2 can provide up to 4.2Vrms (90 mW 300ohms) or 5.2Vrms (600 mW 30ohms). It can provide enough power for most full-size headphones and in some cases two headphones simultaneously (depending on power ratings).
The Mojo 2 is a portable headphone amplifier and DAC. You connect it to your source device like a phone or computer, allowing you to have much better audio quality than the phone or computer itself. Connect the Mojo 2 to your device using a compatible cable depending on you port selection. The Mojo 2 should, in most cases, be automatically recognized and redirect the audio through the Mojo 2 to your connected headphones.
The Mojo 2 is a portable headphone amplifier and DAC. The amplifier section provides power to your headphones, much more output and headroom than your phone or computer can output. The digital-to-analog section does just that: converts your digital data to an analog signal so that it can be outputted as an analog wave to your headphones for music listening. To learn more about how DACs work, head over to our "What is a DAC?" guide. You'll have much better sound quality using your Mojo 2 than you will direct from your phone, tablet, or computer.
Yes, since the Chord Mojo 2 has the same footprint as the original Mojo and the same connections, the Chord Poly will work in the exact same way. Simply connect the Ply to the Mojo 2 like you would with the Mojo 1.
When connected to the Chord Mojo digital to analog converter (DAC) the Poly is a “fully fledged” high-resolution wireless network music player, streamer, SD card playback device with high-resolution wireless playback controlled by your smartphone. The Poly connects seamlessly to the Mojo and Mojo 2, with precision design the two devices act like one when connected. It works with both the Mojo 1 and 2, and makes a great addition to your portable HiFi setup. Head over to the product page to learn more about the Chord Poly Wireless Streaming Module for Mojo.
DAC’s are one of the easiest ways to improve the quality of your music. Unless your streamer or all-in-one already has a high-end digital-to-analog converter, you do not necessarily need a standalone DAC. Some people prefer the sound of a particular DAC and may even use it in conjunction with their all-in-one units.
Yes, if you are connecting your Mojo 2 DAC to a consumer device like a smartphone or laptop, you will experience a superior music listening experience. The DAC is made to convert your digital data to an analog signal much more efficiently than your consumer device.
A DAC certainly will improve the overall quality of the music you are streaming from your source device. Another factor that can improve your streaming experience is to make sure you are streaming your music at the highest possible fidelity. Many streaming services offer a number of sound quality options based on your data consumption, and whereas high-resolution audio uses the most data, it will also offer the best sound quality.
Yes, up to DSD256.
In most cases, devices like the Chord Mojo 2 will come with both. There are standalone DACs and AMPs, however, and in every case, you will need both to listen to music. Now consumer devices like smartphones and laptops have both, but they are never up to audiophile quality. Having a high-end DAC will allow your music to sound better, more dynamic, and more resolute. Typically, an amplifier is needed when you do not have enough power from your source device to power your headphones or speakers. In the case of some headphones, you will need extra power to make sure they are driven optimally. Oftentimes, a DAC and amplifier are used when your source device, like an iPhone, does not have a headphone jack. If you have easy-to-drive headphones, then in most cases a standalone DAC will be sufficient for music listening. As always, Contact Us if you have any questions.
Use the included charging cable in your packaging to connect the Mojo 2 to a USB-powered source. Connect the micro-B connector to the port on the Mojo 2 with the battery icon to charge.
The Mojo 2 has 40,960 tap filters.
If you have an iPhone you will need to connect the Mojo 2 via the USB cable and a proprietary CCK adapter from Apple. If you have an Android phone, then a USB-C to USB-C cable will work for data transfer or a USB-C to a micro-B cable (depending on your connector type).
Poly cannot detect a connected MOJO/MOJO 2. Please ensure that your MOJO/MOJO 2 is switched on and connected.
Implementing a charge function into the USB-C port would cause unwanted noise, which does not align with Chord’s philosophy of product design. Secondly, USB fast charging causes unavoidable damage to lithium cells. This is not appropriate for a product with an intended lifespan of above 3+ years.
Chord has continued the previous layout of Micro-USB inputs on Mojo2 in order to maintain compatibility with the Poly streaming device. Many customers have invested in our streaming products and we will continue to support and develop them.
Single-ended is innately more transparent than balanced as it’s simpler. Secondly, pulse array DACs are single-ended, so going balanced would make it sound worse. Conventional DACs are balanced to solve substrate noise, but the pulse array is discrete so doesn’t have this problem in the first place.
To connect an Apple iPhone or iPad to Mojo 2, use a (genuine) Apple Lightning to USB adaptor (camera connection kit), connecting a suitable USB to Micro-USB or USB to USB-C to attach to the Mojo 2.
No, the analog OPs are the same. The biggest change on the analog side has been removing the coupling capacitor, which has tightened the bass with an extended definition.
The original Mojo was 38,912 taps, Mojo 2 is 40,960. Not a huge change, but the filter core is upgraded to current standards, which is a larger change than the taps; there is more to our WTA filters than taps.
On the original Mojo, the amplifier was fed by the battery directly. Now, it is fed by regulators, ensuring low PSU noise. We can see the benefit in that crosstalk (noise that came from the PSU) is considerably better with Mojo 2 at 118 dB.
It’s similar to Mojo, but benefits from a higher capacity.
The line-level mode has been removed for safety; Chord had a few cases of customers inadvertently activating it when switching Mojo on. They have decided to remove it and make it a user-conscious event now, so by manually having to increase the volume, it’s easier to understand/remember it has been done. Mojo 2 still remembers volume setting afterward, so if you want to use it as a line-level DAC, you don’t need to set it every time.
