Best portable DACs to make your music sing 2021
The best portable DACs, which stands for Digital-to-Analogue Converters, can make a huge difference to your listening experience. That’s because they make any music that you play from your phone and through your headphones not only sound clearer and crisper but easier, too. This brings you a better listening experience, which is much more like what the artists intended you to hear.Your phone, tablet, and laptop all have their own DAC built-in. But having a separate, dedicated device can improve the audio quality dramatically. Some of the best portable DACS of 2021 even come with added features, like Bluetooth connectivity, allowing them to pair wirelessly with your device rather than plugging them in.

Although it might not be the most exciting tech on the market, new portable DACs are often released. Most recently, THX, a name you may associate with cinema, has brought out a portable DAC (digital-to-analog converter) that could make your headphones sound incredible. It has a USB-C dongle on one end, a 3.5mm audio port on the other and works between your headphones and your PC, Mac, or Android phone.

Although we haven’t had the chance to trial the THX yet ourselves, if you’re interested in the sound-boosting features of an external DAC, check out our selection below. We’ve put the most popular models through their paces and created a guide to the best portable DACs you can buy today.

What is the best portable DAC?

best portable dacs: iFi xDSD

1. iFi xDSD

A DAC challenger to Mojo’s throne

Sleek, distinctive design
Analog volume control
More complicated than the Chord Mojo
Controls take some getting used to

It’s a close race between the xDSD and the Chord Mojo, but one thing’s for sure: the iFi xDSD is the best portable DAC of 2021.

The iFi xDSD is certainly eye-catching, with a ribbed metal casing and glossy finish giving a smartly premium look. Out of the box, you’ll also get a velvet carry pouch and even some strips of velcro (remember velcro?) to strap the DAC to the back of your smartphone if you’re into that.

The optional Bluetooth connection is hugely practical, utilizing an aptX compression format to stream wirelessly without needlessly impacting the audio quality. The Type-A USB is also much friendlier than the micro USB for connecting to either Android or Apple devices. (HiFi’s cheaper sister product, the iFi xCAN, offers much the same specs but as a dedicated headphone amp without the USB port.)

You’ll get the most benefit when using the fancier audio formats out there. Unlike Mojo, the xDSD supports the hi-res MQA (Master Quality Authenticated) format found on Tidal’s Master’s tier and the like. It’s able to play both DSD and PCM audio in their native formats, rather than converting one to the other – and risking further loss – before it reaches your ears.

Using the DAC gives a sense of careful control, aided by an analog volume wheel and numerous other settings to truly fine-tune your music, with separate settings for optimized mids (Listen) or frequency-agnostic (Measure) output. There are even options to gently boost the bass, or turn on the ‘3D+ Matrix’ for a live performance feel – widening the soundstage for a sense of scale and presence beyond usual stereo.

Some will love the level of control and experimentation this affords them, though others may prefer ‘one setting’ DACs that don’t require as much interference. The Chord Mojo (below) is still probably the natural choice for those wanting an industry-standard portable DAC that does the job in as few steps as possible.

The iFi xDSD seems to be sold out in the US and Australia, but it’s still available in the UK. For a stylish alternative, check out the iFi hip-DAC.


best portable dacs: chord mojo


2. Chord Mojo

The most widely known DAC for a reason

Powerful amplifier
Simple volume controls
Needs to be charged before use
Big and cumbersome

The Mojo is one of the larger DACs we’ve tested as a result of the onboard battery that needs to be charged before you can use it with your iPhone.

Having to charge an extra device – even if that charge lasts for 10 hours – before listening to music out and about is hardly ideal, but that’s the price you have to pay for the Mojo’s more power-hungry innards.

Thankfully the Mojo puts that power to good use, delivering a much rounder sound than the stock iPhone jack. Without the Mojo the treble and bass frequencies tend to take over but introduce the external DAC into the mix and the mids are much more present and full.

The device’s size means it’s a bit cumbersome, and not exactly an inconspicuous accessory. I ended up carrying the Mojo in my front pocket (where I could easily access the device’s volume controls), with the USB cable leading to my phone in my back pocket.

This probably won’t be your ideal setup, and that might mean leaving the Mojo behind when you’re going out on the town. Using the device at work, where I’m able to leave both my phone and the DAC on the desk, is a lot more user-friendly.

Other features include a second headphone output and a cool lighting feature whereby the volume buttons change color based on the quality of the music file being received.

3. Audiolab M-DAC Nano

Small DAC, powerful punch

Easy to use
Adds wireless capabilities to wired headphones
The 6-hour battery when upscaling
Not as versatile as some options

Don’t be mistaken by the M-DAC Nano’s diminutive stature – this is a powerful, pocketable piece of audio excellence.

A portable headphone DAC and amplifier at an affordable price, it’ll boost the audio performance of any device that sends sonics via a Bluetooth connection. It’s about as simple as this sort of gadget can get – simply connect the M-DAC Nano to your smartphone or Bluetooth player of choice, plug a pair of wired headphones into the Audiolab unit and away you go.

From here your headphones have a “wireless” connection to your phone, with a dedicated volume wheel on the M-DAC Nano. An “F” button on the unit enables 32bit / 384kHz upscaling, adding critical clarity and depth to your source’s output.

You’ll get 8 hours of playback with general use, and a limited but respectable 6 hours with the upsampling mode turned on too, driving headphones spec’d to 3000ohms with 7.5mw of power. Supporting Bluetooth V4.2 (with aptX, aptX Low Latency, and AAC codecs accounted for) it’s about as good a presentation as you’re going to squeeze from a mobile.

With the headphone jack going the way of the dodo and smartphone amplifiers improving slowly but not to the standard an audiophile would appreciate, the M-DAC Nano is an affordable upgrade for the on-the-go muso in your life at a mere $169 /£149 / AU340.

4. iFi hip-dac

The iFi hip-dac really hits the spot

Great design
Support for lots of Hi-Res Audio codecs
Balanced output as well as 3.5mm
No wireless connectivity

The iFi hip-dac is a great choice if you’re looking for a portable DAC that looks as good as it will make your music sound. With plenty of connectivity options and codecs supported, it’ll make the best headphones sound even better, thanks to ‘bit-perfect digital-to-analog conversion and a nifty bass-boosting button.

Coming in at $149 / £149 / AU$249, the iFi hip-DAC isn’t too pricey for the specs it offers, and it looks great, to boot. Its luxurious petroleum-blue and copper finish alongside its hipflask-like design (hence the name) means it is, weirdly enough, a DAC you really want to show off – and it’s small enough to slip into your pocket with ease.

It’s a shame that it doesn’t also have Bluetooth support and that Apple users need to buy an additional cable to use it, but overall, the hip-DAC is a fantastic piece of audio kit.


best portable dac: rha dacamp l1

4. RHA Dacamp L1

A big, beefy DAC/Amp with physical controls and iOS support

iOS support via USB
10-hour battery life
Physical dials are dicey
Limited types of inputs

It’s a close call between the Chord Mojo and the RHA Dacamp L1. While the Mojo offers a more compact form factor, the Dacamp caters to iOS users with a dedicated USB input. That being said, the Dacamp is a bit longer than the Chord Mojo and a fair bit heavier if you’re the kind of person who doesn’t mind hauling their audio gear around with them.

While it definitely fights for space in our already overcrowded backpacks, we genuinely love the Dacamp – it makes playback sound smooth even when playing music from some less-than-ideal sources and the adjustment knobs on the side allow you to do simple, subtle tweaks to the sound. The knobs might not offer the most robust of changes (more so than a software EQ, for example) but we appreciate their existence all the same.

It comes in a very close second here, but RHA’s Dacamp L1 is one of the better DACs to cross our desks and comes highly recommended.

5. iFi Zen Dac

An excellent entry-level desktop DAC

Smooth, relaxed sound
Supports high-impedance headphones
Built like a tank
No power supply included

If you don’t have much money to spend on your first headphone setup, the iFi Zen DAC is the perfect starting point.

This DAC and amp combo has enough power to drive power-hungry headphones while also working with sensitive in-ear monitors, making it extremely versatile. The iFi Zen DAC has more features than you would think for the price including support for MQA, DSD256, PCM384, DXD384. There are also balanced inputs, outputs, and the ability to bypass the amp if you want to use it solely as a DAC. While you may not use all of these features, it’s nice future-proofing as you mature during your audio journey.

Looking at the specs on paper, you’d expect the iFi Zen DAC to cost $500 or more but it retails for $129 / £129 (about AU$250) making it one of the best audio bargains today. Whether you’re just dabbling in headphone audio or if you simply want a somewhat portable DAC/amp to take on the go, the iFi Zen DAC is an excellent choice.

6. Audioquest Dragonfly Red/Black

The pint-sized Audioquest Dragonfly packs a punch

Very portable
No battery to charge
Lacks nuance
Little volume control

Audioquest basically invented the USB DAC with the original Dragonfly back in 2012, but until now the device’s power demands limited it to desktop use, thanks to the iPhone’s 100mAh limit on power draw through its lightning port.

But Dragonfly’s latest devices completely change that. By using an all-new USB microcontroller, Audioquest’s Dragonfly Red/Black’s DACs now consume closer to 25mA, and can now be used happily with any iOS device.

This makes the Dragonfly a pretty compelling iPhone DAC. With a total size smaller than most USB sticks the Dragonfly fits easily into a pocket alongside an iPhone.

Dragonfly Red is the more premium offering. It contains a better DAC chip and outputs 2.1 volts of power as opposed to the Black’s 1.2 volts. That means the Red is a better choice for driving high-impedance headphones.

With my headphones plugged directly into my iPhone, I was comfortable listening to music with the volume set halfway, but with the Red, I could listen at just a quarter and with the Black, this was strangely reduced to just one volume bar.

In effect, this means that you have a lot less control over the listenable volumes – turning the Black up just one volume notch meant that music was too loud, and turning it down one muted the iPhone completely.

Both versions, however, added a good amount of heft to the bass without sacrificing the clarity of mid frequencies. A play-through of Daft Punk’s Get Lucky didn’t shimmer in the same way without the DAC than with it.

Whether you’ll want to pay extra for the Red version depends entirely on how difficult your headphones are to drive – there’s far more of a difference with power-hungry over-ears than budget in-ears.

Neither the Dragonfly Red or Black can match the sophistication of the Chord Mojo, but their budget price and much more practical form-factor make for a far better portable listening experience.


creative sound blaster e5

7. Creative Sound Blaster E5

A wireless DAC for folks who can’t be bothered with wires

NFC for Android pairing
Wireless playback
Upscaling over Bluetooth
SBX function doesn’t add much

Creative Lab is a name you’ve heard before. It was the company that started the sound card craze in the late ’90s and became king of the audiophile crowd for a short period of time. In the time since, Creative has been hard at work crafting extraordinary triple-driver in-ear headphones and an 11.2.4 soundbar while simultaneously working on a portable DAC for more… uh, affordable price points.

The result of all that hard work is the Creative Sound Blaster E5 – the middle child in a large line-up of DACs that offers wireless connectivity options for those of us that can’t be bothered with a cord.

While the idea of wireless is a great one, it’s not without its limitations – Bluetooth can’t transmit music at CD quality without the help of more advanced codecs like LDAC or aptX HD. Because of that limitation, music over wireless just sounds OK. Sure, Creative can upscale it after it’s been received, but it never sounds quite as good as native Hi-Res Audio. Still, if wireless convenience is what you’re looking for to power those powerful headphones in your closet, the E5 is far from the worst choice you could make.

Why should I use a DAC?

The advantages of using an external DAC

The best portable DACs take the bits and bytes stored in a digital music file and convert it into something a headphone or speaker (analog devices) can playback.

The thinking behind DACs and amps is that when you press play on your phone or speaker, the sound that comes out often isn’t as the artist intended. We’ve found it should often be clearer, crisper, or offer up more bass.

Of course, you could just get used to how your phone plays music. But if you’re an audiophile that just won’t do. So, if your music isn’t sounding quite as spectacular as it should – and the only thing you’ve changed recently is the source – it’s likely that your new device (a new laptop, desktop, phone, or tablet) has a poor quality DAC built-in.
