We compiled a list of the best portable DAC/Amp combos that are great to use with mobile devices (iPhone and Android).

A portable DAC/Amp is a multi-purpose device. It accepts a digital input, converts it into analog audio, amplifies the signal, and finally outputs the music to headphones. Since we’re talking about portable devices, it also has to be small enough to fit into a pocket.

Missing headphone jacks from the current batch of phones have also warrant the use of an intermediate device (or Bluetooth connection) for headphone listening.

If you have to connect something, why not choose a terrific sounding replacement?

12 Best Portable DAC/Amp Combos in 2021

Here’s our pick for the best portable DAC/Amp combos in 2021:

Audioquest Dragonfly Cobalt

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 24/96
• DSD: N
• MQA: Y
• Bluetooth Input: N
• Output Power ([email protected]): ±135

The diminutive Dragonfly Cobalt is the newest TOTL revision of the much-loved Red and Black models (originally released in 2015). It shares the same digital volume control, MQA renderer, and 2.1v headphone output as its predecessors. The new DAC chip improves power consumption, reduces interference, and improves the overall sound over the Red and Black dragonflies.

The dongle style makes it super easy to just plug into a computer USB port, but does require a separate adaptor cable for portable use.

Power is sufficient for most headphones, but particularly inefficient or high-impedance headphones may cause the Cobalt to struggle to provide adequate volume. However, for headphones under 250 Ohms, the Cobalt provides a clear, crisp, and resolving sound, all housed in an attractive and tiny package.

Chord Mojo

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 32/768
• DSD: 256
• MQA: N
• Bluetooth Input: N
• Output Power ([email protected]): ±410

With reportedly more than 70,000 units sold since its October 2015 release, Chord’s Mo(bile) Jo(y) has become a personal Hi-Fi style and design icon. Immediately recognizable and passionately loved by many, the Mojo remains a staple for audiophiles on the go.

Undoubtedly, the most distinctive design elements of the Mojo are the 3 round glowing buttons. These act as multipurpose indicators of volume level and bit rate, while also functioning as volume and power controls.

It’s the chip and implementation that sets the Mojo apart from other DACs on the market. Rob Watts, Chord’s lead engineer, designed a custom DAC based on an FPGA chipset.

The Mojo embodies all the standard audiophile descriptions for worthy sound. It’s oh-so pleasing and engaging. It’s warm and musical, balanced but energetic, clean, clear, and transparent. Detailed and natural. Powerful but controlled.

It works great with IEMs, but the diminutive size belays the power and ease that it can drive difficult-to-power, full-sized headphones.

• Bluetooth Input: Y
• Output Power ([email protected]): 240

The FiiO BTR5 is a capable Bluetooth DAC/AMP that would give most headphones a wonderful upgrade without compromising on quality.

There is a lot of technology squeezed into the BTR5: one-touch NFC pairing, quality dual DAC setup, comprehensive Bluetooth audio format support, USB DAC support, OLED display, native DSD support, digital filters, and a balanced headphone output. The filters make no difference to the music and do not add value to the entire experience. But if you are someone who likes to tinker with settings, you will not feel out-of-place.

The look and feel of the FiiO BTR5 are minimal and modern looking with its curved edges and rounded corners. The oleophobic coating on the glass gives it a silky and smooth texture. The amount of engineering work that went into this portable DAC/AMP is evident. The long and slim form factor of the BTR5 makes it easy to slip it into pockets.

iFi Hip-DAC

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 32/384
• DSD: 256
• MQA: Y
• Bluetooth Input: N
• Output Power ([email protected]): 400

The iFi Hip-DAC offers most of the benefits of a portable DAC/Amp paired with a very reasonable price tag. It’s a very solid performer, with not quite TOTL specs, but does include both DSD and MQA support.

The internals of the Hip-DAC are based on iFi’s desktop-based Zen DAC but have been modified to work from a battery. iFi claims up to 12 hours of usage on a single charge, but tests show that battery life is far shorter when used with difficult to drive full-sized headphones.

The Hip-DAC sports both a 3.5mm headphone jack and a balanced Pentaconn 4.4mm for additional power and separation. It is about the size of a smartphone, so it is neither the slimmest nor largest pocket option out there.

The sound of the Hip-DAC is consistent with other iFi products, in that it is non fatiguing and balanced. Overall it maintains excellent detail and dynamics. The inclusion of an X-Bass button will be appreciated by anyone who wants a bit more low-end performance from their headphones.

iFi Micro iDSD Signature

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 32/768
• DSD: 512
• MQA: Y
• Bluetooth Input: N
• Output Power ([email protected]): 950

The ifi Micro iDSD Signature is the second upgrade to the popular Micro iDSD after the Black Label (BL) version came out in 2017. This time iFi decided to go with a classy and distinct Space Blue color for the solid aluminum chassis.

The Micro iDSD Signature is a very feature-rich device, including multiple digital filters, IEM match mode, multiple output power settings, XBass, 3D sound, high-power output, a balanced 4.4mm Pentaconn socket, and dual DAC chips. With top-notch bit-rate and sample rate support, as well as DSD and MQA, the only obvious feature the Signature is missing is Bluetooth.

The inclusion of XBass and 3D sound adds more tangible end-user controllable audio settings than the typical filter options included with the competition. They aren’t going to be useful with every headphone or IEM, but they do allow you to significantly tailor the sound to your liking. Output power is more than sufficient for almost every headphone.

xDuoo XP-2Pro

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 32/384
• DSD: 256
• MQA: N
• Bluetooth Input: Y
• Output Power ([email protected]): 300

Flexibility is the word that best describes this new iteration of portable DAC/Amps like the XP-2Pro. Finally, with the advent of high-quality codecs and proper Bluetooth functionality, wireless high-fidelity is becoming a reality.

The XP-2Pro functions as a wired amplifier, a wired DAC, or a Bluetooth DAC. The XP-2Pro has fit itself into a sweet spot of affordable, high-quality portable audio. It can function as a portable or desktop DAC/Amp, will properly drive most headphones and support a wide variety of connection methods.

The $140 Pro is (unsurprisingly) the revised version of the previous XP-2 model. While the internal DAC chip remains the same, the new Pro version adds more power output, advanced codec support, higher bitrate playback, and a more elegant design.

The XP-2Pro features flexible connection options (AUX, USB, and Bluetooth), attractive fit and finish, high-quality codec support, an internal battery to preserve the source battery, enough power for the majority of headphones, and clean and clear sound.

xDuoo XD05 Plus

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 32/384
• DSD: 256
• MQA: N
• Bluetooth Input: N
• Output Power ([email protected]): 1000

The xDuoo XD05 Plus is a well-implemented design with excellent format support, a plethora of connection options, outstanding power, and very good sound quality. Not to mention that it is an amazing bang-for-the-buck value proposition, especially since the Plus can do double duty as a desktop DAC or amplifier. The included accessory bundle is the complete package I’ve ever seen. There’s even an optional inexpensive Bluetooth module add-on available.

The XD05 Plus delivers power in abundance but is a bit too much for sensitive IEMs. The imbalanced volume potentiometer at the lowest volume levels further exacerbates this issue. Too much power, not enough subtlety.

However, paired with full-sized headphones, all that power delivers in spades. The Xduoo XD05 Plus is clear and dynamic and doesn’t overtly color or change the sound. Lots of digital filter options and the ability to swap OpAmps is further icing on the sonic cake.

Earman Sparrow

Key features

• Max Bit Rate/Sample Rate (Bit/kHz): 32/384
• DSD: Y
• MQA: Y
• Bluetooth Input: N
• Output Power ([email protected]): 125

By popular request, we have added the Earman Sparrow to this year’s ‘Best Of’ list. The Sparrow has wowed many reviewers (and owners) this year with its high-quality construction (aluminum case with 2.5D glass), robust feature set (balanced output, DSD and MQA support), and outstanding sound quality.

Earman (a subsidiary of high-end manufacturer Auris Audio) has created a teeny-tiny, itty-bitty, truly-audiophile device. The Sparrow features a gold plated PCB, high-grade components, and is assembled in Europe.

The Sparrow is first and foremost an IEM amplifier. Although it does have a 2.5mm balanced headphone jack (which increases power output) it simply doesn’t have the ability to properly drive inefficient full-sized headphones. However, paired with resolving IEMs, the Sparrow’s slightly warm signature really brings extra depth and fullness to the music.

Fidelity is remarkably refined for a device of this type, and the Sparrow is defined by its smooth and thoroughly enjoyable sound.

FAQ

Why add a DAC/AMP to your portable setup?

There are several excellent reasons for adding a separate DAC/Amp to your portable setup, including:

• support for higher quality file playback
• better sounding conversion from the digital to the analog domain
• sufficient power on hand to properly drive difficult headphones

Of course, this means you are going to have both your phone and a portable DAC/Amp in your pocket. Consequently, device size may be an issue for you. For some, tiny, ultra-portable dongle style DAC/Amps will be a better alternative than larger (but typically more powerful) portable options. Your use, pocket size, and choice of headphones all need to influence your decision.

All portable DAC/Amps must be connected both to your phone and to the headphones. Typically, this is done with cables to guarantee the highest sound quality, but some offer Bluetooth connectivity as well.

Bluetooth certainly improves usability when using your phone for any other purpose while listening to music. It is far easier to use your phone if it isn’t tethered via elastic bands and cables to a bulky DAC/Amp beneath it.

Why not use a DAP to replace a portable DAC/AMP?

A separate Digital Audio Player (DAP) is an alternative to adding a portable DAC/Amp to your on-the-go setup. However, since most of us are going to carry a phone anyway, why add a potentially expensive DAP as well?

While basic DAPs are fairly economical, models with high output power, or with support for streaming services (something that is baked into just about every smartphone these days) means that a more feature-rich and pricey DAP purchase is required.

And there’s only so much room in our pockets after all.
