Best headphone amplifiers 2021: budget and premium
If your high-end headphones sound too quiet or dull when paired with your computer or mobile device, you may need a headphone amplifier.
Powerful enough to drive most headphones, the diminutive DragonFly Red works best with computers because it needs to draw power from the connected source.
About the size of a small thumb drive, the DragonFly Red is very portable and, unlike larger battery-powered amps, is easy to leave connected to a computer. The battery life is rated for around eight to 12 hours of use. With the ability to connect via Micro-USB, optical digital, coaxial digital, or a 3. The battery life will depend on how you use it, with around nine hours of playtime via Bluetooth, 10 hours through the coax connection, and 25 hours if utilized purely as an amp.
But all this versatility comes at a notably higher price than our other picks. Lauren worked with Wirecutter senior staff writer Brent Butterworth to develop and perform the testing for this guide. Since , Brent has conducted more blind-listening tests than any other audio journalist in North America and probably the whole world while evaluating a few thousand speakers, amplifiers, and other types of audio equipment.
He owns a full suite of lab measurement gear for testing audio products. Most headphones sold today do not need a standalone headphone amplifier; the amp built into your smartphone, computer, or music player should be able to power the headphones sufficiently. The exception might be headphones with a higher impedance which defines how much resistance the headphones have to the flow of current or a lower sensitivity which defines how loud the headphones play with a given amount of power.
You can read more about headphone impedance and sensitivity here. When we first decided to tackle this guide, we planned on aiming it at the budding audiophile who wanted to spend no more than a couple hundred dollars on a versatile headphone amp and USB digital-to-analog converter DAC combination device for desktop and mobile use.
Initially, we thought the combination of a DAC and amp would serve to both power hard-to-drive headphones and improve sound quality. Can you taste the difference between muffins from each batch? Maybe, but man is it small. Also, there are a lot more important factors involved in whether a muffin tastes good. Foremost among them is the choice in headphones. Also, before you buy more gear to get better sound quality, consider the source: your music.
It will still sound off. And these days most phones and laptops have enough power to drive the majority of headphones without an additional headphone amp. The exception, as we mentioned above, are headphones with a high impedance or a low sensitivity, or headphones that use balanced armature drivers and have a sizable impedance swing see How we picked for more on this. There are a few DACs that look like an in-line cable with USB-C, but none of those were powerful enough for harder-to-drive headphones.
We also checked out audio fan forums like Head-Fi and AVS Forum to get a sense of what headphone enthusiasts were using. Last, we scanned the reviews on Amazon and Crutchfield to see if any problems consistently popped up in the comments.
This was the most complex testing process our audio team has conducted to date. We wondered how much of that was objectively measurable and how much was placebo or confirmation bias. We devised a testing plan that was as blind as possible so that we could take price, brand, and design out of the equation. To do this, we relied on Brent to come up with a game plan. The switcher contained only one component per audio channel: a relay of the same general type commonly used in many of the best power amplifiers and preamps.
All four computers ran the same software foobar and had the same digital music files AAC, MP3, and hi-res. They could listen to as many tracks as they needed to make a determination, the average being three to five tracks. These included a mix of AAC, MP3, and hi-res selections; in most cases the tracks were test files that the panelists supplied, chosen mostly from the tracks we commonly use to test headphones and speakers.
The proctor also had the option of including a standard laptop headphone jack without telling the panelist. We repeated this process until each panelist had heard all the contenders. At this point the panelist would pick favorites for that set of headphones. With each new pair of headphones, the proctor changed the groupings and the switch number assignments each time to avoid confirmation bias. In this final test we used AAC music files and iTunes as our playback software. If you want to hear what a 1 dB increase or decrease sounds like, try taking this blind test.
The DragonFly Red is about the size of a standard USB thumb drive, so it will pop right into your laptop bag or pocket without adding much bulk. Unlike bigger amps that have batteries, the Red is designed to be small enough to blend into your computer setup, so it can stay permanently plugged into your device without being cumbersome. Your machine will recognize the DragonFly Red immediately when you plug it in and give you the option of selecting it as your audio-output device.
Our expert panelists all loved the sound quality of the DragonFly Red. Our listening notes for the DragonFly Red consistently describe a little extra detail on the highs, a tad extra spaciousness and separation to the sonic depth of field, and a bit more precision in the handling of bass frequencies. The DragonFly has a single 3. In our measurements, we found that this amp could deliver a max output of 46 mW in headphones with an impedance of 32 ohms, 16 mW at ohms, and 7.
As mentioned in How we picked , for most listeners using most headphones, an output of 15 mW or greater is more than enough power for listening at a sufficiently loud volume level. The DragonFly Red has a low output impedance we measured 3. Our panelists experienced that effect firsthand when listening to the Shure SE headphones: A big impedance dip PDF makes these headphones vulnerable to coloration sounding too loud or quiet in certain frequency ranges , but the DragonFly Red drove them smoothly and clearly.
AudioQuest has a good reputation in the audiophile community and backs up the build of the DragonFly Red with a one-year warranty. The DragonFly Red has a few downsides. If you have very high-impedance headphones ohms or more , the DragonFly Red may not be able to give you the volume you crave again, we measured 7.
On the flip side, the DragonFly Red can be cranked too loud with ohm headphones. This means that when you have the volume cranked, the audio will sound distorted, sort of like a blown-out speaker.
However, for most folks without significant hearing loss, this volume level would be uncomfortably ear-splitting. If you turn the volume down about two notches, the distortion drops to almost nothing 0. That may not be a major concern with a computer or laptop, but the additional power draw is likely to cause your phone, tablet, or portable music player to lose battery life much more quickly than usual. For folks who utilize portable music players or phones as their audio source, we recommend the self-powering iFi Hip-dac.
And the smooth volume dial allows you to find your perfect loudness level. The one-year warranty will cover you should any early technical difficulties arise, but you need to buy an adapter cable for your particular mobile device. That said, you could certainly use it with a computer if you wanted to: The Hip-dac is plug-and-play for Mac and Linux devices, but Windows users will need to install firmware.
All of our panelists enjoyed listening via the Hip-dac. There is a perceptible improvement in detail when listening to planar magnetic headphones or tougher-to-drive headphones , though as with the DragonFly Red , the improvement is minor.
Similarly, bass notes are better defined, especially when listening at lower volumes. The Hip-dac has both a 3. Our measurements found it to be the most powerful amplifier of our three picks.
The Hip-dac had a maximum output of On the balanced output, we measured All measurements given at 0. Again, an output of 15 mW or greater into 32 ohms is more than enough power for listening at a sufficiently loud volume level.
With headphones or in-ear monitors that have impedance dips, the Hip-dac should drive them evenly, since the output impedance is pretty low: 0. Additionally, the Hip-dac offers a feature called Powermatch, which as far as we can tell seems to be an auto-adjusting gain setting.
The effect sounds like a milder version of a high-gain setting, which effectively increases the volume output for headphones that need a little extra oomph to power them. With low-sensitivity headphones, the Hip-dac can deliver adequate volume only when Powermatch is activated. In our tests, with a wide range of headphones, we could tell that the Hip-dac was optimizing itself to some degree, but we still needed to adjust the volume knob when we changed headphones.
Brent and I looked over the diagrams iFi provides on its website concerning how this works. But hey, the Hip-dac still does what it needs to, and does it well.
Old-school CD quality sounds excellent too. Like the DragonFly Red, the Hip-dac can distort when ohm headphones are turned up full blast. Another quibble is the lack of indicator dots on the volume knob. We appreciate sleek styling, but even small machined ridges would be helpful to avoid an uncomfortable blast of sound if the dial is accidentally set too high. For audio enthusiasts who need more diverse connection options, the self-powered FiiO Q5s provides a lot of versatility. Whether you want to link up to your music device wired or wirelessly, the Q5s can adapt to nearly every use case.
Like the AudioQuest DragonFly Red , the Q5s will power the vast majority of headphones up to ohms with ease, but it may not provide enough loudness with ohm headphones for folks who like to crank their tunes.
A bass boost button will instantly increase the presence of the low end—for headphones that need it or folks who are into that sort of thing. Our panel felt that most tougher-to-drive headphones were well supported, and with a very low output impedance 0. On its low-gain setting, it delivered But our high-gain measurements were better: Where the Q5s stands out is in its myriad connection options and wireless capabilities.
A single port can be toggled to accommodate optical digital, coaxial digital, and 3. For output, you can choose between a standard 3.
In addition to all the corded connections, the Q5s can be used wirelessly via Bluetooth 5. If anything goes wrong, FiiO covers the Q5s for one year under warranty. The physical volume dial on the Q5s adjusts loudness smoothly. We are confident that, as a headphone amp, the Q5s more than meets the needs of folks looking to drive their in-ear monitors or headphones effectively, but if you are looking for something to function as a DAC for other gear, you may want to check out what ASR has to say.
Most headphones are rated to deliver somewhere around dB from a 1 mW signal, which is pretty loud. We reached out to Audiolab to test the M-DAC Nano , but due to the global pandemic we were unable to get one shipped to us in time for this round. Once they are able to ship products again, we will test this one and update the guide with our thoughts.

If you're spending big on a pair of premium headphones , a dedicated headphone amplifier will make them sing much more than if you were to simply plug them into a computer, phone or even, depending on the quality of its built-in headphone amp, a hi-fi component. So what should you look for in a headphone amplifier? Analogue inputs mean you can plug in a traditional source, such as a CD player, but more modern amps boast digital inputs and a built-in DAC for broader compatibility — ideal if you're listening to music stored on a computer, say. Size and portability are also key considerations. Some of the below will happily slip into a jeans pocket and, with the right cables and connectors, can even be paired with a mobile phone. Other models command that you clear your desk.
