This dedicated headphone amplifier comes in a neat little rectangular housing that only takes up about 50 square inches on your desk. This enclosure has a well-designed metal frame that gives off a premium look; despite being cheaper and more lightweight.

The headphone amp enclosure is not the most compact (taking up almost 50 square inches), but I’m sure you’ll be able to make some space for it on your desk. Besides, the device is rectangular and stackable.

The front panel is minimal and straightforward. It includes a volume control knob and a 1/4″ headphone jack. Everything else is on the back panel and offers a power switch, gain switch, and RCA input and output ports.

Unfortunately, the headphone amp doesn’t make room for a built-in DAC (as you can see from the lack of digital ports); hence, you might need to spend extra on a separate DAC — preferably a Schiit Modi.

The Schiit Magni Heresy dedicated headphone amp supports a wide range of headphone impedances, so you’ll have no problem plugging in a pair of SHURE SE846s or Sennheiser HD600s. (Take note: IEMs will have lots of distortion at high gain.)

Specs

• Dimensions: 2.44″x0.74″x0.47″
• Weight: 0.46lbs
• Max Power: Unspecified
• Output Impedance: 0.65Ω
• I/O: USB in, 3.5mm out
• Built-in DAC: Yes

Also, making it onto our list of the best headphone amps under $500 is the handy AudioQuest Dragonfly Cobalt headphone amplifier; the device is only the size of a thumb drive yet manages to stay ahead of many other amplifiers in the market, regardless of size.

Similar to a flash drive, this headphone amp uses a USB Type-A interface to connect to your source devices. Its ideal use case is for laptops, but you can also make do with desktops and smartphones (provided you purchase the “dragon tail” USB adapters).

Even though AudioQuest does not specify a direct headphone impedance rating, these headphone amplifiers, especially the high-end “Cobalt” headphone amp, can drive headphones in the 16-100Ω range seamlessly. It might be a bit harder for higher impedances, but thankfully, it will keep things audible.

Specs

• Dimensions: 6.77″x2.63″x1.06″
• Weight: 1.54lbs
• Max Power: 950mW @ 32Ω
• Output Impedance: <1Ω
• I/O: Coax in, USB in, 3.5mm out, 1/4″ out, RCA out
• Built-in DAC: Yes

Featured in our list of the best DAC amp combos, the iFi Micro iDSD Signature is an absolute beast of a solid-state headphone amp. The device has a sturdy rectangular enclosure which is small enough to carry in a pocket but large enough to accommodate high-quality electronics that can drive most power-hungry headphones.

Thanks to its rechargeable battery, this headphone amp can deliver balanced sound at a maximum power of 4,000mW for 6-12 hours (depending on the power requirements of your headphones).

However, if you’re not so keen on relying on the battery alone, you can also keep it plugged into a phone charger via USB-C and power the amplifiers directly. It doesn’t matter which method you use; the passthrough feature ensures you get clear, interference-free audio.

This headphone amp has a ton of built-in controls ranging from a simple volume control knob at the front to switches that toggle the:

• XBass+
• 3D+
• iEMatch
• Filter (for the DAC) and
• Power Modes

Hence, this headphone amp offers a lot of flexibility, and these are not just for show because when coupled with the built-in DAC, you’ll get a stable and neutral analog signal that can power through your headphone’s impedance.

Specs

• Dimensions: 3.26″x2.44″x0.9″
• Weight: 0.4lbs
• Max Power: 600mW @ 32Ω
• Output Impedance: 0.06Ω
• I/O: Micro-USB in, coax in, Optical in, 2×3.5mm outs
• Built-in DAC: Yes

First off, let’s get to the obvious stuff: the aesthetics. Despite looking like a cheap piece of plastic, the enclosure has a durable aluminum finish. This sturdy exterior is snug and keeps everything from falling apart, even when carrying it around your jeans pockets.

And yes, the Chord Mojo 2 can safely fit inside most pockets since it is only 3.2 inches long and 2.5 inches wide — with less than an inch of depth.

Regarding the I/O panel, I wouldn’t call it a “straightforward set up” due to the two 3.5mm ports on the left side, with a coax, optical, USB-C, and two Micro-USB ports on the right.

One of these Micro-USB interfaces is for charging the battery, while the other (along with the rest of the ports) ports cater to the digital and analog I/Os.

Despite the micro-USB interface, the battery is an impressive component as it allows this headphone amp to run non-stop for almost eight hours.

The four buttons manage functions such as switching the amplifier on and off, controlling volume, and navigating the menu (the menu includes a host of built-in functions such as tone control adjustment, mute, crossfeed, and button-lock).

The sound quality on this device is exceptional as it provides an organic output free from distortion or filters. Overall, the Chord Electronics Mojo 2 is another premium device that can seamlessly switch between a desktop amp and a portable headphone amplifier.

Specs

• Dimensions: 4.29″x2.32″x0.51″
• Weight: 0.245lbs
• Max Power: 370mW @ 32Ω
• Output Impedance: 1.2Ω
• I/O: USB-C input, 4.4mm, 2.5mm, and 3.5mm outputs
• Built-in DAC: Yes

So yes, the FiiO Q3 includes a USB-C interface for charging the battery and offers a ton of accessories such as:

• USB-C to USB-C adapter
• 3.5mm to 3.5mm TRS headphone jack
• USB-C to lightning adapter
• Silicone anti-slip mat
• Drawstring pouch
• Silicone straps

So there’s a lot of opportunity here for “on-the-go listening” with your mobile phone, laptop, iPad, or gaming console.

These accessories will all be for nothing if the headphone amp is too big to carry around your pocket. Thankfully, the people at FiiO have designed the housing with dimensions similar to that of a regular smartphone. (At just half an inch of thickness and diagonal body size of almost 4.5″.)

Apart from the form factor and the respectable battery life, the I/O panel on this setup is just as impressive. On the front, there’s a 3.5mm line in/line out port, and a 2.5mm and 4.4mm balanced TRS port, with the USB-C port on the rear panel.

The I/Os, specifically the 3.5mm two-way port, are handy. The reason is that the USB-C port cannot handle power and data simultaneously, so while it is recharging (or directly powering it through the USB-C interface), you can use the 3.5mm input port to still be able to drive wired headphones. (Do note, however, that this bypasses the internal DAC.)

The audio quality is satisfying, with a warmer bass, clear mids, and less intense highs. The entire frequency range is not flat nor neutral but reproduces good audio for most headphones; hence, casual users will have no problems.

Specs

• Dimensions: 1.73″x 3.11″x 3.11″
• Weight: 1.1lbs
• Max Power: Unspecified
• Output Impedance: 20-600Ω
• I/O: RCA in, 3.5mm in, 1/4″ out
• Built-in DAC: No

Tube amplification used to be a thing of the past solid-state headphone amps are slowly taking over. Regardless, if you’re still looking for an authentic tube amp experience at a fair price, the Bravo V2 has got you covered.

With the Brave V2, you can experience the “joys of the tube amp lifestyle,” which includes burning your fingers on the conductive housing, dealing with a messy control layout, and waiting half a minute before the tube amps fire up.

So as you’ve figured out by now, tube amps can get so “hot right now,” and the Brave V2 is no exception. Despite taking up a small amount of real estate (1.73″x3.11″), the acrylic casing and exposed heatsinks need more space to dissipate heat successfully. Therefore, it’s best to give it a wide berth and keep sensitive devices away from it, especially laptops and mobile phones.

Also, this is a strictly pure tube amp, meaning you will need external DAC and RCA cables to play music. (For which I recommend the inexpensive FiiO D3.)

About the audio quality: I have no complaints. However, there is a smidge of distortion because of the tube amplification characteristics of this device. It is a given with tube amps, so you won’t be able to get rid of it entirely. (That is if you manage to notice it.)

Specs

• Dimensions: 5.63″x5.47″x2.76″
• Weight: 0.66lbs
• Max Power: 1V @ 32Ω
• Output Impedance: Unspecified
• I/O: USB in, mic, headphone, and loudspeaker ports, each as 3.5mm TRS
• Built-in DAC: Yes

The exterior of the headphone amp features a neat little box with a capacitive touch screen and silver-colored volume dial. The I/Os are in the back and include a Micro-USB interface for connecting to your computer and 3.5mm TRS ports for the microphone, headphones, and powered speakers.

There are a lot of controls built into this gaming headphone amp, but unfortunately, I have mixed feelings about the setup. The silver volume dial and the centerfold capacitive touch buttons are great additions. However, the four buttons on the edges are very sensitive and will trigger every time you reach for the volume control knob — there’s no way to tone them down or disable them entirely.

There are four equalizers: default, gaming, music, and movies. Despite the variety, you’ll find yourself resorting to the default preset most often because the others are just pumped-up bass or an odd combination.

The sound quality of the default preset is surprisingly detailed and accurate. Along with the 7.1 surround sound option and a pair of open-back gaming headphones, you’ll have an airy and immersive soundstage more in tune for either casual or competitive scenarios. (Provided you figure out how to soundproof your case fans.)

Specs

• Dimensions: 14.0″x7.0″x4.0″
• Weight: 3.03lbs
• Max Power: 300mW @ 44Ω
• Output Impedance: Approx 0.01Ω
• I/O: XLR, RCA, and 3.5mm inputs, 1/4″ output
• Built-in DAC: No

Right out of the box, you might not be all that impressed with the aesthetics of this device, and that’s because the RNHP headphone amp is not about looks it’s about practicality. The headphone amp, outfitted with a sturdy steel enclosure, makes it durable and able to withstand the harsh realities of a rock-and-roll lifestyle.

Although the headphone amp doesn’t prioritize portability, it’s not just a big chunk of metal since it only weighs 3.03lbs, with the case being 14″ long and 7″ wide.

Also, despite lacking a built-in DAC, the controls and I/O on this headphone amp are built to serve a purpose. You’ve got the 1/4″ headphone output on the front with the volume control knob and three LED indicators/buttons for the input sources. At the rear panel, you’ve got a couple of balanced XLR connectors, an unbalanced RCA, and a 3.5mm TRS port for the inputs. So unlike other headphone amps, no fancy filters, bass boosters, or power modes.

The headphone amp has a frequency range of 10-120,000Hz, and unsurprisingly the audio amplification characteristics of this amplifier are top-notch. It isn’t the most premium or clear-sounding, but it is right up there with the best.
