Headphone Amp Buying Advice

Before you start shopping for a headphone amp, it is important to ask yourself some questions and think about what will be your primary use of the device.

Headphone Amp Buying Advice


Headphone amps are designed to increase the power of a headphone by around 30db. A low impedance (under 60 Ohms) can be easily found on most devices, but high impedance headphones (>120 Ohms) require an amp with a higher gain switch and impedance matching capabilities in order to deliver its full performance.

The good news is that most modern headphone amps have gain switches that switch between different impedance ratings, so purchasing the right amp is not as difficult as it may seem.

What Is Headphone Impedance?


The most common way of connecting a headphone amp to your source device is via a 3.5mm jack. However, headphone amps also come with built-in USB ports, which makes it possible to charge your smartphone while listening to music on the go.

A headphone amp can also be connected via an RCA input or a speaker headphone output if you wish to upgrade your home stereo amplifier system as well.

Source device connections

The most common type of source device is a smartphone because it offers all the required features and functions in one device; however, it is also possible to connect the amp to your laptop or any other device that has a 3.5mm jack.


Digital-to-analog converters (DAC) are responsible for converting digital audio files into analog signals that can be reproduced by speakers and headphones. A good headphone amp needs to come with a digital to analog converter in order for the audio to be played back at its best.

Output Connections

Headphone amps come with one, two, or more output ports depending on the model and make. On most models, you will find dual headphone/RCA outputs which means that you can connect the amp to your home stereo amplifier system or powered speakers.

Build Quality

It is important to only invest in a headphone amp that has been built with high-quality components which will ensure durability and reliability over an extended period of time. The build material needs to be strong enough to withstand falls, rough handling, and the occasional rain shower!


A headphone amp that is not portable will only be useful if you are looking to upgrade your home sound system. If you want something for the outdoors, a good headphone amp needs to be lightweight and compact enough to fit in a small bag or purse.

Size & Weight

The size of the model plays an important role when it comes to portability. Miniature headphone amps are great for outdoor use, but they will not be very useful when it comes to home stereo system upgrades as you would need an amp with a larger capacity.

Headphone Amp Types

Headphone Amp Types (1)

Tube Amplifiers

Tube amps are some of the most expensive headphone amps on the market, but they also offer high-end good sound quality. The tube headphone amplifier is not very common in the portable audio world and even though you may find them as part of a home stereo system or an old car stereo system, their adaptability is limited to devices that have a 3.5mm input port.

11. Bravo Audio V2 Class A 12AU7

Tube headphone amplifiers are a long-standing favorite of many, and many still prefer them to solid-state amps. Tube amps can be expensive to purchase and maintain, as opposed to solid-state amps. The V2 Class A 12AU7 is a tube amp that anyone can use to get warmer tube sound.

It is an open-design tube amp with transparent acrylic plates at the top and bottom. Three cutouts are made on the full scale, one for the tube and the large capacitor. I wouldn’t say I like the tube’s open design.

This device gets hotter, particularly the heat sink, which can pose safety hazards. It is essential to keep the device in place and not move it.

It features a 3.5mm minijack input port and a Japanese ALPS volume knob. A 6.3mm headphone port is also included on the front.

The side also has RCA inputs. On the back of the V2, you will find an on/off toggle switch as well as a connection port for the wall-wart. The amp feels durable in most parts, but the volume knob can be sensitive when adjusting the volume.

It can handle headphones with complex drivers such as the DT-990 (680 ohms) and the Sennheiser HD650 (220 ohms). The Bravo Audio V2 can still be used for low impedance headphones. However, it would help if you were careful not to exceed the volume limit.

As I mentioned earlier, the volume knob on the Bravo Audio V2 can be very sensitive, and even the most minor adjustments can result in a higher volume.

You can roll the tube to improve the sound and personalize the amp to your liking. It is also available in V2+ Upgrade models. The only difference between these amps is the tubes. Bravo Audio V2+ Upgrade uses the Golden Lion ECC82 tube.

This review was conducted without modifications to the Bravo Audio V2. Let’s see how it sounds.

First, high-sensitivity headphones don’t need the amp. Otherwise, there will be distortion. This device increases the volume in the lower end and midrange. Vocals and instruments such as guitars are heard, with the treble slightly underemphasized. It is the best headphone amp for you.


  • Performance excellence
  • A warmer sound
  • Good synergy


  • The stock tube is useless.

12. FX Audio DAC-X6 Best Headphone Amps

FX Audio DACX6 is one of the very best headphone amps under 100. The model was first seen in Aliexpress before it became available on Amazon. After reading many reviews on the product, I decided that I would give it a try when it was available on Amazon.

The FX Audio DAC X6 is exceptionally solidly constructed and uses high-quality materials that last longer. You can choose from two different colors for the FX Audio DAC X6: black or silver. The black model was what I decided. The metal casing adds strength to the FX Audio DACX6.

The FX Audio DAC X6’s front panel features a power switch and a three-stage switch that allows you to select fiber, coaxial, or USB. It also has a 6.3 mm connector for headphones and a volume knob.

The back panel houses the USB input and optical inputs as well as two RSC inputs. It offers many input options. It has a USB, optical coaxial. I also love that it is not USB-powered.

Three headphones were used to test the power of the DAC/headphone amplifier headphone. They were the HiFiMan HE400i and Audio Technica ATH–AD 700X.

The Sennheiser HD650 was also used. Surprisingly, this device is powerful enough to drive the HD650, a high-power headphone.

It also gave out more power to my ATHAD700X, which I mainly use for gaming. The amp significantly improved the soundstage, particularly in FPS games that use positional sounds.

Overall, this device was a better headphone amp than a DAC for me. The headphone’s sound output is also much better than the better sound from the computer. This amp runs on AC power but has very little background noise when music is played.

When you pause music, however, you will hear a hissing sound. This is especially true if the volume has been increased to its maximum. The noise level is shallow, and I don’t notice any reduction in audio quality.

This amp’s sound is loud and clear. I used headphones to test it. Also, the clarity and soundstage were significantly improved. However, I didn’t use the RCA or coax inputs; all other information was performed as expected. If you are searching for the best headphone amp, let’s check out it.


  • Different input ports.


  • A slight hiss at higher volumes.

13. Top NX1s

The amp will deliver far more than its price for a headphone amp such as the Topping NX1s, just $50. This amp is affordable enough to be affordable by almost anyone. It’s also compact and portable, so it works well with smartphones. It is probably the very best headphone amp.

Topping NX1s has a slightly different design than the previous models of this headphone amplifier. Topping NX1s has a unique front panel design.

It is also smaller in size than its predecessors. The amp’s build quality is excellent, and the aluminum casing makes it lighter than its predecessors.

On the front panel is a headphone port and an input port. Both ports are 3.5mm. The projection partially covers the volume knob.

It has a great feel and is a very good potentiometer. The back panel houses the micro USB port to charge and two switches for bass boost and gain.

Topping NX1s are said to provide up to 40 hours of audio playback. This is an excellent range for a portable headphone amplifier. The amp ran for almost three weeks on one charge after being used only for a few hours per day.

The amp has enough power to drive low impedance headphones like the Sennheiser 558s at 50 Ohms. It was good to test it with a higher impedance headphone such as the HD650, but not as powerful as expected. Overall, I recommend this power amplifier for IEMs or portable headphones.

Full settings, max gain, max boost, and total volume were sufficient to hear no distortion on both the HD-650 and 558s. The HD-650 has a low volume.

The sound quality is clear and transparent, with the bass boost adding an extra kick to the low notes. You can hear the difference in audio quality when you adjust the high gain. It is seen as one of the best headphone amps under 100.


  • Long battery life, sturdy construction, and low prices


  • Not enough volume with high impedance headphones

FiiO headphone amps under 100 is a top-tier industry player that has worked hard to provide the best and most affordable audio gear. It can be challenging to know what equipment is required if you’re a novice in the field of HIFI equipment.

You could also end up spending a lot on unnecessary gear. FiiO is a great brand that offers entry-level gear. The FiiO Q1 is just one example.

The FiiO Q1 is a hip flask-like amp that resembles the FiiO E11K, now renamed the FiiO E3. The amp is well-built with a metal casing. The only part of the FiiO Q1 that I noticed was plastic at the top, which partially covered the volume knob.

Overall, I love the amp’s design but would prefer it to be flat on either the top or bottom to make stacking easier with other devices more accessible. The front panel of FiiO Q1 has a bass boost switch and a partially covered volume knob.

There is also a 3.5mm headphone jack. The amp’s back panel has a 3.5mm input port, while a gain switch is next. A micro USB port can be used for charging.

A controller controls the USB charging. It is located to the right of the amp. The switches on the FiiOQ1 are well-strung and easy to use. An LED light on the front of the lamp lights up in blue when used, green when it is fully charged, and red/blue if it’s charging.

FiiO Q1 headphone amps under 100 include a 1400mAh LiPo battery which is capable of powering the amp for up 30 hours. The amp can play music for 30 hours, but it will vary depending on its use and settings. My tests showed that the time was very accurate. The best part is that it takes less than 4 hours to recharge to full.
