What is a Headphone Amplifier?

It is similar to a normal amplifier for speakers but smaller in size. These are small devices that handle the signal from your music player and increase both the volume and the detail and the quality of the sound coming out of your headphones. Most are shaped like a small box .

They are designed to connect between your headphones and the source device (PC, MAC, TV, smartphone, game console, tablet). You just have to connect your headphones to the headphone amplifier and then it to the computer or music player.

This way the signal is amplified before reaching your ears and as a result, you get a warmer, richer and more powerful sound.

If you want to curl the curl and further improve the audio quality you can also introduce an external DAC to the scheme.

But this is already very pro-level. If you are interested in the subject we recommend that you take a look at our comparison with the best DACs in the market

Key Features:

  • 32-bit ESS 9010 Sabre DAC
  • Offering tremendously enhanced sound, higher value, and significantly lower power consumption than the original award-winning DragonFly
  • Works with Apple and Android phones and tablets when paired with a simple adapter
  • This versatile DAC improves everything detail, transparency, immediacy, richness, tone associated with your music

The Dragonfly v1.5 Red comes with a double output of 2.1 volts, while the Black is designed with an output of 1.2 volts. Well, after listening to both, I can confirm there are differences between the Black and Red versions. However, I see no reason to pay an extra $100 for the Red one just because of the minor differences.

To improve the overall performance of the new DragonFly models, Both the Red and Black incorporate an upgraded 32-bit ESS Sabre DAC chip and specifically the 9010 in Black.

I found the DragonFly Black having more of a neutral sound signature. The bass is tight while the mid-range is leveled and the treble is easy-going and presents enough details.

It must be said that the Creative Sound Blaster E3 does not belong to the hi-end category; however, it performs the amplification function perfectly. In addition to the amplification, the sound card slightly processes the outgoing tracks, adding a few low frequencies and slightly cropping the averages.

At the same time, the sound palette remains flat, without distortion at the bottom. In any case, the sound quality does not depend on the Sound Blaster E3, but on the headphones that you use. Still, the main function of Sound Blaster E3 is to amplify the audio signal, and not to improve it.

It is also important to mention that as soon as you plug the cable into the line input of the Sound Blaster E3, Bluetooth switches off and vice versa.

Topping NX2S Ultra Slim HiFi DAC Headphone Amplifier

Topping NX2S Ultra Slim HiFi DAC Headphone Amplifier

Buy-Now-amazon

If you look at the images, you can easily say that it’s very slim for a Headphone Amp that works also as a DAC having a length of 11cm which doesn’t make it entirely portable.

The reason why we’ve included it in our list of Best Headphone Amp Under 100 Dollars is that:

  • Retains an Industrial Grade Headphone Amp Design
  • Provides Total Harmonic Distortion of 0.0001% at 32 Ohms
  • Provides Battery life of 100 hours with built-in 1000 mAh battery
  • The battery is what increases its size.

As you can see, Topping NX2 isn’t the best looking Headphone Amp out there because it retains that industrial design which gives it a professional look.

The big question:

How much Headphone Impedance does it supports?

Up to 300 Ohms; which is an ideal choice unless you’re going for Beyerdynamic DT880 Premium.

Bravo Audio V2 Class A 12AU7  Headphone Amplifier

Bravo Audio V2 Class A 12AU7 Tube

Buy-Now-amazon

The Bravo Audio V2 comes in an open design with two transparent acrylic plates on top and bottom of this tube amp. The top plate has three cutouts, one for the tube and the other one for the large capacitor that sticks out on top. I am not a fan of the open design of this tube.

The Bravo Audio V2 does get hotter, especially the heat sink that can pose safety risks. For this reason, try as much not to move it while in operation and do not touch the heat sinks!

It is somehow designed to handle headphones that are difficult to drive such as the DT-990 (600 ohms) or the Sennheiser HD650 at 250 ohms. For low impedance headphones, the Bravo Audio V2 will still work, but you will have to be careful to avoid excessive volume levels.

Key Features:

  • Quality Promise-NX2s has CE, FCC and RoHS certification and exceeds the requirements of Hi-Res Audio.
  • NX2s uses OP(OPA1652)+BUF(LMH6643)structure to increase output power to 140mW x2(32Ω)maximum power, suitable for all kinds of headphones.

How to Choose a Good Headphone Amplifier?

What budget do you have? The first question you should ask yourself. Logically if you have not bought a cheap headset because you want quality you will surely also have the money available for an amplifier, although this resource is always limited. Luckily for you, there are many models of good quality and price like the ones we have listed at the beginning of the article.

Do you need a portable headphone amplifier Or a desktop? As you can see there is an interesting headphone amplifier that fits in your pocket as well as being the king for a good listening experience (the first model). Otherwise, if what you want is to use it basically on the PC, Mac or playing you will need a desktop.

The type of headphones you use. Closed, open or semi? If you have seen our comparison of DJ helmets (linked in the first paragraph) you will see that the open ones are the best for mixes and need some more thrust with an amplifier than those that are closed.

Type of music you listen to As a last point, this does not make a difference compared to the others, but we have also found it interesting to consider them. But think that if you listen to classical music if you buy a headphone amplifier that is fine by the bass, it is somewhat unrealistic. And on the contrary also, of course.

Why do you need it?

The headphones are small speakers that go inside your ears, so they require amplification to make you hear the original signals.

Now, when you connect them to your PC, desktop or your mobile, an additional amplifier is not necessary because these devices already contain them, but these have very little power and are unable to play your music at high-quality levels.

That’s why it’s better to buy a separate amplifier. When you use one of these devices, which are usually box-shaped and use valves, tubes or some other form of analog amplification, you will notice better results at higher volumes.

In fact, even at normal volumes, you will notice a more round, complete, warm audio, with deeper bass and clear and bright treble.

Now, if you have noise-canceling helmets, you probably won’t need an amplifier. For the rest, you will always benefit greatly from one of these devices.

Types of Headphone Amplifiers

There are three main types of headphone amplifiers for home use:

-Digital to analog converters (DAC),

-The amplifiers for desktop headphones and

-The portable hearing aid amplifiers.

Next, we will outline the main specifications of each of these types.

Digital to analog converters (DAC) :

Because most headphones are built for analog signals, you can use a digital to analog converter, to enjoy using digital headphones, the digital audio files stored on your computer.

However, you should know that computers usually have an integrated DAC, but most provide inadequate sound quality for audiophiles.

In short, in addition to format conversion, the DAC comes to provide an interface between the computer and the headphones, with the intention of providing a better translation of the audio files.

Amplifiers for desktop headphones:

You might think that a desktop headphone amplifier only involves the use of computers, such as DACs; However, these types of amplifiers can be used with stereo systems, home theater systems known as a home theater.

Desktop headphone amplifiers are used to boost and cancel out headphones with excess noise, and are essential for superior sound quality at home, recording studio, with your desktops, etc.

Portable headphone amplifiers:

Most media players, such as iPods, iPhone devices, and laptops do not have enough output power to provide better sound quality.

In these cases, a headphone amplifier for portable equipment can increase the signal of the headphones, providing a more adequate sound when a person is on the move.

Variables of a Headphone Amplifier

Along with the type of hearing aid amplifier, there are other features and variables that you should consider before buying such equipment.

In the following points, we present some of the improved features that a headphone amplifier can include.

  • Digital sound processing: Digital sound processing (DSP) allows headphone amplifiers to generate a surround sound experience even using standard headphones. An example of DSP is the Dolby headphone format, which in a nutshell allows you to modify and improve the signal.
  • The number of channels: Another consideration that you should consider when looking at headphone amplifiers is the number of channels offered by the amplifier. These generally come with one to eight, the more channels you have incorporated, this equipment, the more signal distribution and monitoring flexibility options you will have. In addition, as this system is usually found in the package of the same rack, it facilitates the organization and distribution of the stereo line independently.
  • Speaker Preamplifier / Amplifier: This variable allows the headphone amplifier to also function as a preamp for your speakers. A preamp comes to prepare a small electrical signal for the increase or processing of the signal, in addition in the transfer process, the interference is reduced. As it is a professional presence, it will give you greater flexibility than a headphone amplifier. Of course, you should know that this option will also result in a higher price.
  • RMS Power: The RMS Root Mean Square power (average square root,) is the amount of actual power that is supplied to the load. This measure indicates how high the decibel peak of the hearing aids will be.
  • Signal to Noise Ratio: The signal-to-noise ratio is a measure corresponding to the noise of the headphone amplifier compared to the source signal, measured in decibels. The higher a ratio, the less noise there will be in the signal. The noise is easily detectable in the headphones because they are so close to the ears, so this relationship is a really important factor when you choose a headphone amplifier.

Conclusion

Roughly I think it is clear what an amp is (as the English say) and what it works for. In addition to that, we have listed the best models at the best prices we have found online.

To say that we have ordered the models according to which we liked the most. Even so, as happens to us from time to time, we have not been able to say that one was better than another, more than anything because each AMP has something that the others don’t. Either power, design or being thought to be desktop or portable.

So, the best as per your need and budget.
