Best Headphone Amp Under 100 – 2020 Reviews & Buyer Guide

 

Technically, a headphone amplifier is a modification device. It is a device that supplies more power to your existing amplifier to enhance the sound quality. It may make the sound louder, dynamic, and of course, richer.

Although you will find these already incorporated in your smartphone, tablet, laptop, MP3 player, or any other music device that you use, they are also available separately for the consumer market.

The latter means that these devices are also available for separate purchase and use for enthusiasts who wouldn’t compromise on sound quality, even if they’re listening to music to keep them from sleeping during boring work. You know what we mean.

But the point of dispute in the market is the price. Some companies market these tiny and generally low-powered devices (at least in comparison to speaker amplifiers) at unreasonably high prices. They go as far as demanding 20,000 dollars for one. Believe it or not, amps under 100$ are capable enough to provide a competent performance.

That is exactly why we bring this list of the best headphone amp under 100 to you. Trying these couldn’t hurt much. Right?

So, brace yourself! You’re about to meet your first or perhaps next best headphone amplifier! The phenomenal models below will cost you within 100 dollars.

Also, if you are starting from scratch, then scroll down. Below the top 10 headphone amp reviews, you will find a complete and comprehensive guide about how to choose the best headphone amplifiers. So, let’s get started!

It features a 3.5 mm jack. And has a resolution of 24bit/96kHz, which makes listening to HD tracks even more fun. The audio quality is better than that of a CD. Moreover, it comes with 64-position analog volume control. You can control this digitally through your computer or mobile.

Upon examination, you’ll notice a stylish volume dial on the right side where the lid was present in the previous model. On the left side, there are conventional balanced headphone outputs of 3.5mm and 2.5mm. Also, there is an in/out port, gain adjusting switch and a bass increasing switch. While this upgrade certainly makes room for other connectivity options, its large diameter makes it difficult to place it on the surface flatly.

How to Choose the Best Headphone Amp Under 100?

Most aspiring audiophiles are almost always hesitant when purchasing newer components for their audio systems. Having little knowledge of what would be the best, or what to look for, keeps them from pursuing their passion to its fullest.

If you find yourself fitting perfectly in the frame mentioned above, we would advise you to take a deep breath and embrace the sound-loving freak that lives inside of you. It is your domain, and this is where you should vibe unapologetically. So, say goodbye to hesitance!

Just spend a couple of hours researching the internet, and you shall know all that you need to know. Or better, spend two minutes, or so, reading the guide below, and you will know most of the stuff that you ought to, especially about the headphone amplifiers.

Things to Consider

The following are a few key specifications to consider when buying the best budget headphone amp:

Connections

Generally, there are two types of connections, both in terms of cables and jacks. Let’s have a look at the jack-options first:

  • 3.5 mm
  • 6.3 mm

Usually, you will find most headphones compatible with 3.5 mm. And hence, most portable and even the best desktop headphone amp offers a 3.5mm connection.

However, some headphones amplifiers do provide a 6.3mm jack for high-end headphones. But there’s no noticeable impact of these connections on sound quality. So, choose one based on convenience.

Second, let’s look at the cable connection difference. There are two types of cable options:

  • Balanced
  • Unbalanced

The balanced cables have three conductors. You will find these dedicated to positive, negative, and ground signals, respectively. On the contrary, unbalanced have only two conductors. One for positive and the other for the ground, which also serves for negative signals.

Needless to say, balanced performs well as it comes with dedicated conductors, which carry out their job efficiently. In the unbalanced cables, the ground one is unable to filter sound, leaving a bit of electrical hum in the background.

But then again, if you can’t spend on a balanced one, don’t fret yourself out. The difference exists, but it’s negligible.

Types based on Technology

The market currently has three popular types of technologies that manufacturers incorporate in headphone amplifiers. These are:

  • Solid-State Technology
  • Tube Technology
  • Hybrid Technology

While tube technology is older than solid-state, it is much less popular in portable headphone amps due to their sensitive nature. Although they deliver warmer and more pleasant sounds, they are susceptible to damage more than the solid-state ones. Plus, tube-tech is way much more expensive.

But solid-state tech isn’t a compromise either. This robust tech delivers sharp and clean sound at a reasonable price. The models featuring this tech will last longer. But may lack the warmth of certain tracks and sounds.

Hybrid technology in amplifiers fundamentally refers to a mix of the two-parent technologies mentioned above. With this, there’s both warmth and durability. But again, it may cost more.

Types based on Design

When considering amplifiers of all sorts, there are three types of amps based on design. These include:

  • Rackmount Amplifiers
  • Desktop Amplifiers
  •  Portable Amplifiers

Rackmount Amps feature more input options, and they best serve studio needs. As the name suggests, they require a separate rack or place for permanent placement. They are heavy, power about six pairs of headphones, and are difficult to carry.

Desktop amplifiers, on the other hand, can sit easily on your desk or desktop. They offer as many as four outputs to power 1 or 2 pairs of heavy or light headphones. They can even power studio monitors.

Portable amplifiers are perhaps the ones you seek. They are the smallest of all and can even fit in your pocket. They can power one pair of headphones and acquire power via battery or electrical charge.

Impedance & Wattage

Impedance, measured in ohms, refers to the resistance provided by the electrical circuit of the amplifier to the flow of current. You will find both low-impedance and high-impedance models in the list above.

But which one should you choose? Well, to determine that you need to have a look at the wattage specifications too. Fundamentally, wattage is the power generated by the amplifier, given in Watts.

Suppose that an amp has specs saying 32 ohms and 2 Watts. Now, this means that the amplifier is producing 2 Watts of power upon 32 ohms of resistance.

Generally, the impedance of the headphone amplifier ranges from 0.5-50 ohms. That classifies as a low impedance headphone amplifier, and they will best serve your needs, as they are capable of producing louder sounds. Although they consume more battery, they are highly likely to be compatible with your headphone specs.

Frequently Asked Questions

Can I use a stereo amplifier instead of a headphone amplifier?

To put it straight and honest, you better not. Why? Well, mostly because you’re on a budget buy here. Be it, headphone amp or stereo amp, you’re probably searching for something within your mid-range budget. And the term budget amp applies to amps costing $500 or more even. The premium models are huge investments.

With that said, only premium stereo or integrated amps can offer a high-quality headphone output, which compares to the output of a dedicated headphone amp. The models costing lower usually perform only the best in their specific functions. Such as the dedicated headphone amplifiers give their best for headphones while integrated stereo amps give their best for speakers.

What is a DAC?

DAC, a short for Digital Analogue Converter, is that magician in your playback device that converts all those and zeros into actual analog sound. Without it, digital sound information may never convert into analog signals. Hence, it’s one of the fundamentals of audio devices. Plus, it gives a cleaner sound and deeper soundstage.

Usually, almost all playback devices come equipped with their very own custom DACs. But in today’s world, almost all of us, along with diehard audiophiles, have developed quite an ornate and elaborate taste when it comes to music. The performance of company-installed DAC devices or chips does not seem to satisfy our demands. And hence, external or separate DACs have become common. You can get an additional one and boost your listening experience.

However, if you are purchasing any of the headphone amps listed above, you might not need to. That’s because most of them already come equipped with additional DAC.

Do headphone amps under 100 have fixed frequency response?

Frequency response technically refers to the range of audio frequencies that an amplifier is capable of reproducing. And that mainly depends on the technology used in the amplifier as well as its construction.

As you can see above, different amplifiers have different combos of quality and technology. Thus, there can’t be a fixed frequency response of all amplifiers under 100 dollars.

However, the frequency response fact that’s common in all is that they cannot provide a high-level frequency response of speaker amplifiers.

Final Words!

Summing up, let’s get one thing clear: shop once and shop wisely. Sure, purchasing an electronic device under a hundred dollars cannot harm much. If not anything, it will provide you with valuable experience. But why waste even one penny of your hard-earned money when you have better and safer alternatives?

For this very reason, give yourself a couple of hours before clicking on the add to cart button. Research thoroughly on what you need and what you want. Determine which of the two can your pocket cater to currently. And only then, pick your next best headphone amp under 100. With this approach, chances are you’ll settle for something that’s going to feel rewarding for a long, long time. Thus, saving resources and fueling your interest. Happy shopping!
