What is a Headphone Amp?
A headphone amp is a low powered amplifier that raises the voltage of the device you’re using. It brings it to a level that can be converted into sound ways to the speakers in your headphones. It works the same as an amp does for regular speakers. It’s just on a much smaller scale. This doesn’t mean that the sound won’t still pack a punch despite the amp being smaller than traditional speaker amps. Keep reading if you aren’t sure whether you should get an amp for your headphones and what you should look out for before buying.
Why Do I Need a Headphone Amp?
You need a headphone amp to allow your headphones to work properly and have enough power to be able to get a decent volume and explore their maximum potential.
Basically, if you have them plugged on your mobile and can’t hear much even at the maximum volume, this means you need an amplifier. Why does it happen? Because of the impedance.
If the impedance of your headphones is between 1 and 32 ohms, it will give them enough power to work. But If the impedance is between 33 and 100 ohms, it is a little tricky. Some models will be still working properly without an amplifier while some not. Basically, if you cannot hear them loud enough, it means that they are short of electrical impulses and so an external amp is necessary. For headphones above 100 ohms, you definitely need an amplifier.
*1 – 32 ohms: You do not need an amplifier.
*33 – 100 ohms: It would be better to use a portable amp to give them an extra boost.
*Over 100 ohms: You need an amplifier.
How to Use the Headphone Amp?
Using the best cheap headphone amps won’t require you to do anything at least anything on the technical side. That part is taken care of. All you have to do is plug it in for the most part. Each amp is specific in how it will work with your device. Most of them require you to plug it in through an output or input jack. If you are looking to use it with a phone or computer, the setup may be different. It could make you get an adaptor or work with a USB for the amp to function. It should be noted that some amps will let you change the bass or control the volume.
Do Cheap Headphone Amps Improve Sound Quality?
The short answer is both yes and no. Sound quality can improve but only with the right kind of headphones. If you have decent headphones and buy a higher quality amp, there’s a chance it will not only enhance the sound but let you make changes (i.e. bass boosting). However, if you have a low-quality pair, the sound isn’t going to improve by much if at all. Unfortunately, this goes for amps too. A low-quality amp (not to be confused with price) isn’t going to do much for your sound quality. Most amps will just make the sound louder and not enhance it, so if you have lower quality products it won’t make it better.

Since it’s USB, it can be used with almost anything. The ability to play various music files also makes it a selling point. One thing to note before buying is that sound quality will depend on your headphones. If they aren’t the best, it won’t enhance the sound. Keep in mind to use with other devices you’ll need an adaptor.
The Schiit SYS is a two-input passive preamp. You can control the volume yourself with the knob and can switch between DAC and a phono preamp. It’s versatile in the sense that it can be used with any line-level source. The components and designs are made in the US.
- Works with line-level sources
- Switch between DAC and phono preamp
- Can control the volume yourself

We like Fiio for a few reasons. It’s aesthetically pleasing to the eye while being durable. The battery life is super long, so you can listen all day for a long time. The sound quality is the best part. The bass is punchy, and the sound is clear and dynamic. But the only issue that makes us dislike to use it, is there’s a hissing/static noise when in use at any volume level. ***

It has EM interference shielding, Gain Switch, and Bass Boost to increase sound quality. It handles most headphones. The portability with the lightweight design and long battery life is an added plus. The only downside is the cable it comes with. It sometimes will produce static, so a 3rd party cable may be needed.
Things to Consider When Buying Best Headphone Amps under budget
1. Portable or Desktop Depends on Your Use
This will depend on your preferences and needs. There are many kinds of headphone amps you can purchase. The type you’ll want to buy will vary on what you need. Some important questions to ask yourself before purchasing an amp: Are you wanting portability from your headphone amp? Are you looking to use it for your computer or game console?
You’ll also want to take size into account. Portable ones are often small and can fit in your pocket. The sound quality won’t suffer based on the size chosen. The same goes for bigger ones designed for your desktop. Some smaller amps can even perform better than larger ones. Therefore, it’s imperative to know the type you’re wanting before you purchase.
2. Headphones Impedance
First, we start with the basics. Impedance is measured in ohms. It stands for the opposition to the flow of alternating current through a circuit.
Some headphones will need an amp to function properly. These are referred to as “high-impedance” headphones. The higher the impedance, the more resistance to an electrical signal. Headphones range from around 33 ohms to 600 ohms. Many of the headphones that come higher than 600 ohms often include their amps, depends.
In-ear headphones generally have smaller drivers in them requiring less voltage and work well with portable devices. Less voltage usually doesn’t need to have headphone amp and those with 33 ohms or higher should consider using a headphone amp for better sound.
Gain Switch options on headphones allow for a proper power match up of power being used and these are usually more flexible with all types of headphones.
3. What’s DAC
DAC (digital-to-analog convertor) converts digital audio information to a low-voltage signal that amplifiers can amplify. DACs are common among most headphones today. Turntables or tape decks don’t require a DAC since they put out analog low-voltage signals. However, computers, phones, and other digital audio devices need both the best headphone amps and a DAC so you can hear the sound.
Our top pick for the “best headphone amps under budget” goes to AudioQuest DragonFly Portable Headphone Amp. The overall design is unique in that it’s a USB compared to the other brands that are more like mini stereos in size or are powered by a battery. It has compatibility across other devices with an adaptor and can play various music files. The sound quality is amazing for the price. The only major hang up you’ll run into is if you have lower quality headphones. The sound might not be the best, so you might have to invest in a better pair.
