Best Cheap Headphone Amp Under $100 (Year 2018)

Modern headphones are designed to get the very best of audio performance from your music player or smartphone and are thus tailored towards the demands that MP3 playback involves and will improve performance more than a conventional pair of headphones.

Headphone amplifiers are not something that is found so commonly in most gadget stores. They are made especially for music enthusiasts, who are willing to invest in high-quality music.

They are small audio amplifiers, designed for headphones and not speakers that allow for higher volumes, better current capacity, high input impedance, low output impedance, and a greater range of output voltages. 

Generally, headphones amplifiers are found embedded in electronic devices that have a headphones jack, like integrated amps, TVs, and portable music players. 

There are a number of headphone amplifiers available on the market today:

  • check
    Studio Headphone Amps: These were the first ever headphone amplifiers to come on the market. They are typically combined with studio headphones and are AC powered. Some also run on batteries.
  • check
    Tube Headphone Amps: Tube headphone amplifiers use one or more vacuum tubes to improve the signal. Due to their unusual design, they are quite popular.
  • check
    Portable headphone amps: These headphone amplifiers are powered by batteries and best suited for traveling.
  • check
    Desktop Headphone Amplifiers: while the name may suggest computer use, these headphone amps can be used with home theater systems, stereo systems, and also computers.

Headphone Amplifier Buying Guide

When buying a headphone amplifier, you will need to pay special attention to the following factors:

What is Headphone Impedance?

Headphone impedance figures are generally provided in the user manual or on the packaging of the headphones.

There should also be a conforming figure for an amp as well as and both these figures are listed in a value of ohms.

The best way to find a pairing on the basis of impedance is to pair a headphone that comes with at least 10 times the ohm value of the amp being used.

For instance, a 3000-ohm headphone would pair best with a 30-ohm amp.

How Will You Use The Headphone Amplifier?

It is important to consider how you intend on using the amplifier; if you need something that will be best for listening on-the-go, or if you want something that will add to fixed desktop arrangement. For on-the-go listening, portable amps are the way to go and for a desktop setup, desktop headphones amps work best.

Do You Want A Headphone Amp Only, Or An Amp Combined With A Digital-To-Analogue Convertor?

Headphone amps are only responsible for processing analog audio signals, but in today’s advanced technological era, streaming services and digital music, there is another important component in audio setups, known as DAC or digital to analog converter.

DACs are responsible for taking a digital music file and convert it into an analog music signal.

Just like with amps, the DAC quality in non-audio specific devices such as PCs, laptops, tablets, phones, is a low priority for producers. 

For this reason, it is best to pair headphone amps with dedicated, quality DAC chips to provide a full audio processing solution for enhanced sound quality.

Other important factors to consider

What is Digital Sound Processing (DSP)?

DSP allows headphone amps to deliver a surround sound experience using only standard headphones. An example of DSP is Dolby headphone format. DSP allows for the signal to be improved and modified.

How many Number of Channels does it Offer?

Another thing to look for in a headphone amplifier is the number of channels it offers.

Headphone amps typically come with 1 to 8 channels. More channels are better as they deliver multiple signal distribution options for keeping the flexibility in check.

Every channel arranges individual stereo line distribution in a one-rack package.

What is the Signal-to-Noise Rating?

The signal-to-noise rating is a measurement of the headphone amp’s noise in comparison with its original source, which is measured in decibels.

The higher the ratio, the less noise compared to the signal. This is to keep that strange noise you have to bear when listening to your favorite music, a sort of white noise.

An optimal signal to noise rating means you will not have to worry about this little annoyance anymore.

What is Root-mean-squared (RMS) Power?

The Root-mean-squared power is the extent of real power that is delivered to the load. The amount shows how loud the headphones will get at their peak.

Loudspeaker Amplifier/Pre-Amplifier

This factor allows for the headphone amps to multifunction as either a loud amplifier or a pre-amplifier.  A pre-amp readies a small amount of electrical signal for additional processing or amplification and decreases interruption. While offering the headphone amp added flexibility, this option is also rather expensive.

How to choose?

A basic amplifier simply substantiates the strength of audio from the source and that alone fills in the gaps. However, exemplary headphones generate a precise reproduction, making the most of the audio they receive. Here we will be looking at the best headphone amplifiers under $100. You can expect these sets to offer the following:

  • Small size – A lot of the headphones amplifiers under $100 are small and thus, extremely portable. They can be clipped easily wound.
  • Audio amplification – If you own a pair of headphones that are not as loud or powerful-sounding as you would like them to be then a headphone amp can make your life easier. However, it is important to keep in mind that bad audio quality will not be miraculously transformed because headphone amps will function to improve the sound. So, if your headphones are really bad, you can’t expect a lot from an amp.
  • Decrease distortion– A lot of headphones get sibilant at high volumes, which is why headphone amps with an SNR are important to thoroughly reduce the distortion and give you a crispy clear audio output. This quality is best tested at loud volumes since normal volumes are generally protected from alteration in headphones too.
  • Impedance– These under $100 headphones support a wide array of headphone impedance. This particular factor is crucial in deciding which set of headphones these amplifiers can drive. Broader the range, the greater number of headphones these amplifiers can boost.
