Best Headphones Amplifier 2017 – Reviews & Buyer’s Guide

Equipped with considerably more output to power your headphone, a headphone amplifier will provide an enhanced listening experience to your music.

The intention is not for the music to become louder, but for it to sound cleaner and more controlled than it is able to normally, especially during peaks.

Though, the amplifier can also make it louder if you so wish. This means certain elements in the track that your smartphone doesn’t pick up on as well as your laptop for example, can be enhanced.

This also means that if you have a poor volume supply and control from both the headphone or device, then you can rectify this through the headphone amplifier.

Let’s take a look at some of the best options:

Why do I need a headphone amp?

How to choose the best headphone amplifiers?

Headphone amplifiers come in a range of different styles and designs, with some in the form of a USB you can take anywhere, and others being much heavier and more suited to home studio use.

Depending on your headphones, you will need a model capable of working with the different impedance ratings, so it’s good to check the stats of each model against the headphones you intend to use them with.

Also, you will find headphones amps tend to have lots of other features to enhance not only the music (such as gain control) but also other handy tools to work with your other devices too, such as being able to charge your phone from then.

The model you choose really depends on your requirements as user, but also the quality and type of headphones that you use.

The advantages of headphone amplifiers

When you plug your headphones into your smartphone, there is limited volume, power and sound enhancement options, that may limit the sound quality you actually receive.

How limited depends on the impedance rating all headphones have. Regular headphones designed for use with smartphones typically have a lower impedance rating, however audiophile quality headphones have a much higher impedance rating.

Without a headphone amplifier, you will lose significant volume and overall sound quality especially if listening through professional, audiophile quality headphones.

Another advantage is that if you struggle with your hearing generally, then an amplifier has the potential to help you hear certain ranges that you would normally struggle with, given its whole purpose is to drastically increase the overall output.

Though it should be said that no matter what you hearing ability, a headphones amplifier has the potential to completely transform your listening experience for the better.

Though it is small and compact compared to most headphone amplifiers, an obvious downside with the USB aspect means that is it’s not going to be compatible with smartphone use, rather laptops and pcs. This means unless you buy a separate adapter cable, you won’t have the full range of usage compared with models that attach straight onto your headphones.

All in all though, this is a minor issue that can be overcome if you simply buy an extra cable so in the grand scheme of things, if you are serious about upping your audio quality this would be an excellent model to choose, as it gives an outstanding enhancement to your music and is packed full of features that would delight any audiophile.

​Magni 2 Headphone Amplifier

Design

Battery

Summary: The Magni 2 is a model built with every headphone in mind, due to its switchable gain which provides the low noise floor you need for sensitive headphones, as well as the power for hard-to-drive high-impedance headphones and orthos.

As a result, the sound produced is World class. The Magni 2, unlike so many similar models have fully-discrete amps, and uses a new gain stage with non-stop feedback across the entire audio band.

Though excellent in terms of audio performance, a possible disadvantage with this model is its bulky size weighing in at one pound. This means it’s not going to be the most convenient thing to carry around with you, especially on the go. So, with the Magni, it is probably better suited to home studio use.
