Do I Need A Headphone Amplifier?

What is a headphone amplifier?

Simply put, every device that allows you to plug in headphones has an amp built in. The amp takes the audio signal and boosts it, allowing us to hear sound through the headphones. Amps don’t only boost volume; they can add and improve qualities like soundstage and separation. Adding an amp to a setup can also bring extra warmth or clarity. This all depends on the quality of the amp and how it has been designed. The reality is that most people won’t need an external headphone amp. That’s not to say that they wouldn’t benefit from one, though. Smartphones are now a very common music source, and with the technology getting better and better, they do a decent job of delivering good quality sound to most portable headphones and earphones. There are plenty of headphones designed to be used with mobile phones and other low powered portable devices. These headphones generally have a low impedance of up to 32ohm, and high sensitivity of around 100db, so they are very easy to drive and are more likely to go louder. Remember though: not only do amps add extra power but they can also improve the quality of the sound. So, once you start looking at higher quality headphones, improving your amp will start to make more sense as you will want to get the most out of them. No matter how good your headphones are, the sound quality will be limited by how good the amp is.

How to choose a headphone amp

If you’ve decided to go for a headphone amp, you now need to decide which one to go for. There are many to choose from, and they go for anything between £20 to £2000 and more. Amps can be split into two main groups: portable and desktop. If you want to add some power to your phone or laptop, then you will want to look for a portable amp. These amps can be charged, and will run off batteries, making them ideal for using on the move. They are also small in size, and there are some out there (like the Shanling UP4) which can connect to the source wirelessly using Bluetooth.

If you only use your headphones at home, or intend to use headphones that are particularly hard to drive, then you will probably want to go for a desktop amp as they are generally more powerful. Not only are they more powerful, they also tend to have a larger amount of inputs and outputs, making them very versatile. They will need to be plugged it at all times, so will need a power socket to work. As amps can bring their own character to the overall sound quality, it’s worth making sure you choose wisely and pick an amp that will compliment your headphones. For example, if your headphones have a warm or bassy sound then it’s a good idea to go for a neutral or bright sounding amp. This also works the other way around; a warm sounding amp will complement bright headphones and help to balance the sound out.

Optoma NuForce uDAC5 Review

NuForce uDAC5 Mobile DAC/Amp Review

The Optoma Nuforce uDAC5 is an excellent little DAC/Amp that cannot be beaten in size or sound for the price. It is a solid unit with a slightly smooth sound that is sure to please.

Pros:

  • Size
  • Build
  • Sound

Cons:

  • None for the price

Aesthetics, Build Quality and Accessories

The Nuforce uDAC5 is a tiny little thing, that looks great with a clean metal housing and good sized volume knob. The casing is all metal with a LED light on the front indicating it is on, along with the volume knob and headphone socket, inputs and outputs on the back and that is it.

Built quality is excellent, with the all metal case and solid sockets this little thing is built to survive. The volume pot moves smoothly and everthing feels well put together, the finish of the case is impeccable.

Accessories are not really included, all you get is the DAC, USB cable and quick start guide. I would have like to have seen some rubber feet included, maybe a pair of RCA cables too. But most people already have interconnects so not a huge issue.

Ease of use and Features

The uDAC5 is simple and easy to use, with the latest Windows 10 update, it is plug and play with no need to install drivers. Otherwise the drivers are available from the Nuforce website, I had no issues getting the DAC to work and it just started playing music instantly.

The RCA outputs are controlled by the volume pot, and not a fixed line out. This means you can use this with active monitors, but if you are going into an external amp set the volume to 100%.

It can also be used to convert USB signal to a coaxial for use with an external DAC that has no USB input.

Sound Quality

First off I will say the headphone output has fairly high gain and can drive the Beyerdynamic DT990 600 Ohm with ease, it also worked well with less sensitive IEM’s but won’t be the best match with very sensitive IEM’s unless you lower the volume in windows.

Out of the headphone output the uDAC5 has excellent sound throughout the range, it is not bright and clinical yet still brings out the detail in music. It is a big step up from on board audio out of a PC/Laptop, the sound is sightly warm and euphoric with good separation. I do find the internal amp to be fine for casual listening with easy to drive headphones, but you will notice a difference when going to a full size desktop amp with harder to drive headphones.

Everything is well placed in the mix, the lows hit hard and dig deep, vocals have a sweetness to them that is quite pleasing and highs have good definition and extension, lacking only the micro detail and air that higher end equipment offers.

As a pure DAC the uDAC5 is clean and clear without any real flaws, it works really well in any system providing a big step up from on-board audio. I feel there is still a slight smoothness to the overall sound which does get rid of any potential harshness but can slightly hide some micro detail.

Conclusion

For the price the Nuforce uDAC5 is an excellent piece of kit, it would be perfect for a coffee shop setup, or a small office rig, it is also perfect as a DAC for active desktop monitors and to feed an external amp at home.

It is not for driving really demanding headphones to their full potential, it is for casual listening and getting better sound out of a PC on a budget, and for this purpose it is a no brainer.

Shanling H1 Portable Headphone Amplifier Review – A Brawny Baby

Shanling H1 Portable Headphone Amplifier Review

We’ve been treated to a few of Shanling’s products lately; as well as the excellent M1 and M2S players, this little amp promises to give brands like Fiio a run for their money! The entry-level portables market has been truly cornered by Fiio in recent years, so it will be interesting to see what impact Shanling can make here.

Pros:

  • Small, handy unit
  • Thoughtfully designed volume control
  • Well constructed

Cons:

  • None

Design and Appearance

The Shanling H1 amp is a small unit, being 7cm x 6cm and about 1.5cm thick; about half the size of the average mobile handset. The edges are bevelled and the unit feels good in the hand, with enough weight to feel substantial for its size, although the unit is itself not heavy.

Key Features

The main feature is the recessed knurled volume knob which is centred on one side of the amp, which is protected from accidental operation by the amp’s housing. Power/charge lights are on the top, plus there’s a gain switch and micro-USB socket on the rear for charging. That’s it! The H1 is as simple as it gets for an amp, and it’s all that’s needed.

Durability and Build Quality

The Shanling H1 headphone amp is constructed from aluminium and has a pretty solid feel about it. It will probably have no problem being dropped occasionally, but we’ve not tried this here! The volume knob has a smooth, solid feel as it’s turned and it has enough stiffness not to be operated accidentally whilst in the pocket.

Sound Quality

This amp goes loud for its size; we couldn’t resist pairing it up with a HiFiMAN HE-6 which is notoriously difficult to drive. On the low gain setting, and using an incoming line-level signal, the volume goes up to hearing damage levels with the HE-6 on some pieces. Not bad! Of course, we don’t recommend this pairing for getting the best out of the HE-6!

The H1 is designed for portable use, so was tried versus being directly connected to a cheap phone with portable earphones . The sound is faithful and quite neutral, although there is a little more thump coming through with the sub-bass. Music appears to be more relaxed and natural through the amp, where it sounds a little strained with a direct connection. Listening to this amp with a pair of SoundMAGIC E80 earphones is actually very enjoyable!

Summary

Shanling’s new H1 portable amplifier is a palm-sized affair, but Fiio had better start making room anyway!

Do I Need A Headphone Amp?

What’s the point of a headphone amplifier?

Not sure whether to buy a headphone amplifier? This article will inform you of the benefits of adding an amplifier to your existing setup, or buying an amplifier with your new headphones.

When you’re buying some new headphones it’s always good to think about what your source will be; whether it’s an iPhone, Laptop, DAP (Digital Audio Player), your home HiFi or a bit of everything, figure out which has the lowest output and if it can drive your chosen headphone. So if you use a mobile phone as your main source and you’ve decided on some Earsonics SM64 earphones which are very hard to drive, you will need a headphone amp to add some extra power so you can get the most from your new purchase.

There are plenty of headphones designed to be used with mobile phones and other low powered portable devices; these headphones generally have low impedance (up to 32ohm) and high sensitivity (95db and over) so they are very easy to drive. This doesn’t mean that you won’t benefit from an amp; not only do amps add extra power but they can also change the sound by improving sound stage, separation and depending on the amp add warmth or brightness.

Another benefit of getting a headphone amp is that some of them have EQ settings on them, so you can adjust the amount of bass you want depending on what you’re listening to.

If you have decided to go for a headphone amp you now need to decide which one to go for, there are many to choose from and they go for anything between £20 and £1500. Amps can be split into two main groups, portable and desktop. If you are going for a portable amp then you could go for something like the FiiO E11 which is powerful enough to drive most portable headphones, it is a good size and has two EQ settings. If you require more power then you could go for the FiiO E12 or the Just Audio UHA-120. Both of these amps can drive most headphones and they will also improve the sound quality, with the Just Audio being slightly warmer than the E12. For the harder to drive headphones there is the Just Audio AHA-120. This amp has adjustable gain settings and is class A, this provides a less distorted, more accurate sound.

If you only use your headphones at home then you should go for a desktop amplifier as they are generally more powerful. There is a much larger range of desktop amplifiers and you really should know what headphone you will be using before choosing the amp, for example if your headphones have a warm/bassy sound then it’s a good idea to go for a brighter/detailed amplifier. This also works the other way around; a warm sounding amp will compliment bright headphones and balance the sound out.

If you have any questions about choosing the right amplifier then give us a call at Hifi Headphones on 01903 768 910 or you can send an email to support@hifiheadphones.co.uk – we will be more than happy to help.
