How Do I Choose the Best Headphone AMP?

Headphone amplifiers are specially designed to produce higher volumes, crisper sound, and better current capacities. They act as an interface between headphones and audio sources through an analog or digital connection. Most stereo receivers have integrated headphone amplifier circuits, which may perform well with their customized earphones, but they are often unable to perform optimally with high-performance headphones. It usually isn’t advisable to use high-performance headphones on inbuilt amplifiers because that’d result in reduced sound quality. To optimize your sound quality, you will need headphones amplifiers designed for high-performance headphones.

Headphone amps used to be associated with professional recording studios. Producers use them to monitor the progress of recording sessions. With the advancement in headphone technology, the demand for headphone amplifiers has been steadily increasing. A headphone amplifier is now more mainstream. Let’s begin with the different types of headphone amplifier:

Portable headphone amplifier: this type of amp is designed to be compact and portable. It’s mostly used for mobile music devices like iPods or laptops. It can fit into pockets and small pouches and are powered by batteries.
Desktop headphone amplifier: this is larger in size than the portable headphone amp. They’re designed to be stationary. They cannot be used in transit. They are suitable for personal computers, home theaters, stereo systems and laptops.
Full-size headphones amplifier: this is the largest in size of all the headphone amplifiers, designed to be used in a permanent listening spot. It gives the highest level of performance.

For each of these types above, there are dozens of headphones available. Before you make a choice of the headphone amplifier to purchase, consider the features that are more compatible with your needs.

Price

The price of a product is usually the ultimate limiting factor when it comes to making purchases. You might not be able to buy the headphone amplifier of your choice because the price is higher than you can afford; certain features and the brand’s quality can be responsible for this. Therefore, it’s important that you don’t lock your budget until you find out which headphone amp is best for your headphones.

Headphone amplifiers can go for as high as $800 and as low as $29. This is a wide range, but you don’t want to go for a cheap headphone amplifier that you won’t make the most of for whatever reason. We did come across these types, but we tossed them aside because we’re interested in giving you information on headphone amplifiers of better value.

Features

Depending on the type of headphone amplifier you are going for, there are certain features you need to consider critically before making a choice. Here are the important features that can come with a headphone amplifier.

Analogue input and output
RMS power
Digital sound processing
Pre-amplifier/loudspeaker amplifier
Signal-to-noise ratio
Power output
Integrated DAC
Number of channels

Construction and Design

Even the most basic headphone amp comes with analog and digital output. The input can either be a stereo RCA jack or a 3.5mm headphone jack while the output is in the form of a 3.5mm headphone jack. With this feature, you can hook up to your music source device (computer, laptop, mobile phone, CD, etc) with an RCA cable or 3.5mm cable mini stereo. The headphone is plugged into the amp which is itself plugged into the music source device.

Power outputs for headphones are calculated in milliwatts (MW). The average headphone requires less than 20MW to reach its maximum output. However, impedance and sensitivity ratings can increase the power output requirement for some headphones. Based on the preceding ratings, a headphone amp with more than 500MW can run most headphones. Do consider the specific ratings of your headphones before choosing a headphone amp.

Very common with most headphone amps are integrated DAC features. This feature allows for a digital connection between the sound source component and the headphone amplifier. This connection can either be a USB or S/PDIF. A headphone amplifier with this type of connection is most desirable when the sound source is a laptop or a computer. It can also work for a CD transport to be connected directly to the headphone amplifier. It has been argued that DACs can introduce noise during the performance due to the digital circuits. Well-designed headphone amps can eliminate the chances of this negative effect.

Performance and Ease of Use

The RMS (root-mean-squared) is the measurement of the actual power a headphone amplifier is getting. This measurement determines how loud the headphone will be at its peak. Noise is calculated in decibels. Certain levels of noise aren’t healthy for humans because they can cause hearing damage. The safe decibel level is beneath 120 decibels for short periods and 85 decibels for longer periods of time. Anything beyond this can potentially cause hearing damage.

The signal-to-noise ratio is a major factor to consider when choosing a headphone amplifier. The signal-to-noise ratio is the measurement of the amp’s amount of noise compared to that of its source. We already mentioned that the sound from the source is measured in decibels. The greater this ratio is, the lesser the noise, which isn’t the case in the signal of origin. The importance of this ratio to the performance of your headphone amplifier cannot be over-emphasized.

An example of the Digital Sound Processing (DSP) is the popular Dolby headphone format for standard headphones. This feature improves the overall sound experience of headphone amplifiers by digitally modifying and improving the sound processing of the headphone amplifier.

The preamplifier/loudspeaker amplifier feature allows the headphone amp to play dual functions. The preamplifier function reduces interference and prepares a small electrical signal for further processing or amplification. As much as this feature gives the headphone amp a lot of flexibility, it’s more expensive to run and it doesn’t exactly increase the performance of the headphone amp itself. For this feature, you need to prioritize.

Most headphone amplifiers come with one to eight channels, each of which arranges independent stereo line distributions into a single-track package. This feature is important for monitoring flexibility. Also, more channels means more provision of multiple signal distributions
