Are you looking to pump up your music? Do you know that an amplifier headphone can help you reach the 
required volume level?
In layman terms, an amplifier is a device which amplifies the sound thereby making the output louder and enhancing the listening experience. With the growing dependence on Smartphone and tablets increasing, a headphone amp has become more of a necessity because it delivers amazingly realistic audio to the ears.
In reality, a good speaker requires high amplification power to deliver the best output. And, headphones, as we all know, are the miniature version. So, they also need powerful amplifiers to sound the best to the ears.
Read our latest guide about the best headphone amplifiers.
Why do you need a headphone amp?
An excellent headphone amplifier will enhance the performance of the music and take it one level up. E
very smartphone features an amp – but it’s a weak one. The music will not be clear, and you can miss the intricate music details. A high quality headphone amplifier digs and gets access to nuanced low-level information which is often hidden during when the recording is done. Due to which the sound quality is improved, and you get to enjoy the minute details of the song.
For those of you who love to hear powerful music, a good quality amp headphone will serve the purpose.

Types of amplifier technologies
When it comes to amplifier technology, there are two types primarily solid-state amps and tube amps
Solid-state amplifier –
These amps are one of the most common types of headphone amp available in the market. It uses a mixture of diodes and transistors to amplify the required audio. When compared to tube amps, the solid-state amps are small, reliable and less expensive.
Tube amplifiers –
The tube amp makes use of one or more vacuum tubes to amplify the sound. Since these amplifiers make use of vacuum tubes; if the tubes go bad, it will affect the tone, sound quality and result in irritating distortions. Though you can replace the tubes but not all of them are replaceable. It usually features three types of tubes – preamp, rectifier and power. While tube amps are costly, they deliver fantastic sound quality to the listener.
These amplifiers deliver the best result when paired with high-draw audiophile design and high-impedance. Furthermore, with the growing use of headphones for Smartphone, companies are developing portable amps. Many of the amps available are integrated with DAC technology (digital-to-analog converter) and USB connection. A few amps boast of optical ports and coaxial for greater flexibility.
Type of headphone amplifiers
Analog only
Usually, these amps have either one or two analog inputs. In such a kind of amplifier, you can plug a music player or the audio output from the phone. Because these require AC power to work, analog amps are widely used only in homes. Furthermore, if 
the sound device lacks a headphone jack, these amps will come to the rescue.
Headphone amps with USB DAC
These offer a USB audio input for the phone or computer. Some of the models will also feature DAC due to which these are mostly battery operated. You can take them anywhere and enjoy good quality music. Interestingly, these amps possess the power of driving pair of powered speakers effortlessly.
Advantages of a headphone amplifier
After understanding the types of headphone amp, you need to know why an amplifier will increase the listening experience.
Headphone jack missing in the audio component
There are many pieces of systems which do not have a headphone jack making life tough for music listeners. Some very costly and high performing audio systems fall in this category. You can add the right set of earphone amp to enjoy the music without any disturbances.
Enhancing the audio performance
For those who want to know the subtle details of the music, an amplifier is a perfect solution. It will only make the sound clear but will provide all the intricate details which otherwise go unnoticed when hearing on a regular headphone.
Helps in increasing the volume of high impedance earphones
A plethora of headsets require a significant amount of power to deliver the best music. But, the power supplied by the amplifier of a Smartphone is not good enough to drive the headphone. Adding a high-quality amp will bring life back to the expensive headset.
Factors to consider before buying a headphone amp
Before choosing the headphone amp for an enriching musical experience, consider the following factors:
Impedance and sensitivity
The sensitivity of a headphone indicates the amount of power required by the headphone from the amp to drive appropriate sound quality. A high sensitive headphone will offer 100 dB or more of sound for 1mW power or amplification supplied. Therefore, the lower the sensitivity of the headset, the higher power it will require to play clear and loud music.
Impedance, on the other hand, indicates the amount of electrical load which the headphone can take from the amplifier. Maintaining a balance between headphone impedance and amplifier impedance is a daunting task. Furthermore, if the impedance of the amplifier is less than the headset, it will result in electrical damping. This makes the sound more articulate. In general, the higher the impedance, the more are the chances of using an amplifier to enhance the volume and sound quality.
Integrated DAC (Digital to analog convertor)
One feature which is gaining the attention of the consumer is the DAC. A headphone amp featuring an integrated DAC helps in establishing a digital connection between the source and the amplifier. The connection can either be a USB or using a coaxial. If you primarily listen to music from your laptop or Smartphone, you need a headphone amp with integrated DAC.
Size
If you’re looking to buy an amp for the home, it’s always great to buy a portable one because you can use it on the go. A small size amp is not only compact but also lightweight, which helps in carrying it everywhere.
Type of connection
Choose an amp that has the output according to your headphone. Otherwise, you will end up purchasing an adapter to connect the two.
Number of inputs
Before buying an amplifier, ensure that it features a sufficient number of inputs which are required to connect to the music 
source. If your amp features a DAC, you can only make a digital connection using a digital cable.
Distortion
You cannot ignore the performance of the amp because it ultimately decides the quality of sound. Distortions if present can hamper the listening experience. Therefore, look for an amplifier with THD (Total Harmonic Distortions) and IMD (Intermodulation Distortions) less than 1% at rated output power. The lower the distortion, the better is the amplifier.
Signal-to-noise ratio
This ratio measures the noises of the amp and the source music signal. A larger ratio is preferred because it tells that there is less noise when compared to the source signal. Signal-to-noise ratio is critical because the headphones rest on the ears and the sound is easily detectable.
Look for these features before purchasing the best headphone amplifier and enjoy listening to your favorite song. Always remember any headphone will sound good, but with a headphone amplifier, the sound is worthy and does justice to the musician.
