In the present time, the variety of headphone is too wide and it is really difficult to choose the right one.

You might get attracted to the one which your favorite celebrity endorses but before you buy any pair it is very important to know the technical aspects so that you can choose the right one according to your need. So given below are technical aspects related to the headphones.

In-ear headphones

In-ear Bluetooth earbuds or commonly called as in-ear monitors get fit directly inside the ear canal. It has two technical advantages.

First is they deliver amazing sound quality as they are quite close to the eardrum and the second is that they exit the entrance of the ear so are quite good at cutting out external noise. There are various kinds of In-ear headphones. You can choose the one which fits your ear canal.

On-ear headphones

On-ear Bluetooth wireless earbuds or commonly called supra-aural headphones are placed on the top of the ear. Same way like in-ear headphones, they direct sound straight down the ear canal, but don’t cut out on external noises, and may even be a disturbance to the person sitting near to you.

A number of people find them more comfortable as they believe it doesn’t trap heat as the In-ear headphones do. They are best when it comes to portability and sound quality.

Over-ear

These headphones cover the entire ear. As they have a huge size it makes room the sound volume louder plus the bass quality is better.

The driver is actually placed quite away from the ear so it produces a more airy sound akin to what you actually listen from the speakers. They are good when it comes to cutting out the noise outside plus it has a great look.

Open and closed back

You will observe that headphones (over-ear ones particularly) explained as being either “open back” or “closed back”. This actually brings into the context whether the back of the ear cups is open or sealed.

“Closed-back” headphones provide better noise isolation and be inclined to have a more powerful which is same as in-ear headphones.

“Open back” headphones comprises of more sound leakage and let in more ambient noise, but gives you what audiophiles often explain as a more natural sound.

Drivers

In a pair of headphones, the driver is the most important component. It changes an electrical signal into sound pressure that is in simple language, it creates the sound.

There are various kinds of driver, but they all mainly comprise of magnets, voice coils and a diaphragm. The components result in the diaphragm to vibrate, and these vibrations create sound waves that our ears understand as sound.

Since in-ear headphones cannot keep a large driver, a growing number opt for a dual-driver approach. Rather than including a single driver handling the whole frequency range, there’s one especially for bass and the other one for the mid and high frequencies.

Sensitivity and Sound Pressure Level

Sensitivity and Sound Pressure Level (SPL) both are interrelated, and any one of them can be used on headphone spec sheets. They designate how loud the headphones will go. Sensitivity depicts how professionally an electrical signal is transformed into an acoustic signal.

SPL is how sensitivity is calculated and is often shown as decibels of SPL per mill watt (although there is no absolute standard for this). Most headphones are in between the range of 85-120 dB SPL/mW.

To give some context, regular city traffic is near about 80dB, a shouting voice 105dB, and a jet taking off 130dB.

Thus these are some of the technical aspects of the headphones that one must know before heading out to buy the best pair for an uninterrupted audio experience.
