How to buy a perfect Headphone or Earphone online?

Consider that you have to buy a new Headphone or Earphone for yourself then how will you get them?

Simple, You will walk into the nearest store grab some of the Headphone and Earphones you will test them out and then you will decide that is it a perfect choice for you or not.

But if I tell you that you can take the Headphone or Earphones only from a online store then it will might get a tough task.Right!

In that case you will probably go with the Headphones or Earphone which is of a well known Brand or you will check the ratings over the product or by looking at the price that this Headphone or Earphone are costly then it might be the best one or you will bye it just by it good appearance.Without checking its sound quality.

Today by this article I will tell you guys that how to buy a perfect Headphone or an Earphone just by looking at its Specification's

Before buying a new Headphone or an Earphone through online stores just go into its Specification's box and check out these 5 point which i am going to tell you

1. Drivers
2. Frequency Range
3. THD (Total Harmonic Distortion) 
4. Impedance 
5. Sensitivity (Sound Pressure Level)

 By looking at this 5 points you can easily tell that this Headphone or an Earphone is the best choice for me or you can compare the Headphones or Earphones

Today we will talk about these 5 topics and will see that which values can make a Headphone or Earphone best or worse lets get started.

1. Drivers

What are drivers?

The element inside a headphone or an earphone that converts an electrical signal into sound is known as a driver unit. You could picture it as a tiny loud speaker in your headphone or earphone. A driver unit is made of a magnet, voice coils and a diaphragm. A driver unit's size is useful to gauge the capabilities of producing sound. 

Larger the driver size louder the sound its size varies from 6mm to 12mm in Earphones and 40mm to 100mm in Headphones

as Headphones are bigger in size so they need a bigger driver to work in it.

Note- Look for a headphone or a earphone with bigger driver that is 12mm for a Earphone and 100mm for a Headphone

2. Frequency Range

If we talk about ourselves then the hearing range of a human being is 20Hz to 20kHz so by keeping that in mind if we take a look onto a headphone or a earphone which should have a high bass so less the starting range of a headphone or a earphone better the bass

Like, if we take two Headphones. A and B so if the starting range of Headphone (A) is 10Hz/20kHz and Headphone (B) starts from 18Hz/23kHz so if you are looking a Headphone specially for bass the Headphone (A) will give you better bass output the Headphone (B).

Note- Lower the starting Frequency range better the Bass output

3. THD (Total Harmonic Distortion)

What is Total Harmonic Distortion?

The total harmonic distortion is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. 

In simple words consider that you have a audio file in you Mobile in its original format and when you plug in your headphones or earphones on you will get some amount or Distortion in it.

That number of distortion should be as low as possible it should be near 0%

For example if a Headphone has 1% of THD in it and other one has 0.1% THD go with the Headphones which has 0.1% THD in it because it will provide you better sound output.

Note- Lesser the THD value Better the sound output

4. Impedance 

What is Impedance?

Impedance means the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance. Unit is Ohms.

So if you are looking for a Headphones or Earphones to connect to your Laptop or iPod or Tablet or your Smartphone and use it take the headphone or a earphone which has 32Ohms of Impedance 

But if you are a professional DJ or a Sound artist and want to connect your headphone with your Amplifier take a headphone or earphone which has 200Ohms of Impedance 

Note- For Smartphone and laptops take 32Ohms Headphone or earphone and for Professional use go with Headphones with 200Ohms or higher.

5. Sensitivity (Sound Pressure Level)

What is SPL? (Sound Pressure Level)

SPL is actually a ratio of the absolute, Sound Pressure and a reference level and it is measured in decibels(dB)

Higher the dB range in your headphone or earphone you will get better sound output for example if we consider 2 headphones with different decibels level that is Headphone (A) has dB level of 90 and on the other hand Headphone (B) has the dB level of 120 then the Headphone (B) will provide you better sound output that compare to Headphone (A).

Note- Higher the dB level better the sound output.
