You probably would have heard the term "noise cancellation", and assume it cancel outside noise when listening to audio content with your headphone - which is right!
Even if you get the tightest headphones in the world, it won't be able to cover terrible sounds such as Car horns, or an airplane engine (you know how disturbing that sounds!)
To prevent higher-noise from reaching your ear, some audio equipment companies, e.g. Bose, solve the problem by using a technique called Active Noise Control.
In this noise-canceling headphone guide, I'll work you through the understanding of Noise Cancelling headphones, why they are useful, their drawbacks, and would sum up by recommending the best noise-canceling headphone.

What Are Noise Cancelling Headphones?
It would blow your mind how noise cancellation works...
Breaking it down...
Sound travels in waves; a wave is the representation of vibrations when a vibration occurs, the waves move alternating curves in the opposite direction - that vibration is responsible for the sound you hear.
Look at it this way, when waves occur in the ocean, they have crest (highest point), and a trough (the fall), let's apply that to a sound wave:
The distance between the resting point (bottom of a wave), and the crest (highest point) determines the loudness of audio, its called the amplitude. The number of times the waves pass by a specific point, determines the frequency, the higher the frequency of the wave, the higher the pitch and vice versa.
These are some of the things the microprocessor needs to build a complete waveform of a sound, the more accurate it build the sound, the better the calculation.
So, How Does it Cancel The Noise?
Inside a pair of a noise-canceling headphone, there are microphones designed to pick up unwanted noise from your surrounding.
It builds the waveform, - passes it to the digital signal processor which analyses the sound. The digital signal processor neglects a non-unwanted noise. Its function is to analyze an unwanted noise.
Having done that, the digital signal processor generates the opposite sound wave; this is where the important stuff work:
When the unwanted sounds that the headphone build from the original audio are played 180-degrees out of phase with the opposite sound wave, they cancel each other out.
That's how it works so to speak, the solution to noise cancellation isn't perfect, but it is very close, and as it owns drawbacks/limitations.
Let's look at the...
The Drawback of a Noise-Cancelling Headphones
It is designed to cancel regular outside noises like a car horn, or a drone of an aircraft engine. The reason is that it is easy to figure out regular noises, unlike a human voice where sounds change rapidly.
You might have guessed that you need some sort of power to run this type of headphone correctly. Without adequate power, an active noise-canceling headphone won't be able to function properly.
They are more expensive than regular headphones due to the nature of how they are built.
In some cases where the noise is unbearable, it might reduce the audio quality and add hissing sound.
Having said all that, let's look at the usefulness of using Noise-cancelling Headphones...
- The ability to listen to audio material without the need of raising the volume too high.
- It helps to achieve better noise isolation from ambient sound.
- As a sleeping aid for people with chronic sleeplessness - or people whom outside noise such as snoring, cars honking impact their ability to sleep.
You can see Noise-canceling headphones isn't just for canceling ambient sounds; they can also help in various ways.
Time to make your choice and selection of a Noice Cancelling headphones.
I have carefully sifted through 100's of them, and I am recommending you the best ones below, read through the description, and also check out the user review.
1. Bose QuietComfort 35 II
No doubt, Bose is one of the first choices among audiophiles. With over 2,900 customer reviews, cranking over 4+ rating, then you know this is worth every penny.
QuietComfort 35 comes bundled with lots of jaw-dropping features such as Alexa-enabled voice control, which can be used for voice access to music, information, videos, and more.
It also benefits from the power of three levels of world-class noise cancellation for better listening and a more accurate noise cancellation optimization.
Moreover, the Bose listens to the type of music you're playing and automatically optimizes the level.
Alternatively, you can use the Bose Connect app to adjust the level of noise cancellation. Note that the option is only available on iPhone and iPad, and an Android version is said to be available very soon.
If you want to eliminate those annoying background noise, then this is the best choice for you.
I find the built-in microphone useful, think of how you can cancel outside noise, and still make calls with HQ built-in microphone (Awesome!)
Lastly, one of the features I find interesting is the ability to hear audio from two sources at the same time as your Bluetooth. This feature is handy in cases where you need to connect both your iPhone/iPad and Laptop at the same time.
- Battery life up to 20 hours
- Bundled with Google Assistant and Amazon Alexa

Sony and Bose are the leaders when it comes to cutting edge Headphones (Including Noise Cancelling one's), to be honest.
