Noise canceling headphones and noise isolating headphones, chances are you have probably heard of these before whilst shopping for headphones. Both types of headphones are designed to reduce and block out as much ambient noise as possible.

People often confuse these headphones for each other, but there are many differences in how both works to reduce ambient noise.

Both headphones possess their own advantages. So, if you want to know which one will work best for you, you need to know how they operate and what their differences are.

We are discussing below the main differences of each, so read on for more information.

Noise Canceling Headphones VS Noise Isolating Headphones Fundamental Differences

So, what is the difference between noise cancellation and noise isolation?

In basic terms, the way they work is revealed by their names. Noise isolation headphones work by physically blocking ambient noise with its seal covering your ear, whilst noise canceling headphones work by doing that and electronically canceling out soundwaves.

While both noise canceling and noise isolating headphones work along the same lines, choosing which one suits your needs depends on a variety of factors.

Now to explain in more detail.

Noise Isolating Headphones

Noise isolation, also known as passive noise isolation, works simpler. Noise isolation is not equipped with electronics that block ambient noise, which means they do not need energy or power. These headphones are designed to prevent as much noise as possible from entering the ear canal by creating something like a barrier that prevents outside noise from coming in. 

Their effectiveness is based on how good the seal is and how well the earphones fit you. Good headphones should always have closed backs and tight-fitting ear tips. 

Compared to noise canceling headphones, they are generally cheaper and more effective at isolating higher-pitched sounds. However, they are less effective at blocking lower ranged humming sounds. 

Noise Canceling Headphones

Noise cancellation, also known as Active Noise Cancellation (ANC) works with the use of fancy technology in the form of a built-in microphone with a battery unit that detects external noises, analyzes it, and generates an opposite sound wave that cancels out the noise.

The headphones’ brand determines how effective this system works. This technology has its limitations, however. ANC may not be able to cancel out midrange sounds like people’s voices. And like most electronics, noise canceling circuitries may produce a hissing noise, this might prove a nuisance. Also, these headphones will need a power source or battery to function.

However, ANC works best with those constant lower range, steady unwanted noises such as airplane and car engines, traffic, constant humming noises, and even some chatter. Because of these features, ANC works well for frequent travelers.

Final Thoughts

In conclusion, both types of headphones come with their advantages and disadvantages. Noise cancelling headphones and noise isolating headphones work well in different types of environments. Determining and weighing these is up to you. Know which one better suit your needs and the environment you are in for that sweet noise-less vibe.
