How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones use microphones to detect ambient sounds and generate an anti-noise sound that counteracts unwanted sounds. They are great to block out plane and train chatter, but they won't help you block out your seatmate's animated conversation or snarling breaks.

Active noise cancellation requires great isolation, either by padding around your ears or an earbuds that are sealed or over-ear headphones. We've also examined how the headphones muffle lower-frequency sounds like traffic and train noise.

What is noise cancelling?

Noise cancellation is a feature that allows listeners to concentrate on their music and audiobook without being distracted by distracting background sounds. Noise cancelling headphones come with built-in microphones that actively block external sounds before they get to your ears, effectively reducing the outside world so that you can enjoy your tunes or audiobook with peace.

Active noise cancellation (ANC) is one of the most common headphone features on the market. It is available on many different brands of headphones with a variety of sizes and colors, and even on some budget models. The technology behind it is surprisingly simple: the earcups or earbuds have miniature microphones that "listen" to ambient noise frequencies, then play back equal but opposing anti-noise waves to eliminate them before they reach your ears.

This is referred to as destructive interfering. The crests and valleys of the waves cancel each one another out, leaving the music that you are listening to. This is great for monotonous, continuous sounds like the drone of an airplane engine, or the hum of your colleague Bob who is unable to quit. However, it's less effective on louder or more frequent sounds that are harder to detect and eliminate, such as the ping of a keyboard or the alarm ringing from your smartphone.

Another type of noise isolation is passive, which blocks the sound by forming a seal with your ears with the padding of the ear cups. This is a good alternative for those who do not want to rely on batteries to provide their ANC capability, but still need to have a peaceful environment while working or relaxing at home.

It's important to remember that every pair of headphones requires some form of power, whether it's for battery or audio processing, to function. Although ANC can eliminate most external noise, the headphones won't be able to create a cone of silence around your ears. If the ambient sounds are too loud they'll just bleed into your ears. This is the reason it's essential to wear the headphones in a snug way enough that they don't have any gaps in the fit so that you can enjoy the full benefit of ANC.

How do you make it work?

The technology behind noise cancellation headsets involves tiny microphones in the earcups, or buds, that listen to the sounds around you. The sound waves are processed in the headphones to create a sound wave opposite which cancels the sound waves out and stops them from reaching your ears.

Air molecules oscillate and produce sound waves. This means that sound has a height or the amplitude. It is measured by the distances between peaks in an oscillating graph. Sound waves with higher amplifies are larger, while those with smaller amplitudes are smaller. ANC headphones benefit from this by focusing on the sounds around you and creating an opposing sound that neutralizes them.

ANC headsets feature a variety of features that can make them more effective in blocking ambient noises, including feedback microphones and an ANC chipset. These chips employ algorithms to reverse incoming sound signals and then release an opposite signal, which is similar to launching anti-ballistic missiles to shoot down the warheads that are incoming (again think of military-grade countermeasures Immerse yourself in superior sound with Anker A3i war films).

The opposite signals are generated by the pair of ANC drivers in each ear cup. When you activate the ANC by pressing a button on your headset, the sounds of the surrounding environment are minimized or eliminated.

The technology behind ANC is impressive but it has some drawbacks. The additional electronics required to enable this technology can add weight and bulk to your headphones. They also use more power, which could lead to a shorter battery life and potentially some high-frequency hiss.

One other problem is that a lot of users have reported feelings of dizziness or disorientation while wearing ANC headphones. Although this can be a source of frustration however, it's usually due something else triggering those feelings, not the ANC itself.

The good news is that more advanced ANC headsets are beginning to address a few of these problems. The Bowers & Wilkins PX7, for instance, has several ANC modes like "office," "plane," and 'city', along with an adjustment slider that lets you adjust the amount of external noise that you wish to hear. Apple's AirPods Pro 2 feature a similar feature, and a 'Ambient Aware mode' that digitally adjusts the volume of ANC according to your surroundings.

What are the top headphones for noise cancellation?

The degree of noise reduction will vary depending on the design and how it fits in your ear. A poor fit can let in more ambient noise, and could affect the quality of the bass. You can try swapping out the stock tips of your headphones to see if this improves the fit and decreases the background noise. This works with earbuds from all brands.

In-ear headphones may not be as comfortable for long listening sessions, as they tend to rest on your ears instead of over them. They can be more comfortable when you tilt them forwards or backwards to adjust their fit. They are also lighter, making them more convenient to carry and more portable. In our tests, most earbuds offer some level of noise cancellation, but it's not as impressive as with over-ear headphones.

What should I look for in noise cancelling headphones?

The best noise cancelling headphones reduce ambient noise, allowing you to concentrate on your music without being distracted by your surroundings.

It is important to take into consideration the type of ANC used, whether they're over-ear or in-ear, and their build quality.

Both in-ear and over-ear headphones provide excellent noise isolation. In-ear headphones are more portable and less bulky. While models with over-ears can be more comfortable, they can also be more expensive. Over-ear headphones are more expensive, but they typically have better sound. In-ear models are less expensive and still deliver a solid performance.

Certain ANC headphones allow you to alter the level of ANC to meet the specific needs of the situation. For example, you may prefer to turn ANC off when you travel on public or an airplane transportation, but enable it when in the office or at home to block the whir of your PC's cooling fans or the lawn mower of your neighbor. A lot of headphones have a 'transparency mode' that allows some external noises to pass through, meaning you can hear important sounds such as traffic or conversation.
