The Worst Advice We've Ever Seen About Headphones Noise Cancelling Headphones Noise Cancelling
How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones use microphones to pick up ambient sounds and create an anti-noise sound that counteracts unwanted sounds. They are ideal for blocking out rumbles and chatter from planes and trains, though they don't make much difference to the sound of the squealing brakes or your friend's animated conversations.

Active noise cancellation requires a great seal whether it's earbuds, over-ear headphones, or padding around the ears. We've also tested how well the headphones block out lower frequency noises like traffic or train noise.

What is noise cancellation?

Noise cancellation is a feature which lets listeners focus on their music or audiobook without being distracted by background noises. Noise cancelling headphones are equipped with microphones that block outside sounds from reaching your ears. This lets you enjoy your audiobook or music in peace.

Active noise cancellation (ANC) is among the most common headphone features that are available. It's offered by a variety of headphone brands, in various sizes and colors, and it's even available on a few budget models. The technology is simple: the earcups or earbuds have mini-microphones that "listen" to ambient sound frequencies and play back equal, but opposite noise waves to block them before they reach your ear.

The crests and troughs of these waves cancel each other, a process referred to as destructive interference, leaving you with nothing but the music you're listening to. This works well on repetitive, constant sounds, such as the drone of an aircraft engine or Bob's constant chatter. However it's not as effective on louder or more frequent sounds that are more difficult to discern and filter out like the ping of a keyboard or the alarm ringing from your phone.

Another form of noise isolation is passive, which stifles the sound by forming a seal with your ears with the padding of the ear cups. This is a great option for those who don't want to rely on batteries for their ANC capability, but still prefer a peaceful environment when working or at home.

It's worth noting that all headphones require some kind of power, whether for battery or audio processing, for them to function. Although ANC can cut down on most external noises, headphones cannot create the illusion of a cone-shaped silence around your ears. If the sounds around you are loud enough, they will simply bead 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 maximum benefit from ANC.

What exactly is it that makes it work?

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

Sound waves, whether they're emanating from outside or from your music, are composed of air molecules that oscillate. 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 greater intensities are larger, whereas those with shorter amplifies are smaller. ANC headphones benefit from this by listening to the sounds around you and generating an opposing sound that neutralizes them.

ANC headsets have several features that help in blocking ambient sounds such as feedback microphones and an ANC chipset. These chips make use of algorithms that invert incoming sound and then release a counter-signal, which is akin to launching antiballistic missiles against the warheads coming towards them.

The ANC drivers inside each ear cup create these opposing signals. When ANC is activated by pressing a button on your headset, the sound of the surrounding environment are reduced or even completely eliminated.

The technology behind ANC is impressive but it has some drawbacks. The additional electronics required to enable this technology can make your headphones heavier and larger. your headphones, making them bulkier than comparable models. They also use more power, which can cause a decrease in the life of the battery, as well as high-frequency hiss.

One other issue is that many users have reported experiencing disorientation or dizziness when wearing ANC headphones. While this can be frustrating, it's usually due to something else that triggers these feelings, not the ANC itself.

The good news is that the latest ANC headphones are beginning to address a few of these issues. The Bowers & Wilkins PX7, for example, offers different ANC modes like "office", 'plane' and 'city', with a slider that lets you customise the amount of external sounds that you wish to hear. Apple's AirPods Pro 2 feature a similar feature, which includes an "Ambient Aware mode' that digitally alters the amount of ANC depending on the environment.

There are exceptions, however, and the most effective noise-cancelling headphones will be determined by your music and lifestyle preferences.

The majority of over-ear headphones offer some level of noise-isolation, but the level of noise reduction will differ greatly based on the design and how well they fit in your ears. A poor fit could allow in ambient noise and even affect the quality of bass. Try changing the tips of your headphones to see if it improves the fit and lessens the background noise. This works with earbuds of all types.

In-ear headphones aren't always comfortable for long listening sessions as they tend to rest in your ears rather than over them. You can alter the size of your headphones by tilting them forward or backward. They are also lighter, making them more mobile and easy to carry. In our tests, we found that the majority of earbuds offer noise-isolation. However, they're not as effective as a pair of over-ear earphones.

While headphones with over-ears can be more comfortable for extended periods, in-ear headphones offer greater portability and can be less bulky. Over-ear headphones are generally more expensive but often offer superior sound quality while in-ear models provide an affordable option that still provide solid performance.

Some ANC headphones allow you to adjust the level of ANC to suit the situation.
