How Noise Cancelling Headphones Can Improve Your Listening Experience

Noise cancelling headphones use microphones to listen for ambient sounds and create an anti-noise sound to counteract unwanted sounds. They're ideal to block out rumbles and chatter from trains and planes however they can't do much to cut screeching brakes or your seatmate's animated conversations.

Active noise cancellation requires good isolation, either by padding your ears or a solid seal with earbuds or over-ear headphones. We've tested their ability to mute lower-frequency constant sounds like train and traffic noise also.

What is noise cancellation?

Noise cancelling is a feature that helps listeners focus on their music or audiobook without distraction from distracting ambient sound. Noise cancelling headphones come with microphones that block out external sounds from entering your ears. This lets you listen to your audiobook or music in complete peace.

Active noise cancellation, or ANC is among the most sought-after headphone features available in the present. It's available from a variety of headphone brands, in various sizes and colors, and it's even found in some budget models. The concept is quite simple: headphones or earcups contain mini-microphones that "listen" to ambient sound frequencies and playback equal but opposite anti noise waves to cancel them before they reach your ear.

This is known as destructive interfering. The crests and valleys of the waves cancel each one another out, leaving the music you are listening to. This is particularly effective for monotonous, continuous sounds such as the drone of an airplane engine or the hum of your colleague Bob who is unable to stop talking. However it's not as effective on louder or more frequent sounds that are harder to discern and filter out, such as the click of a keyboard or the alarm ringing from your phone.

Another type of noise isolation is passive, which stifles the sound by forming an ear-to-ear connection with the padding of the ear cups. This is a great option for those who do not want to rely solely on batteries for ANC functionality, but still require a peaceful working environment, or at home.

It's worth noting that every pair of headphones requires some form of power, whether for battery or audio processing, to function. Even though ANC can eliminate most external noise, the headphones won't be able to create a quiet cone around your ears. If the ambient noise is too loud, they'll just bleed into your ears. This is why it's crucial to wear your headphones comfortably enough to not have any gaps in the fit, to get the full benefit of ANC.

How does it work?

The technology behind noise cancelling headphones is based on miniature microphones inside the earcups or earbuds that listen to the sounds around you. The sound waves are processed by the headphones to create a sound wave that cancels them out and blocks them from reaching your ears.

Sound waves, whether coming from the outside or from your music, are composed of oscillating air molecules. This means that the sound waves have a height or the amplitude. It is measured by the distances between peaks on an unsteady graph. Sound waves with higher amplitudes are taller, while those with lower magnitudes are smaller. ANC headphones benefit from this by listening to sounds around you and generating an opposing sound that neutralizes them.

ANC headsets have several features that make them more effective at blocking ambient noises including feedback microphones as well as an ANC chipset. These chips make use of algorithms to invert incoming sound signals and then release an opposing signal, which is much like firing anti-ballistic missiles that shoot down the warheads coming in (again think of military-grade countermeasures seen in war movies).

These opponing signals are produced by two ANC drivers inside each ear cup. When ANC is activated by pressing a button on your headset, the sound of the surrounding environment are lowered or completely eliminated.

The technology behind ANC is impressive but it comes with some tradeoffs. The extra electronics needed to run this technology can add weight and bulk to your headphones. They also draw more power, which can lead to a shorter battery life and possibly high-frequency hiss.

Another issue is that a number of users have reported feelings of dizziness or disorientation while wearing ANC headphones. While this is a problem however, it's usually due something else triggering those feelings, not the ANC headphones itself.

The good news is that the latest ANC headphones are starting to address a few of these issues. The Bowers & Wilkins PX7, for instance, has different ANC modes such as 'office', 'plane' and 'city' with an adjustment 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 adjusts the volume of ANC in accordance with the surroundings.

Over-ear headphones are usually more comfortable than in-ear models. They come with a larger band and cushioned cups which rest on top of your ears. This helps to keep them in position for longer. They are also more effective in blocking out ambient noise. However, it's worth noting that there are exceptions and the most effective headphones to block out noise will depend on your lifestyle and music preferences.

Most over-ear headphones will provide some degree of noise isolation However, the degree of noise reduction will vary greatly by design and the way they fit your ears.

Try swapping out the stock tips of your headphones sony to see if it improves the fit and decreases the background noise. This is also compatible with most earbuds.

In-ear headphones aren't always comfortable for long listening sessions because they are more likely to sit in your ears, rather than over them. They can be more comfortable when you tilt them back or forwards to adjust their size. They are also lighter, which makes them more mobile and easy to carry. In our tests, most earbuds offer some level of noise-isolation, but not as effective as over-ear headphones.

What should I look for in noise cancelling headphones with noise cancellation?

The best noise cancelling headsets reduce ambient sound to allow you to concentrate on your audio without being distracted by the surrounding. To achieve this, they typically employ active noise cancellation (ANC) but not all ANC headsets are created to be equal.

In-ear and over-ear headphones provide excellent noise isolation. In-ear headphones are more compact 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 often have a better sound. In-ear models are more affordable and still deliver a solid performance.
