20 Trailblazers Leading The Way In Headphones Noise Cancelling
How Noise Cancelling Headphones Can Improve Your Listening Experience
Noise cancelling headphones rely on microphones to listen for ambient sounds and generate an anti-noise sound that blocks out unwanted sounds. They're great for blocking out rumbles as well as chatter from trains and planes but they won't help to stop the squealing brakes or your friend's animated conversations.
Active noise cancellation requires a good seal whether it's earbuds, over-ear headphones or padding around the ears. We've also tested whether the headphones can block lower-frequency sounds like traffic and train noise.
What is noise cancellation?
Noise cancelling is a feature that helps listeners focus on their music or audiobook without distraction from background noise. Noise cancelling headphones are equipped with microphones that block external sounds from entering your ears. This lets you listen to your music or audiobook in peace.
Active noise cancellation (ANC) is among the most commonly used headphone features that are available. It is available from many different brands of headphones in a wide range of sizes and colors, and even on some budget models. The technology behind it is simple: the earcups or earbuds are equipped with mics that "listen" to ambient noise frequencies, then play back equal but opposite anti-noise waves to block them out before they reach your ears.
This is known 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 particularly effective for repetitive, constant sounds like the hum of an aircraft engine or Bob's incessant chatter. However, it's less effective on high-frequency or sudden sounds that are harder to discern and filter out like the ping of a keyboard or the alarm sounding from your smartphone.
The foam padding in the ear cup can be used to reduce noise. This is a good choice for those who do not want to rely solely on batteries for ANC functions, but require a peaceful working environment, or at home.
All headphones require power to function, whether it's an audio processing or battery. Although ANC can cut out the majority of external noise, the headphones can't create a solitary cone around your ears. If audio headphones is too loud, they'll simply bleed through to your ears. This is why it's crucial to wear the headphones snugly enough that they don't have any gaps in the fit, to get the maximum benefit from ANC.
How do you make it work?

The technology behind noise cancellation headphones involves miniature microphones in the earcups or earbuds which listen to the sounds around you. The sound is processed in the headphones to create a sound wave opposite that blocks the sound waves out and stops them from reaching your ears.
Sound waves, regardless of whether they're emanating from outside or from your music, are composed of oscillating air molecules. This means that sound waves have a size or amplitude. It's measured by the distance 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 opposite sound that neutralizes them.
ANC headsets are equipped with several features to block out background noises like feedback microphones and ANC chipsets. These chips use algorithms that invert incoming sound and then release a counter-signal which is similar to firing antiballistic missiles at incoming warheads.
The ANC drivers inside each ear cup generate these opposite signals. When the ANC is activated by pressing a button on your headset, the sounds of the surrounding noises are reduced or removed.
While the technology behind ANC is impressive, it comes with a few trade-offs. The additional electronics required to make this technology function can add weight and bulk to your headphones. They also consume more power, which could result in a shorter lifespan of the battery and some high-frequency hiss.
Another issue is that a number of users have reported feeling disorientation or dizziness when wearing ANC headphones. It can be very frustrating, but is usually caused by something else, not necessarily the ANC.
The good news is that the latest ANC headphones are starting to address a few of these issues. The Bowers & Wilkins PX7, for instance, comes with different ANC modes, including "office," "plane," and 'city', with an adjustment slider that lets you customize the volume of external sound you want to pass through. Apple's new AirPods Pro 2 also feature the same feature, and comes with the 'Ambient Aware mode that adjusts the volume of ANC to your surroundings.
What are the top headphones for noise cancellation?
Noise cancelling headphones can make a a huge difference to your listening experience. They can help you focus in the workplace or block out engine noise on trains, planes and buses. These headphones are ideal to use for commutes or working from home. They are compatible with any audio device, including smartphones, tablets and computers. They can be pricey but now there's an option of wireless ANC headphones that will fit any budget.
The most effective pair of headphones that block out noise will be comfortable to wear for extended periods with a tight seal around your ears. The battery lifespan should last at least 30hrs, which is enough to get you through the daily commute or working day. Make sure whether the audio source is supported, whether that be Bluetooth or USB-C.
Over-ear headphones tend to be more comfortable than in ear models. They feature a wider band and cushioned cups which are placed over your ears. This helps keep them in place for longer. They are also more effective in blocking out ambient noise. There are exceptions, and the best noise-cancelling headphones for you will be determined by your lifestyle and music preferences.
The level of noise reduction will vary depending on the design and how well it fits into your ears. A bad fit could let in more ambient noise and it can even affect the quality of the bass. Try swapping out the stock tips of your headphones to see if this improves the fit and reduces ambient noise. This works with most earbuds.
In-ear headphones can be less comfortable for long listening sessions, as they tend to rest in your ears rather than over them. They can be more comfortable when you tilt them forwards or backwards to adjust their fit. They're also usually lighter, making them more portable and more mobile. In our tests, all earbuds provide a certain amount of noise isolation but it's not as good as over-ear headphones.
What should I look out for when purchasing headphones that cancel out noise?
The best noise cancelling headphones reduce the background noise so that you can focus on audio without being distracted by your surroundings. To achieve this, they typically employ active noise cancellation (ANC) but not all ANC headsets are made equal. It is crucial to think about the type of ANC and whether it's in-ear or in ear, as well as their build quality.
In-ear and over-ear headphones provide superior noise isolation. In-ear headphones are more portable and less bulky. While over-ear models are more comfortable however, they are more expensive. Over-ear headphones are generally more expensive but often offer a better sound quality, while in-ear models offer an affordable option with a solid sound quality.
Some ANC headphones allow you to alter the level of ANC to suit the situation. For instance, you might prefer to keep ANC off when traveling on a plane or public transit but activate it when in the office or at home, to block out the whir of your PC's cooling fans or your neighbor's lawn mower. Some headphones also feature a 'transparency mode' that lets some external noise through, allowing you to hear important sounds from the outside, like traffic or conversations.
The best noise cancelling headsets are equipped with ANC and Bluetooth for wireless listening. Certain headphones support the aptX or aptX HD Bluetooth codes, which provide superior audio quality when compared to conventional Bluetooth.
There are ANC headphones that cost less than PS50. However, the Bose QC35 II over-ear headphones provide the best value. Their ANC is top-quality and has a slight delay between tracks to let you hear your own voice when talking and they also have high-quality audio that's clear and detailed.
Children's noise-canceling headphones are worth considering, particularly for children who suffer from sensory overload and require help in processing auditory stimuli. They typically come with a broad variety of colors and designs targeted at children, with some even licensing popular cartoon or video game properties. They are more comfortable for children than traditional headphones, and they often include parental controls like volume-limiting features.
