For anyone who regularly travels by air, active noise cancellation technology in headphones is a boon. This helps to reduce strain on your ears by blocking out the loud hum of the airplane engines, and it also makes it a lot easier to listen to audio through your headphones. Although the technology tends to work best in an airplane cabin, there are plenty of other use cases where it works as well, including on a commuter train or bus, in an office environment, or even at home to block out the hum from your ceiling fan or air conditioner.
Headphones that offer active noise cancellation aren't typically affordable, and the best performance is priced at a premium. However, we've seen some recent launches that offer decent active noise cancellation at more reasonable prices. This feature also isn't largely restricted to over-ear headphones anymore; we've seen some impressive in-ear and true wireless earphones with active noise cancellation recently. Here's our list of the best active noise cancelling headphones and earphones that you can buy right now.
Before we get to the list, we should start with an explanation of the technology itself, and how it works. Active noise cancellation functions by picking up the sounds of your surroundings and creating ‘reverse' frequencies — the headphones emit sounds at the same amplitude but with an inverted phase compared to the original sound. This combines with the waves of the background sound, to form new waves in a process called ‘interference', which effectively cancels out the sound going into your ears.
As a result, you hear less of the background ‘noise', and in some cases with good active noise cancellation, you might hear nothing at all. It works best with sounds that are steady, since the microphones can pick up and reverse these frequencies easily without interfering with what you actually want to hear. Irregular sounds such as voices, honking, and anything that isn't flat, won't get cancelled by the system, and you'll still be able to hear it. Therefore, active noise cancellation isn't the same as sound-proofing; it simply reduces noise in certain environments.
For a more detailed explanation, check out our guide on getting started with active noise cancellation.
The best way to listen to music is with no other sounds in the background, so you can concentrate on what you're listening to and pick up on fine details that might otherwise get drowned out. Unfortunately, and especially with headphones, this isn't always possible; outside sounds will filter in and take away from the experience, no matter how good the passive noise isolation is. Noise cancellation aims to fix this by cutting out noises that can slip through even the best padding and isolation.
It's also a good way to get some sleep in a noisy environment. Many frequent fliers swear by active noise cancelling headphones, but the technology works in many situations on the ground as well.
Bose is widely considered the leader when it comes to active noise cancellation on consumer headphones, and the Bose Noise Cancelling Headphones 700 has us nodding in agreement. Priced at Rs. 34,500, this is the most effective and customisable active noise cancellation we've heard on any headphones, offering the absolute starkness of complete silence, good ambient listening, or anything in between.
A key feature here is the ability to adjust the level of noise cancellation, so users can choose exactly how much of the effect is audible. Although we liked the starkness of the ‘level 10' setting, we see the appeal of having ten adjustment points for people who might want to tone things down a notch and maintain some awareness of their surroundings.
We spent a lot of time using the ‘level 5' setting since this gave us a bit of ambient awareness while still bringing noise levels down to a comfortable point. It's most effective with loud droning sounds such as airplane engines, but it worked effectively even in everyday situations such as commuting, in the office, or at home. The level of quietness achieved was refreshing, and also helped us hear things such as dialogue in movies and TV shows more clearly, apart from making music more immersive and distraction-free.
The downside of the Bose Noise Cancelling Headphones 700 is that no advanced Bluetooth codecs are supported. While sound quality is good, it falls short of the capabilities of many other competing options when it comes to detail and cohesiveness. Nonetheless, the Bose Noise Cancelling Headphones 700 remains unmatched purely on the quality of active noise cancellation.
Professional audio brand Shure is best known for its studio-grade equipment, but the Shure Aonic 50 is part of a new approach by the brand to appeal to retail consumers. Priced at Rs. 33,999, the Aonic 50 is a technically advanced wireless headset that offers everything you could want from a pair of high-end headphones.
There are two levels of active noise cancellation, which can be customised through a companion app for the headphones. A slider switch on the headphones lets you quickly move between ambient sound mode, active noise cancellation, and no effect, and the differences in sound are audible and distinct. The ‘Max' level of noise cancellation is effective, but we found it a bit too stark; the ‘Normal' level offered a more comfortable listening experience. Active noise cancellation is good on the whole, but just a bit short of the better all-round experience offered by the Bose Noise Cancelling Headphones 700.
Where the Shure Aonic 50 truly comes into its element is sound quality. With support for all major codecs including advanced options such as LDAC and Qualcomm aptX HD, along with excellent studio-grade tuning, the Shure Aonic 50 is the most analytical, revealing, and detailed pair of wireless headphones we've heard. It's also built beautifully, and offers an exceptional all-round listening experience that combines modern features, technical superiority, and great sound.
Till last year, the idea of good active noise cancellation combined with the true wireless form factor wasn't considered realistic. However, various options have proven that it can be done, including the Apple AirPods Pro. Priced at Rs. 24,900, the Apple AirPods Pro offers effective and highly functional active noise cancellation despite the small size.
All of this is carried out by multiple microphones and Apple's custom H1 chip, which processes data from the microphones to properly cancel out noise. Although the result naturally doesn't come close to the stark silence of the Bose and Shure options, there is an audible reduction in noise which makes this a sensible option given its price and form factor. Another big pro is the transparency mode, which offers the most natural hear-through effect we've heard on any wireless headset.
To top it all off, the AirPods Pro sounds pretty good as well. These true wireless earphones from Apple are responsive, flexible, and consistent when it comes to sound quality, offering good performance across genres and source devices. Some functionality is limited to Apple's own devices, but you can use the AirPods Pro effectively even with Windows PCs and Android devices.
The successor to the Sony WH-CH700N, the WH-CH710N offers effective noise cancellation for less than Rs. 10,000. The noise cancellation isn't anywhere near as effective and stark as with the premium options in this list, but it's entirely usable and functional both indoors and outdoors.
Sound quality on the Sony WH-CH710N is decent as well, and you get class-leading battery life, with the headphones running for over 30 hours with active noise cancellation switched on in our tests. This is our top pick among wireless headphones priced under Rs. 10,000, and good noise cancellation is a big reason for it.
We've limited our picks for this guide to what we consider the best options for active noise cancellation. While there are more affordable options available with the technology as well, we've chosen only the top-rated products in our primary picks, based on reviews and our experiences with them and this technology over the years.
Active noise cancellation is still an expensive technology, and the best options remain relatively pricey as compared to most ordinary headsets. Affordable options do exist, but don't quite offer as good an experience in our opinion, and it may be better to save up and invest in a good option later, rather than simply buy into the technology with a sub-par headset.
Nonetheless, we have mentioned some of the other options in the category below. These may be available at lower prices and could be worth looking at if you're on a tight budget.
Sony WH-1000XM3: Still widely considered among the best wireless noise cancelling headphones around, the Sony WH-1000XM3 is unfortunately dated and not quite the top dog anymore. The Sony WH-1000XM4 is expected soon, and could well match up to the Bose and Shure options when it comes to both sound quality and active noise cancellation.
Sennheiser Momentum True Wireless 2: Purely on musicality and the listening experience, there's no better pair of true wireless earphones you can buy right now than the Sennheiser Momentum True Wireless 2. Good active noise cancellation is an added bonus.
Sony WF-1000XM3: Only recently launched in India, the Sony WF-1000XM3 brings its flagship-level active noise cancellation to the true wireless form factor. There's also a promise of very good battery life with these earphones.
JVC HA-FX65BN: The most affordable option on this list, the JVC HA-FX65BN offers entry-level active noise cancellation for Rs. 4,990. It's basic, but it works just well enough to make a difference to sound quality.
Huawei Freebuds 3i: Priced at Rs. 9,990, the Huawei Freebuds 3i is the most affordable pair of true wireless earphones with active noise cancellation around (that we know of). You also get gesture controls and up to 3.5 hours of battery life on the earphones.
