Noise-cancelling headphones have become almost an essential everyday item for many of us, whether they're used to isolate you on your morning commute or drown out the drone of an aeroplane jet engine.
With so many pairs now being available, finding the best pair for your ears is no easy task. Some pairs will have more effective noise cancellation, while others will sound better - so finding the middle ground can be tricky.
We've rounded up our favourite pairs and picked out what we believe to be the best pair money can currently buy, to make the decision whole lot easier.
Sony has updated the 1000X headphones three years in a row, taking an approach as aggressive with product launches as it is with cutting out external noise. Design tweaks add quality and refinement to these headphones, while a new-and-more-powerful chip provides the grunt to cancel out more noise.
The results are sensational, with the 1000XM3 not only sounding great as a set of headphones, but also being some of the most effective at combatting external noise through more selectable levels.
These cans also offer Google Assistant control with a button press - to give it commands or ask it questions - but we fon't think it's very well implemented, which is about its only weakness in this smart pair of headphones.
Bose QuietComfort 35 II
Think of noise-cancelling headphones and chances are you'll think of Bose. The company's QuietComfort range is known the world over for being the crème de la crème in noise-cancellation technology. The QuietComfort 35 II is the last in the line of the company's ANC arsenal - the Headphones 700 will replace them - but the first to go wireless in the process.
The second-gen QC35 is exactly the same as the original pair that wowed us in 2016, save for a new dedicated button for launching Google Assistant. This new button lets you launch Google Assistant and ask it questions, or basically any other command you'd ask Google Home.
While we can really sing about the noise-cancellation offered by this Bose pair, we feel the sound quality lacks a little compared to the pair from Sony (above) and the build is a little lighter and more plasticky than some. Nevertheless, they're still a fantastic pair of noise-cancelling headphones - and the choice for travellers given the light build and strong cancellation.
Bowers & Wilkins PX
Bowers and Wilkins is no stranger to the audio game; the British-based company has been going since 1966. So when we heard it was developing its very first pair of wireless active noise-cancellation headphones, our ears certainly pricked up. When we actually got them onto our ears, our expectations were exceeded far beyond anything we could imagine.
The PX headphones looks stunning - we really do love the blue and gold finish - and they sound even better. We already expected a great sounding pair of headphones, but we weren't prepared for just how well the noise-cancellation would work, nor the abundant features B&W has thrown into them.
We love the sensors that automatically pause or stop the music you're listening to entirely depending on how you wear them, and the way you have complete control over the amount of ambient sound to let in via the app. They're an incredibly great rival to the class-leading Sony (up top), in terms of features, effectiveness and price. We would still say Sony has the edge over B&W, but not in terms of build quality.
Beats Studio 3 Wireless
The Beats Studio 3 Wireless are likely to appeal to iPhone owners more than those using an Android phone, only because they're the latest pair to benefit from Apple's W1 chip (which has been replaced with the H1 chip, moving forward). This means these cans automatically try to pair with an iOS device when within distance, and once paired are available to instantly connect to from all other Apple devices using the same iCloud account.
The Studio 3 Wireless have some very clever noise-cancellation technology onboard too. It constantly measures the sounds around you - up to 50,000 times per second - and adjusts both the noise-cancellation and sound profile accordingly, to make sure you're getting the most effective sound blasted into your ears.
The sound is less bass-tactic that you might expect from this headphone company too, yet still impactful, while the battery life just goes on and on and on.
B&O BeoPlay H9i
The B&O BeoPlay H9i is one of the more expensive pairs of noise-cancelling headphones to grace our ears, but in return these cans provide a supreme level of comfort, thanks to high-quality materials.
To complement the fantastic build quality is incredible sound quality - and these headphones evolve themselves beyond the original H9s. The H9i has boosted the noise-cancelling ability, while shrinking the ear cups a little, thus making them a little more practical.
With a wealth of competition at lower prices, the B&O BeoPlay H9i need to do a lot to justify their asking price, but we'd spend the extra for the build and comfort. If you want really strong noise-cancelling, however, then look to the Bose (above) for that totally 'locked-in' quality.
Microsoft Surface Headphones
Ok, so we don't like the big Windows-like logos on the side of these headphones... but Microsoft has otherwise done a stellar job with its first bash at a pair of headphones, thanks to a variety of great features.
First up, these cans are comfortable on the ears for long periods of wear. Second, the two earcups rotate - the left for noise-cancelling level, the right for volume - which gives a great, natural way to control the headphones without needing any unsightly or hard-to-locate buttons.
But there are imperfections: we'd like to see more exciting colours and design, along with some stronger ANC at the maximum level to rival the Bose (further up), plus a greater variety of ANC types like the Sony (up top). That said, if you want comfortable, long-lasting and easy-to-control ANC headphones then don't overlook Surface - whether or not you use a Microsoft laptop/2-in-1 or not!
Bose QuietControl 30
Noise-cancelling isn't solely reserved for over-ear headphones, as we're now seeing the technology finding its way into in-ear models too. The best pair we've come across so far is the Bose QuietControl 30. Not only do these in-ears exhibit the same superb sound profile as Bose's other headphone models, but the noise-cancelling is adept too.
You can fine-tune just how much external sound you want to block out using the companion app, so if you're on a train, for example, you'll want the tech to be turned up to the max, but if you're cycling and you want to be aware of your surroundings then you'll dial it down a little to let some sound pass through. In practice, it works tremendously and is the best example of noise-cancelling we've come across in a pair of in-ears.
Some may find the neckband design a little irksome, but given enough time to adapt to this design, we think the Bose makes for a near-perfect pair of headphones to carry around with you.
The Libratone Track+ offer a neckband-style set of headphones which are lightweight, smart and brilliantly designed. While sound quality and noise-cancellation skills are common to all the headphones on this list, it's the brilliant design that's worth paying attention to.
Perfectly balanced is how they are pitched and that holds true, so whether you're wearing these on your commute, or running a 10k, these headphones stay comfortably sitting where they are supposed to.
In addition, the noise-cancelling is pretty good, offering different levels and, via the app, you can have this automatically change based on your motion. The result is a very effective and comfortable set of headphones, as competent on your travels as on the running track.
Sony has applied its audio expertise to noise-cancelling in-ear headphones too. We've seen what the company can do with a pair of over-ears, so we had mighty high expectations for the entirely wire-free in-ear model.
These wireless in-ears deliver a well-balanced sound that's neither too bassy nor too bright; we found it to be just right. The noise-cancellation is just as accomplished, too, effectively blocking out the general hum drum of everyday life, as well as aeroplane and train noises.
Battery life isn't what we'd call amazing, but wire-free in-ears as a category suffer as a whole. Fortunately, the case doubles up as a charger.
We would say the Bose QC30 offer more effective noise-cancellation, but the Sony WF-1000X aren't trailing too far behind.
If you're more concerned about battery life but still want the same winning combination of Sony sound and noise-cancellation, look no further than the WI-1000X. These in-ears, like the Bose QC30, utilise a neckband design - which is very comfortable and one you won't notice during listening sessions.
Like their WH- and WF- siblings, this WI- pair has sensors onboard to detect what you're doing or where you are and adjust the sound profile and noise-cancellation accordingly. There's also high-resolution audio support if you have such files, but if you don't then these in-ears will upscale, while equaliser settings can be adjusted within the companion app. Google Assistant will come in a future update too.
Top this off with a 10-hour battery life and you have yourself a pretty darn good pair of noise-cancelling in-ears, one that we wholeheartedly recommend if you're ok with a neckband design.
