The system is based on microphones that “listen” to the sounds outside and inside of the earphone, an ANC chipset inverting the soundwaves and a speaker inside the earphone cancelling the outside sound by the neutralising soundwaves. A bit like taking +2 outside and adding -2 inside to make zero.
Active noise cancellation can be processed through the ANC chipset using either:
Mark Levinson No. 5909: The No. 5909 are premium audio brand Mark Levinson's first headphones and, yes, they're really expensive at $999. But they're also really good. They have a sturdy design without managing to feel hefty on your head (read: they're substantial but not too heavy) and they're comfortable to wear over long periods thanks to their nicely padded (and replaceable) leather-covered earcups and headband. Read our Mark Levinson No. 5909 hands-on.
Focal Bathys: French audio company Focal is known for its high-end speakers and headphones. You might call it the Bowers & Wilkins of France. And now it's finally done what a lot of high-end audio companies have had to do in this age of on-the-go wireless music listening: make active noise-canceling Bluetooth headphones. These $699 cans sound fantastic and are great overall but their noise-canceling is fairly light, so don't buy them for their ANC.
Master & Dynamic MW09: Master & Dynamic headphones and earbuds have always featured unique, eye-catching designs that include premium materials like aluminum, sapphire glass and Kevlar. Its latest MW09 flagship earbuds look pretty similar to its earlier MW08 buds, but have some upgrades on the inside that deliver better performance, particularly when it comes to battery life and noise canceling (it's now very close to what Bose and Sony offer, though not quite at their level for ANC).
Samsung Galaxy Buds 2 Pro: The Galaxy Buds 2 Pro offer improved noise canceling along with very good sound and voice-calling performance, plus support for high-resolution wireless audio streaming if you're a Galaxy device owner with the right setup. That said, their biggest upgrade may be their new design and smaller size, which make them a better fit for more ears. Aside from their somewhat high price tag, their only drawback is that some of their key features only work with Samsung Galaxy devices.
Beats Studio Buds Plus: Alas, for those of you who bought the original Beats Studio Buds, which remain on the market for now, I'm sorry to report that these new Plus buds are significantly improved, with better sound, noise canceling and battery life. Additionally, they now deliver top-notch voice-calling performance.
Beats Fit Pro: While the Beats Fit Pro technically aren't AirPods, they're built on the same tech platform as the AirPods Pro (yes, Apple owns Beats). Unlike Beats' earlier and less expensive Studio Buds and new-for-2023 Studio Buds Plus, the Beats Fit Pro include Apple's H1 chip and have most of the AirPods Pro's features, including active noise canceling, spatial audio and Adaptive EQ. I'd venture to call them the sports AirPods you've always wanted.
Technics EAH-A800: There's a bit of an old-school vibe to the Technics EAH-A800 -- and it's not just the Technics brand, which Panasonic resurrected in the last few years. Their design is something of a throwback but the headphones are comfortable and both fold up and fold flat. They feature a big, energetic sound with powerful bass and good detail (however, they take a day or two to break in).
Technics EAH-AZ80: Panasonic has done a nice job of creating an all-around top-performing set of buds that offer an improved fit with terrific sound, good noise canceling and a robust feature set.
Sennheiser Momentum True Wireless 3: Featuring excellent sound, improved noise canceling and voice-calling performance as well a smaller, more refined design that includes stabilizing fins (so the earbuds stay in your ears more securely), the Sennheiser Momentum True Wireless 3 are among the best true-wireless earbuds, giving the Sony WF-1000XM4 a run for the money. Read our Sennheiser Momentum True Wireless 3 review.
Sennheiser 450BT: Sennheiser updated its well-regarded 4.50BTNC noise-canceling headphones in 2020. The new headphone model is called the 450BT and it has some notable upgrades, including better battery life (up to 30 hours with noise canceling on), USB-C charging, Bluetooth 5.0 with aptX support for devices like the Samsung Galaxy smartphones that support it and more comfortable earpads. The 450BT noise-canceling headphones list for $200, but usually cost around $150 although they have dipped to as low as $100 in flash sales (they're a good value at that price).
Google Pixel Buds Pro: The Pixel Buds Pro are Google's first earbuds to feature active noise canceling. While it's nice that they finally have a feature that a lot of true-wireless earbuds have had for a while, what ultimately sets the Pixel Buds Pro apart and makes them worth considering -- particularly for Android users -- is their distinct design and winning fit. That helps enhance their performance on both the sound quality and noise-canceling fronts. While not quite elite for voice-calling, they also performed well as a headset for making calls.
