Sony’s WH-1000XM4 headphones are still among the best noise-cancelling cans we’ve ever tested. If you’ve been looking to pick up a pair for yourself, Amazon’s surprise sale has the Sony Bluetooth headphones marked down to $198 — their lowest price ever.

For reference, these top-rated headphones are regularly $348+ so the new deal saves you a whopping $150 off the top-rated cups. This makes it a great time to grab these headphones either for yourself or as a great gift for music lovers or frequent travelers.

The WH-1000XM4s stood out to us for three reasons: Its top-notch active noise cancellation, excellent audio quality, and comfort. Sony has put a lot of effort into making sure its noise-cancelling headphones matched (or exceeded) the performance of companies like Bose, and it largely succeeded. These headphones can block out train, plane, and office sounds without requiring you to crank the volume past 70% in most cases. If you’ve traditionally had trouble sleeping during air travel, the WH-1000XM4s are a game changer.

Naturally, the 1000XM4s also sound excellent, delivering crystal-clear audio right out of the box, but you can adjust the way they sound using Sony’s Connect app, which is available on iOS and Android. The app also gives you some control over their noise-cancellation settings, and whether to turn on the “adaptive sound control” feature, which allows the headphones to adjust how they sound based on your location.

Over-ear headphones have a tendency to weigh your head down, especially during extended listening sessions, but the WH-1000XMs avoid this issue because of the amount of padding Sony used on the earcups and headbands. They’re still heavier than a pair of earbuds or on-ear headphones, but you shouldn’t experience discomfort when wearing them for long periods of time.

Finally, the WH-1000XM4s get up to 30 hours of playtime per charge, more than enough to get you through a work day, continental flight, and several additional hours of music listening. The amount of playtime you actually get will depend on how long you keep active noise cancellation enabled and your listening volume. If you’re used to the five or six hours that most true wireless earbuds offer, the WH-1000XM4s will feel like a breath of fresh air.

While Sony unveiled their WH-1000XM5 headphones last year (currently available for $328 on Amazon), the XM4 have many of the same features — and for a much lower price.

Don’t just take our word for it: these noise-cancelling headphones have a 4.6-star rating (out of five) from more than 56,000 reviewers online. More than 82% of shoppers give the WH-1000XM4 headphones a full, five-star review. They are also rated as an Amazon number one bestseller online.
