Seriously, why aren't you buying the best headphones in the world at this price?

Sometimes, writing up deals on Prime Day can be an involved task, with much research and balancing whether something is actually a good deal.  This is not one of those moments.

The Sony WH-1000XM4 are quite simply the best pair of noise-cancelling headphones money can buy these days, and they're the cheapest price we've ever seen for them at Amazon for just $298... with a free gift.

Not only are they our pick of the best headphones we've tested this year, they come with an inexplicable $25 gift card on Amazon. So you can buy other things, admittedly, but we have many ideas on how to help you with that.

Why are you still reading this? Seriously, if you're in the market for excellent headphones, then these are the ones to buy - right this very second. (Not in the US? Scroll down for the best deals in your region.)

If you're not bothered about the free gift, or just don't want to buy from Amazon, Best Buy have matched this Prime Day deal with its own discount, also cutting $51 from the price of the Sony WH-1000XM4.

These Sony cans are the best noise-cancelling headphones you can buy – and having only launched fairly recently, this $51 discount is a real bargain. If you're still wondering whether to buy these headphones... don't, just do it.

Sony WH-1000XM4 Wireless Headphones: $349 $298 at Best Buy
You can take advantage of that stellar discount at Best Buy too, which has also slashed the price of the noise-cancelling headphones by 15% as well, but lacks the gift card you can get at Amazon.

This Sony WH-1000XM4 deal comes as a bit of a surprise, considering the headphones were only released back in August. 

These class-leading cans deliver excellent adaptive noise-cancellation and fantastic sound quality, with the ability to upscale your compressed digital music files automatically. 

Multipoint pairing makes it easy to switch Bluetooth devices, while an auto play/pause sensor means the headphones will stop your music if you remove them from your head.

If you need to have a quick conversation, a new Speak-to-chat feature automatically reduces volume when the headphones detect the sound of voices – no need to take your headphones off when ordering a coffee. If it's taken this long to be convinced though, perhaps you're looking for true wireless earbuds instead? The Sony WF-1000XM3 have also been given a hefty discount for Prime Day:

Sony WF-1000XM3 Wireless Earbuds: $229.99 $178 at Amazon
Save $50 on one of the most popular premium wireless earbuds today at Amazon. Featuring industry-leading noise cancellation and fantastic battery life, the Sony WF-1000XM3 have consistently ranked as TechRadar's favorite pair of wireless earbuds. Subsequently, they're a great buy but act quickly if you want to grab them at their lowest price.
