Oops! Did Amazon make a mistake? Sony XM4 headphones hit their lowest-ever price on Prime Big Deals Day
Get them while stocks last

Strange goings on over at Amazon. It's Prime Big Deals Day but it seems like one deal was too big to be true.
The five-star Sony WH-1000XM4 headphones appeared online reduced from their original price of $350 to just $129 – but you'll have to take our word for it, as the deal has now been removed. And we're not surprised, as we've never seem them drop anywhere near that low.
However, you can still pick up the XM4 headphones for just $198, which is still a 43% saving and still lower than previous Prime Day and Black Friday sales.
The XM4 headphones have been succeeded by the XM5 over-ears but they remain a great pair of noise-cancelling wireless headphones. In fact, they are probably all the performance most people need. So you can still pick up a great bargain – just not quite as great as briefly appeared earlier on Amazon.

The five-star WH-1000XM4 were, until the recent launch of the WH-1000XM5, Sony's top-of-the-range wireless noise-cancelling headphones. With a winning combination of stunning sound, 30-hour battery life, intuitive controls and adjustable noise-cancelling, the XM4 are hard to beat, especially when they are so heavily discounted.
The XM4 are every bit as comfortable as their predecessor, the WH-1000XM3, but introduce new useful features that elevate the user experience. ‘Speak to Chat’, for example, allows you to talk to someone while the headphones are still on your head.
More importantly, the headphones dish up an impressive hike in sound quality over the XM3. Their sense of musicality and enthusiasm remains as addictive as ever, but there are also big improvements across the board.
