Amazon is delighting us with substantial discounts on Sony's two most recent ANC headphone models. When it comes to bang for your buck, the deal on the previous WH-1000XM4 appears to be the most appealing.

Full price, the WH-1000XM4 aren't far off from their more expensive cousins. They have an RRP of $349, around $50 lower than the XM5. Generally, however, you'll find the older model at lower prices, on account of their age — usually under $300. For that price, you're not going to find a better pair of over-ear noise-canceling headphones.

To sum up, the WH-1000XM5 headphones boast a first-rate noise cancellation mode, full sound, excellent sound customization features and a comfortable fit, making them a more than worthy purchase at a Prime Big Deal Days discount. We recommend snapping up a pair while the sale lasts!
