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.

Don’t miss the Sony WH-1000XM4 wireless headphones at their lowest-ever price ahead of October Prime Day. Joseph Green is the Global Shopping Editor for Mashable. He covers VPNs, headphones, fitness gear, dating sites, streaming services, and shopping events like Black Friday and Prime Day.

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.
