We're now right in the middle of Amazon's Prime Day event, and after sifting through thousands of "deals" (some great and some not-so-great) we can officially say it: Prime Day is actually delivering the goods this year.

Bose Certified Refurbished products are thoroughly inspected, tested, and serviced to meet strict Bose sound quality standards – the same as a new product. Appearance is closely examined; products occasionally have minor, nearly imperceptible blemishes. All Refurbished products have the same warranty as new products.

Let's start with what's easily the best offer of the lot: the Sony WH-1000XM4 Wireless Headphones for $185.24 (was $348). This is the closest these fantastic headphones have come to the previous record-low price in months – and they're only a few bucks more than that best-ever deal.
