Dyson followed up its very unique first pair of headphones with an onboard purifier housed in a mask in a more conventional way with the OnTrac headphones. True to the brand, these boasted a unique and customizable design, 55 hours of runtime, and a high price tag of $499.99.

The Dyson airwrap i.d. multistyler and dryer very rarely goes on sale, which makes this Amazon Prime Day deal especially exciting. While the discount is a modest 17 per cent, it still knocks a big £80 off the price. If you’ve been holding out, now’s the time to pounce.
