These wireless noise-canceling headphones from Porsche Design and KEF are pricey but last 30 hours

German lifestyle brand Porsche Design and British audio company KEF have released a

new set of wireless noise-canceling headphones that feature a solid 30-hour battery, called Space One Wireless. They cost £350 (about $470) and feature active noise-canceling technology, Bluetooth aptX, 40mm drivers, and a cable with mic for optional listening without battery drain. The companies claim the headphones will last 30 hours even with Bluetooth and active noise canceling switched on. That’s on the higher end of battery life; other cans from Plantronics, Sony, Bose, and AKG last between 20 to 30 hours. The Space One Wireless also feature a lightweight aluminum band with memory foam cups.                                                                                            https://www.theverge.com/circuitbreaker/2017/9/29/16383296/wireless-noise-canceling-headphones-porsche-design-kef
