Bowers & Wilkins PX vs Sony WH-1000XM3 Wireless

The Sony WH-1000XM3 Wireless are slightly better wireless noise cancelling headphones than the Bowers & Wilkins PX Wireless. The Sony are a lot more comfortable than the B&Ws out of the box. They're lighter and have better-padded ear cups that do not clamp your head like the PX. The Sony also have a longer battery life, a better noise cancelling performance and a more customizable app that makes them a bit more versatile for different listeners than the PX. The PX, on the other hand, are much better-built, look a bit more premium, and feel more durable. They also leak a less at high volumes, so they're a bit more suitable for noise-sensitive environments like using them at the office.
