The Bowers & Wilkins Px8 are one of the finest examples of B&W's commitment to quality, albeit at a rather inflated price point. Tested at £599 / $699 / AU$1150, the luxury pair go for big money but have the performance to match, offering up outstanding clarity alongside punch, dynamism and a keen sense of musical comprehension. The PX7 S2s are available in grey, black and a really great-looking blue (1). They’re very comfortable and, while you’ll get some ear fatigue after a while, they’re more than comfy enough to wear for several hours at a time… though they do weigh over 50g more than Sony’s WH-1000XM5s. As mentioned by Jennings, the new model has a new app. So those who also might have the older Px7 (or others) will use the old app. The Px7 S2 and Px8 utilize the new Bowers & Wilkins Music App. It is fairly basic, with some customizable features. I find that having so many headphone apps, I have a dedicated folder on my phone for them. Sound Quality: Advantage Bowers & Wilkins, Sorta. The Bose offers bass, mid and treble controls via their app but the B&W does NOT. Regardless of how we adjusted the tone controls of the Bose 700 UC, we felt the B&W PX7 beat them out in sound quality. The PX7s were just more fun and more engaging to listen to. About this item .
