VERDICT
The Bower & Wilkins P9 cans look and sound great, but they’re aimed more at mobile use rather than home listening and are rather pricey. The Sennheisers, on the other hand, offer great value for money but they’re just a little more ‘ordinary’ in terms of design and build. Both the Audio-Technica and Quad cans offer great definition, but sound quite different: the Audio-Technicas are light and delicate, while the Quads sound warm and rich. The AudioTechnicas fared slightly better with bass-heavy styles, but we’re sure the Quads would catch up in time and that, coupled with their sturdier build, makes them our winners, by a hair.
