My head is nestled in a pair of Onyx Black Bowers & Wilkins Px8 S2 over-ear noise-canceling Bluetooth headphones, “Retrograde” by James Blake pouring in. Inside, Bowers & Wilkins is consecrating the Px8 S2, the company’s upgraded flagship wireless headphones. And this is doubly fitting for the Px8 S2: headphones, like guitars, are a familiar source capable of releasing fresh expressions when revisited. Put the Px8 S2 against the Px7 S3, and the S2 showcases a fatigue-free composure. At this moment, the Bowers & Wilkins Px8 S2 headphones stand out for an undeniable command of texture and timing.
