The P5's weren't in need of fixing. Their blend of style and sound were already a hit. Unless, of course, you're the type of person that doesn't like wires (Hint: we're all that type of person). The Bowers & Wilkins P5 Wireless Headphones offer outstanding sound quality without the wires. Tuned by the engineers at Abbey Road Studios, they use drivers with traditional speaker-like diaphragms for more precise sound, rechargeable batteries with up to 17 hours of playback life, and aptX technology for the best possible wireless audio reproduction.
