The same team behind the 800 Series Diamond loudspeakers found in Abbey Road Studios have focused on a much smaller space: your ears. Bowers & Wilkins' PI7 & PI5 are the company's first true wireless models. The PI7 includes more advanced features, including a 24-bit connection, Qualcomm aptX Adaptive technology, Adaptive noise cancellation with six microphones, and Dual hybrid drive units, all of which combine to create immersive, detailed sound. The smart charging case of the PI7 supports fast wireless charging and can also do audio retransmission, connecting to in-flight entertainment and gaming systems such as the Switch via a USB-C to 3.5mm cable and passing the audio to the 'buds. Battery life is four hours per earbud, with an additional 16 hours from the charging case, and they offer IP54 water resistance for protection against splashes. The PI5 shares a similar design but lacks the dual hybrid drive units, 24-bit connection, audio retransmission, and six microphones of its more expensive stablemate. Both are available now in white or charcoal.
