Overall the Bowers and Wilkins P9 Signature has a very versatile frequency response. The accent is tilted towards the warm but there’s plenty of detail to be had. Bass: Higher frequencies are well balanced with the rest of the presentation and lead to what most will think of as a comfortable sound. Detail is not sacrificed however and as with the midrange, there is a certain crispness here which grabs the attention. Having said that, the P9 is on the forgiving side when it comes to older recordings, or those whose production might leave something to be desired. Soundstage & Separation:

Here there is a nice amount of clarity and presence giving crisp directional cues and harmonics. Space is there in spades and there is no danger of congestion with more complicated or busy passages. Treble: Works with AirPods Pro (2nd generation) with the latest firmware when paired with a compatible Apple device with the latest operating system software. Isolation on the P9 is fairly low; when tried here in the office with no music, the headphones allow pretty much everything through. With music playing, this is of course mitigated against but still those distracting exterior sounds can be a problem; especially during those quieter passages in classical music, for instance. AirPods (3rd generation) are sweat and water resistant for non-water sports and exercise, and are IPX4 rated. Sweat and water resistance are not permanent conditions. Requires an iCloud account and a compatible Apple device using the latest operating system software.

Soundstage is impressive; with good width and depth. It’s easy to pinpoint individual instruments and the instruments themselves are very nicely rendered thanks to the clear midrange and treble, enhancing the 3D effect. MagSafe charging requires a compatible MagSafe charger. Wireless charging requires a Qi‑certified wireless charger. AirPods (3rd generation) charging case also works with the Apple Watch charger or Lightning connector. AirPods Pro (2nd generation) charging case also works with the Apple Watch charger or USB‑C connector. With the right adjustments, clamping force is distributed equally between headband and earpads, and the earpads have enough give in them for glasses to be worn with no trouble or discomfort.
