Warranty Period: 1 year Sold as: Single Unit


50 years of audio excellence

P9 Signature is conceived by our engineering team in the Steyning Research Establishment in West Sussex, England. Founded by John Bowers, SRE is the heart of Bowers & Wilkins and the mind and soul that creates the products people love.

Engineered by masters of sound

Optimised cabinet
P9 Signature's elegant earcups contain sophisticated acoustic cabinets perfected using Finite Element Analysis. Using composites and aluminum this optimised acoustic environment enables the drive unit to do its job of rendering your music with total precision.

De-coupled headband
P9 Signature's headband cleverly decouples each earcup. This stops unwanted vibration transmitting between each earcup and the headband. This removal of distortion is one of the reasons P9 Signature is so clear and open sounding.

Perfect piston
Our engineers developed an advanced new drive unit for P9 Signature with a clever suspension system that enables it to provide precision at high frequencies and compliance for great bass

Sound that exceeds all expectations

We've aligned the drivers in the P9 Signature to provide a more natural experience. You will hear stereo more like it sounds in real life; aligned in front of you rather than to the side.
