Engineered by Masters of Sound.

Optimised Cabinet.
P9 Signature's elegant earcups contain sophisticated acoustic cabinets perfected using Finite Element Analysis. Using composites and aluminium 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.
