Reduces up to 90% of Ambient Noise
The PXC 450 is a premium circumaural headphone featuring Sennheiser’s exclusive NoiseGard™ 2.0 active noise compensation system, which effectively reduces up to 90% of ambient noise. The extremely comfortable headphones offer audiophile-grade sound combined with a foldable construction for maximum enjoyment and convenient storage.
"A nice feature is the button on the right can that quickly deactivates noise cancellation so that you can talk to people without having to take the headphones off (and subtly remind them that you'd like to go back to your Abba groove now, please and thank you)," reports Emru Townsend in his January 09, 2007 review for PC World magazine.

We consider the PXC450’s overall look and feel to be at least a couple of steps up over lower-cost alternatives,
Just one AAA battery is all it takes for up to 16 hours of serene enjoyment. The PXC 450 also functions as a passive headset when used without batteries, so audio always works.
Adaptive baffle damping and patented Duofol diaphragm technology deliver pristine audio reproduction.
