Sennheiser PXC 450 Noise Cancelling Headphones

The PXC 450 is a circumaural high-end travel headphone set with NoiseGard 2.0 technology and TalkThrough function for the best possible attenuation of ambient noise. The PXC 450 enables an unprecedented sound experience for people on the move, thanks to its adaptive baffle damping in combination with the patented Duofol diaphragms, which prevent unwanted partial oscillation and thus guarantee a highly natural, lifelike sound quality. NoiseGard is an active noise compensation system which Sennheiser originally developed for use by pilots, who have to rely on good sound quality and efficient protection against ambient noise even in high-noise environments. NoiseGard actively compensates the noise, based on the physics principle of sound and counter-sound.
