Sennheiser-PXC450-Noise-Canceling-Headphones

Outstanding sound quality and undisturbed music enjoyment even in noisy environments. The PXC 450 foldable high-end travel headphone with NoiseGard 2.0 active noise compensation reduce annoying outside noise by up to 90 %. A "TalkThrough" function allows you to communicate undisturbed while wearing the headphone. The PXC 450 is a circumaural high-end travel headphone set with NoiseGardTM 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.NoiseGardTM 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. NoiseGardTM actively compensates the noise, based on the physics principle of sound and counter-sound.NoiseGardTM 2.0 has perfected the NoiseGardTM principle thanks to the use of optimised circuitry design and even more efficient processors. It also uses better quality microphones, which enable more sophisticated pick-up of unwanted noise. Specially developed filter algorithms enable improved active noise compensation of up to 90% (23 dB). It is of course also possible to use these headphones passively, i.e. withou
