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.NoiseGard 2.0 has perfected the NoiseGard 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. without NoiseGard and without batteries. Users of a PXC 450 who wish to communicate with their neighbours can do so without taking off the headphones when the TalkThrough function is activated professional quality microphones mounted on the outside of the headphones pick up all acoustic signals in the immediate vicinity. Unwanted background noise such as the sound of the engines on a plane is filtered out electronically to a great extent so that only the neighbours voice is passed on through the headphones into the users ear in top audio quality. The PXC 450 is foldable and is supplied complete with practical transport case 2 AAA batteries and audio adaptors double mono and 6.3mm. Volume control integrated in the headphones and a single sided detachable and replaceable cable ensure maximum convenience for the user.Delivery Includes PXC 450 high end travel headphone Transport Case 2 Audio Adapter In flight Entertainment and 63 mm 2 AAA batterys
