Sennheiser PXC 450 Flight

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.

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 neighbour’s voice is passed on through the
headphones into the user’s 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.
