Overview: The Sennheiser PXC
450 are closed, dynamic, over-the-ear stereo headphones with the latest active
noise compensation technology know as NoiseGard 2.0, designed for use with any
entertainment system, including in-flight audio systems. Passive and active
noise reduction enables you to enjoy music even in noisy environments.
NoiseGard 2.0 Noise-cancellation Technology:
NoiseGard technology 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 optimized 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) for frequencies below 1 kHz. It is of
course also possible to use these headphones passively, without NoiseGard and
When using the PXC 450 headphones, you can
communicate with your friends and family without taking off the headphones via
the TalkThrough function. 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 person's voice is passed on through the
headphones into the your ears in top audio quality.
Diaphragms: The patented Duofol
diaphragms prevent unwanted partial oscillation to provide a
highly natural, lifelike sound quality.
The headphones volume can be adjusted directly on
the headphones from the right earcup's volume controls.
The PXC 450 provides a comfortable fit and high
level of passive ambient noise attenuation thanks to its over-the-earcup design
and padded headband made of top quality materials.
Removable Headphone Cable: The headphone
cable of the PXC 450 can easily be removed and replaced for long service life.
You can also remove the headphone cable to use the headphones as a passive
hearing protector device.
Airline Stereo Audio Adapter: The supplied airline stereo audio adapter allows connection to a variety of
aircraft entertainment systems.
Travel Case: The headphones fold together for
compact storage in the provided case, making them an ideal travel
