About the Sennheiser PXC 450

Block out busy sounds

Get relief from the din of travel with Sennheiser's PXC 450 noise compensation headphones. These over-the-ear headphones use active noise cancellation technology to reduce external sounds, such as airplane engine roar, so you can listen to your music at lower and safer volume levels. Tiny microphones built into the earcups pick up the sounds of your environment. Advanced circuitry then creates a signal that "cancels out" much of this external noise without affecting the sound of your music or movie soundtrack. A convenient "TalkThrough" button lets you carry on a conversation — such as responding to a flight attendant — without removing your headphones.

Generously padded earcups and headband lets you wear the headphones comfortably hours on end — great for extended trips. The PXC 450s fold together for compact storage and fit into the provided soft belt pouch for convenient travel.

From the review Sennheiser PXC 450 headphones: Quiet and comfortable — even at work

"It wasn't until I put [the PXC 450s] on that I became aware of just how much office noise I had gotten used to. They also performed well as headphones, delivering my music with a full, detailed sound. And the PXC 450s were so comfortable I sometimes forgot I was wearing headphones — until I realized I could barely hear my coworker. Thank heavens for that talk button!"

Product Research

Features

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 without batteries.

TalkThrough Function: 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.

Volume Control: The headphones volume can be adjusted directly on the headphones from the right earcup's volume controls.

Comfortable Fit: 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 accessory.
