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.

    Lasted me quite awhile

    My parents got these for me when I turned 15 and I fell in love with them. The big problem for these headphones is the battery with age. It wears down quickly, but still lasts a few weeks before you have to change the batteries


    The noise cancelling is great. Blasts when you want it to blast (be careful though)


    When it gets older, the battery wears down quickly, fairly easy to break. This only happens if you have them for awhile


    Noise cancelling and hearing protection


    I would recommend this to a friend.

    Inside parts don't last.

    Switch inside the headphone was faulty. It has taken 5 weeks to get any repairs done as they didn't have the parts in Australia.


    Comfortable, Stylish


    Flimsy Construction
