Sennheiser’s PXC 450 is part of this brand’s high end.  With its closed design and active noise reduction technology, NoiseGard 2.0 (see box), it supposed to offer optimal protection against ambient noise.  In addition, it has a TalkThrough function which enables communication with the outside world without having to take off the headset.  The PX 450 seems to be the perfect solution for music and movie lovers that travel frequently.

Ergonomics:  Opening up the PXC 450’s box we find a very complete bundle.  Besides the headphones, there is a rather attractive semi-rigid black pouch,  6.3mm jack and airplane adaptor as well as 2 AAA batteries.  As for the headphones themselves, there is no hesitation on our part when we say that they are of excellent construction.   Fittings are solid and finishing touches outstanding.  We can only criticize its size and weight which are quite imposing.  Despite this, the headphones sit firmly on your head and they are pleasant to wear – even for several hours (tested and approved!).

Audio quality : In this domain, we fell for the PXC 450 without a doubt.  Overall, sound is very well balanced.  Basses are excellent being clear, varied and have a solid foundation in tracks.  The other frequencies are also well represented.  Nevertheless, if we were to be extremely picky, highs could be a little more imposing.  However, in the end, there is an airy, very pleasant quality to sound which will please even the most demanding listeners (even if there is a slight lack of precision).   Finally, NoiseGard 2.0 proved to be a rather efficient and useful function.
