The review below will show you the full set of features that put PXC 450 into the premium class for noise cancelling headphones.

Comfortable Design:

Sennheiser have put a lot of effort into the design of these headphones so that they are durable while still being comfortable to use. The thick but soft padding on the headband and top quality ear cup cushions means you could effectively wear the headphones for hours continuously . They are very sleek in looks and don’t have that bulky look most cheaper headphones have. It comes in a very classy color of silver or charcoal black. In terms of sound engineering design, the PXC450 has some remarkable integration of Sennheiser’s audio technology which make it a top product for noise cancelling as well as giving the best in audio sound.

Supreme Ambient Noise Reduction:

As previously mentioned, the Sennheiser’s exclusive NoiseGard 2.0 technology, which effectively reduces up to 90% of ambient noise. It also has a active/bypass mode which can switch the headphones function as a noise cancelling or just a closed-back audiophile. In addition, Sennheiser have taken things a step further by integrating its very innovative TalkThrough technology which still allows the user to talk actively with others without any need to take off the headphones. So any loud background noise will be filtered out while voices are still passed on through the headphones without any distortion or loss of quality.

Premium Sound:

Sennheiser use their patented audio production technology with the adaptive baffle damping along with Duofol diaphragm to give you a greater quality in sound than its competitors. It’s certainly an audio listening experience that you just can’t enjoy with cheaper models. In fact the quality of sound so good that it will brutally highlight any lower bit rate ripped MP3 recordings which are usually a lower quality that normal headphones can’t pick up any shortcomings. Any high quality recordings of MP3 audio will sound like they are coming alive and sound very clear and crisp. Its advised you rip all your CDs at the higher bit rate when using these headphones.

Premium Quality Build:

You can tell from one look at the Sennheiser PXC 450 headphones that they have been built to be very strong. The plastics and components (such as a thick cord that isn’t flimsy like a few other brands) are all of high quality which mean you are getting a very durable and strong product. It’s going to be hard to break anything on them by accident. While its solidly built there is still a nice modern oval shaped sleekness about the PXC450 and still comes up as amazingly light in weight. Also the quality of material in the padding for the headband and ear cushions makes it all feel that you are using a set of headphones that are built for luxury living.

High Portability:

Because of the foldable design, the Sennheiser PXC 450 noise cancelling headphones are actually very portable and make them very compact. This is ideal for travelling around as you can fold them up into the carry case which then slips nicely into any carry-on bag or suitcase.
