Sennheiser has released yet another range of noise-cancelling headphones, tailor made for frequent travelers and fliers. The Sennheiser PXC 450 is one such product that promises up to 90% ambient noise cancellation. The product comes with the new NoiseGuard 2.0 technology, the latest in the noise compensation technology. It also includes the Duofol diaphragm technology and adaptive baffle damping, said to enhance audio quality and experience. It is fuelled by a single AAA battery, which provides working time of around 16 hours. It comes with adequate cable length, and a transport case, which is an absolute requirement. The in-flight entertainment adapter for air travel is very useful.

At the outset, the PXC 450 satisfies most of the requirements of someone looking to enjoy good music while travelling, without damaging their eardrums. Its noise cancelling is top-notch, and as seems to be a promise that has been kept. There is extra padding given to the ear cups, which not only makes the headphones more comfortable, but also enables passive noise cancelling. In addition, the softness of the ear pads adds to the comfort. I have not experienced any heating up that generally happens with other headphones that are in a similar league as these. The build of these headphones is solid and sturdy. The parts are of excellent quality, the plastics are strong and the cord is thick enough.

One other highlight of the PXC 450 is the TalkThrough technology. This unique innovation enables communication with neighbors without removing the headphones. When it is activated by the push to press of a button by the user, all other unwanted noise in the environment, apart from the neighbor’s voice is cancelled, enabling top quality communication. I have found this feature to be particularly useful while communicating with airhostesses and flight attendants. Its sound quality is wonderful. There were parts of a song I recognized and appreciated only after listening to them with these headphones! The built-in amplifiers, which are a common feature of any noise cancelling headphones, are made use of in a novel way, the volume of which can be controlled by the user. The audio also works in the passive mode, and hence doesn’t always require batteries.

One small drawback of the PXC 450 is its size. For over the ear headphones, and in comparison to their counterparts, these are fairly small. They can also be folded. However, they are a little too big for travel. The travel case that comes along with the headphones is ideal for its storage but is larger than most of its counterparts. Surprisingly though, it is relatively lightweight and makes up for the relatively larger size of the headphones, making them less cumbersome to travel with. The bass is not as much as powerful as some of Sennheiser PXC 450’s counterparts, but is not something that affects the sound quality adversely. Also, the PXC 450 might seem to be a bit on the expensive side. They might not be the cheapest in the market, but nor are they the most pricey. However, it is not affordable by everyone as not everyone would be willing to spend $200 to $275 on a pair of primarily noise cancelling headphones. If they fall within your price range, then they are definitely worth every penny.
