Keep Noise Away with Sennheiser's New PXC 450 Headphones

Sennheiser, one of the best known producers of professional audio equipment, recently introduced a new pair of high-end headphones boasting some of the company's most exotic technologies.

The PXC 450 is presented by Sennheiser as a "circumaural high-end travel headphone set with NoiseGard 2.0 technology and TalkThrough function for the best possible attenuation of ambient noise". I see this whole noise cancellation thing as a double-edged sword. If you're on a plane or in another vehicle and there are no risks, it's great; but if you're walking, crossing the street or driving your car, this can cause a lot of problems since you will be completely deaf to the outside noises.

Sennheiser achieves noise cancellation with two components. The first is the "adaptive baffle damping in combination with the patented Duofol diaphragms" and the second is the Noise Guard 2.0, which is an active noise compensation system.

Let's see what the producer has to say about its new technology: "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)". Keep in mind that this technology relies on power to function, which means that you'll always carry 2 AAA batteries. The headphones can work without the batteries, but you won't have the sweet NoiseGard 2.0.

The microphones fitted on the set are also used for the TalkThrough function that enables users to hear somebody without taking their headphones off. What's more, when the TalkThrough is activated, any background noise is filtered out electronically.

High-end stuff costs and the PXC 450 is no different, since not everybody can afford the $600 price tag; however, what you get is excellent audio quality and advantages you don't have with regular headphones.
