In the quest of creating the best active noise canceling device, Sennheiser pxc-450 noiseguard active headphones was designed to deliver sound minus the unwanted background noise. This made it even more appealing among business travelers, frequent flyers and holidaymakers, who sure will be delighted to experience the difference in sound quality that Sennheiser offers. Also, to all video and movie buffs, watching your videos and movies in a portable DVD player will be better appreciated with this circumaural pair of ear pads, which does not only cancel background noise but also deliver unprecedented sound quality. The detailed and clear sound of pxc-450 is well balanced across the spectrum.

The nominal impedance of portable device headphones is meant to be less than 64 ohms. This gives the capability to produce great sounds at a reasonable volume. On the other hand, professional headphones are given about 300 ohms to get less volume with higher impedance phones. Now, pxc-450 uses these different factors to deliver excellent sound presentation. Its adaptive baffle damping capability guarantees consistently good bass reproduction. Its patented Duofol diaphragms effectively prevent unwanted partial oscillation on the sound waves. This way, it generates crisp and crystal clear sound.

The secret to Sennheiser pxc-450 noiseguard active headphones' noise canceling features lies on its NoiseGard noise compensation technology, which neutralizes unwanted noise such as engine noise, conversation and other pesky daily life noise. It has a tiny microphone mounted on the outside of the headphones to pick up ambient noise. Then, its processor calculates and superimposes the relevant phase-inversed sound signals that it picks up. As a result, the two acoustic signals effectively cancel each other and ambient noise is reduced if not eliminated. This way, Sennheiser's pxc-450 has established its 90 percent noise reduction rate.

The product is actually given the NoiseGard 2.0 system, which gives more advanced noise processor efficiency than the pxc-350 model. This optimizes its capacity to ensure virtually unrestricted sound experience even in noisy or high-noise environment. Also, the efficient miniature microphone in pxc-450 records the immediate noise from the immediate environment, which distinguishes between simple noise and the voice of the person sitting next to you. Along with its audio controls, the voice of the person next to you may be allowed to pass into your ear. This enables you to have a conversation without the need to remove your headphones and without the need to resort to a model that has no noise filtering systems. Its volume control is located right in the headphone. Even when the battery has gone out, it can still function as a headset.

Excellent audio presentation, rock-solid construction, comfortable ear cups and soft padded headband; these makes Sennheiser pxc-450 noiseguard active headphones one of the leading headphone models in the market today. As a high-end model, it lives up to everyone's expectations in giving you the opportunity to enjoy and experience your favorite tracks like never before.
