head set pxc 450

The company sennheiser presented the new head sets with the function of noise suppression PXC 450, dedicated for those who listen to music in the road. Head sets have the closed construction of circumaural - the membrane of large diameter, embouchures fit closely to the head and completely are shut ears.

As producer reports, the active system of noise suppression noiseGard was originally developed for air pilot, for which was necessary the high level of protection from the ambient noise with a good acoustic fidelity. The principle of operation noiseGard is the following: miniature microphones measure the frequency and the level of noise around the user, the inverted acoustic wave and then is generated (with the phase of 180 degrees). Noise and its phase-inverted copy are superimposed and practically liquidate each other. In PXC 450 is used the second generation of this system - NoiseGard 2.0, with those improved by the circuit design compensator and microphones. Sennheiser promises, that the head sets will sift to 90% of noise (23 dB).

Is sufficiently interesting the function Of talkThrough, which makes possible to associate with the people located near, without removing head sets. With the activation Of talkThrough external microphones are switched into the regime hearing of external sounds. In this case the sound, which emerges beyond the framework of frequency band, which corresponds to human voice, is filtered, and user hears against the background music purified and improved speech of collocutor.

Ergonomic quality PXC 450 is improved also because of the buttons for the adjustment of loudness level, done in one of the head sets, and also the detached cable. For the power noiseGard use one small battery AAA, without which PXC 450 will work in the usual regime.

New product will appear in stores during March on price of 500 dollars.
