Use special microphones to detect what sounds should be negated

Creative isn't about to let much time pass without some new product announcement, so it launched the HN-900 headphones, which can work with iPhones.

One would think that a big and solid headset would be meant to serve users when they are in front of a computer, but this is not the case with the HN-900 noise-canceling headphones.

Though it can do such things well enough, it is unusual in the way that it boasts an in-line microphone and switch that allows for one-click voice communication on an iPhone.

That said, microphones are actually an important part of the new product.

Indeed, there is more than one, quite a few more in fact, not just the microphone that captures one's voice.

Creative actually placed some of them in the ear-cups, where they detect surrounding noises so that they can be electronically negated.

The process eliminates about 85% of all noise that would otherwise bombard the ears of the wearer.

Of course, there are times when people might not want to become so totally lost in their virtual world, so Creative made it possible to turn off the noise-canceling feature.

Not only that, but there is even dual-mode usage, which lets the headphones run the noise-cancellation function on battery power (four AAA alkaline batteries can last for up to 40 hours) or in passive mode.

Moving on, two finely-tuned 40mm Neodymium drivers actually produce the sound.

Also, the frequency response is of 20 Hz to 20 kHz, the sensitivity of 1 kHz of 100 dB/mW and the impedance of 290 ohms.

Other specifications include a cable length of one and a half meters and a product weight of 168 grams.

The Creative HN-900 should be available, or will start shipping soon (by the end of November, 2011) in Asia, for a price equivalent to US $99.99 (75.01 Euro).
