Nokia today launched the Nokia Bluetooth Stereo Headset BH-905 with active noise cancellation combines two in one - both music and calls - and provides clear sound by eliminating background noise with novel active noise cancellation technology from Wolfson Microelectronics. This multi-microphone feed-forward active noise cancellation technology allows for pure sound without ambient noise and is now introduced for the first time in the Nokia Bluetooth Stereo Headset BH-905. Here is more info on the Nokia BH-905 Bluetooth Stereo Headset with noise cacellation:
"Technically the noise cancellation is solved with a total of 10 microphones: 8 microphones for cancelling noise and 2 microphones for capturing speech in loud surroundings offering advanced noise cancellation for clear sounding phone calls.
The design is simplified to its extreme, ensuring that its functionality is not compromised. Details made of stainless steel ensure a quality and precious look through time and soft ear pads provide comfort. The headset features a dedicated multifunction key for call management, as well as music and volume controls, and a switch for activating the active noise cancellation.
It is compatible with a wide variety of devices. Wirelessly with any device supporting wireless Bluetooth technology, and with wired connection with all Nokia devices with 3.5 mm Nokia AV and 2.5 mm Nokia AV, music players, PCs and other devices with standard 3.5mm jack, home stereos with standard 6.3 mm jack as well as airplane players.
