There's been a ton of Bluetooth headset that feature new technologies to help cancel out background interference. Motorola's latest incarnation into the noise-canceling world is their HX1 Endeavor Bluetooth headset which is their first to utilize bone conducting technology. Something similar has been around that Pantech created a while ago, but the improvements on this one senses sound vibrations in your jaw while you speak – aiding in the cancellation of background noise. Users can choose to have the “stealth mode” option enabled with a press of a button. U.S. consumers will have to wait because it will launch initially in Asia this July. It looks pretty and we're hoping that all the hardware packed in the device will provide a pleasant experience; with of course decent battery time.
