One of the ever-present problems with a Bluetooth headset is having an intelligible conversation with someone in a noise-intensive area. When you're in the midst of, say, a violent thunderstorm, the noise pollution around you has a nasty tendency to distort or drown out your voice. Motorola looks to have jumped that particular hurdle with the Endeavor HX1, thanks to its true bone conduction technology.

The Endeavor has a one-touch activated stealth mode. Pressing it turns on the bone-conduction technology, which uses an ear sensor to seal off outside noise. The sensor then measures your vocal vibrations and then translates them into clear speech. Motorola promises that, no matter how loud your surroundings are, you will be heard.

The HX1 is launching in China this July, but it should be spreading to the rest of the world over the next few months. We have no information on pricing yet, but you can check out the Endeavor's website for news here.
