The Motorola Endeavor HX1 is the latest salvo in the Bluetooth noise-reduction arms race, and it takes it to another level -- reading the bone vibrations in your inner ear and digitally converting those vibrations into recognizable speech. That's right, when regular microphones fail, when even noise-reduction won't work, Motorola is actually turning off the microphone entirely and reproducing what you say based on sound waves in your skull. It won't sound as good as a mic, however, but in a crowded place like the floor of CES 2010, rather than a dull, indistinguishable crowd roar, you can actually be heard.

[UPDATE: And the iMore Store folks told me they just got the Motorola Endeavor HX1 in stock, and it's on sale 31% off, if the video entices...]
