Motorola unveiled Thursday its Endeavor HX1 Bluetooth headset, offering the company's CrystalTalk noise cancellation technology with a "stealth mode" for speaking in especially loud environments.
When the Endeavor's stealth mode is activated, noise and wind are filtered out via bone conduction technology, the same used by special military forces around the world, the company says.
The tech is activated via a button (voice instructions are available), and uses an ear sensor to seal off outside noise, rather than relying on an exposed exterior microphone. As the user speaks, the sensor taps vocal vibrations and converts them to speech so the person on the other side of the line hears only voice.
The device also features Multipoint technology to allow connection to more than one device, and touts seven hours of talk time.
The Motorola Endeavor HX1 will be available in several world regions, beginning with Asia in July 2009. Pricing is not yet available.
