Using a 25% larger wideband speaker and military-grade NoiseAssassin 3.0 technology, users should be able to block out the noise anywhere from a sidewalk to a noisy restaurant.
The motion control aspect makes things a bit trickier. For now, it seems users can shake the ERA to pair with other Bluetooth-enabled devices and tap it to answer/end phone calls. Other unspecified tricks are supposed to be on the way.
Outfitted in four dramatic designs (Shadowbox, Smokescreen, Midnight and Silver Lining), the Jawbone ERA Bluetooth headsets are available online now for $129 a pop. They will also be on the shelves at Apple Stores, AT&T and Best Buy locations by Sunday, January 23.
