San Francisco-based Jawbone has unveiled the world's first motion-controlled Bluetooth headset - a tiny computer on the ear - taking wearable devices to an entirely new level.

The company's Jawbone ERA device boasts of a built-in accelerometer, MotionX technology, a multi-processor architecture, HD Audio, and richer apps like Caller ID by Name. The headset is completely integrated with the online MyTALK platform. Jawbone ERA weighs 10.2 grams, slightly heavier than the company's ICON model launched last year.

According to the company, Jawbone ERA detects your natural movements when you interact with it. Users can simply “ShakeShake” the headset into pairing mode, and “TapTap” it to answer or end a phone call.

We’re taking wearable devices to an entirely new level. On top of the HD audio, the integrated sensors and intelligence enable magical new ways to interact with the device and apps through natural, intuitive motion control, changing forever the way we use headsets, says chief executive Hosain Rahman.

The company says ERA boasts a 25 percent larger wideband speaker that brings Hi-Definition audio as you talk on the phone, listen to music, watch movies and play games.

Jawbone ERA is available in Shadowbox, Smokescreen, Midnight and Silver Lining designs and is available on Jawbone.com for $129, and at Apple Stores, AT&T and Best Buy stores on January 23.

The next era of personal technology is about products that adapt to the way we live, says Rahman. The best technology will reliably and seamlessly take the friction out of any experience.
