The Jawbone line of Bluetooth headsets have long been known both for their high end features as well as high end prices. The new Jawbone ERA continues both trends by adding a few new features including an accelerometer as well as Motion-X technology and multi-processor architecture.
The ERA makes use of the accelerometer with the "TapTap" function, which allows you to tap the headset twice to answer or end a call, as well as the "ShakeShake" function that lets you shake the headset four times for automatic pairing mode. This pretty much does away with any need for buttons on the Jawbone ERA, which is fine by me as long as it's built to last. Updates to features like Noise Assassin technology along with "HD Audio" for improved call volume and clarity are also included. All of this for a hefty $129.99 price tag.
