So many Bluetooth headsets look foolish — particularly when they are not actually being used and instead are worn as fashion statements.

Still, the easy connectivity and the wireless, hands-free convenience are worth looking like a cyborg wannabe, particularly whether the earpiece works as well as the new Jawbone from Aliph.

The newest incarnation of the company’s flagship headset went on sale recently through AT&T Wireless, and it’s compatible with the most common versions of Bluetooth mobile phones.

Just for the record, Bluetooth is a short-ranged wireless technology used to connect one device to another, such as a phone to a headset or a keyboard to a computer.

The Jawbone 2 doesn’t look like your typical headset. Unlike many other Bluetooth earpieces out there, all of the Jawbone’s buttons are on the inside. You control the device by pressing down on it in specific places.

The USB-based charger even comes with a wall outlet adapter, which is a rarity among consumer electronics makers that like to sell them as a separate accessory.

The Jawbone’s battery runs for about four hours of talk day, depending on the phone, and about eight hours of standby.

But it is inside that tiny $130 device where the specifications become truly impressive.

The creators of the Jawbone 2 say it can accurately separate speech from ambient noise by using a proprietary technology sexily named NoiseAssassin. The system uses a “voice activation sensor”…
