Jawbone is a high-tech Bluetooth headset designed to be used with mobile phones like iPhone. What makes Jawbone so high-tech? According to the manufacturer it's the only "adaptive" headset on the market today. It uses military-grade audio technology that adjusts and optimizes incoming and outgoing sound quality based upon the current audio situation.

Again, according to the manufacturer, there are four key features that differentiate Jawbone from other headsets:

• A voice activity sensor
• Two separate microphones
• Proprietary noise shielding technology for noise subtraction
• Adapts at 380 times per second
