There are a couple of oddities about the Jawbone though, mostly surrounding its control system. Although there are two buttons, neither of them are visible - they are positioned underneath the fascia, and activated by pressing in their general vicinity. That's all fine, until you come to adjust the volume. Unlike most Bluetooth headsets that have volume up/down controls, the Jawbone will cycle through its volume settings in a wrap around manner, so if you want to turn it down a notch, you can't do so without turning the volume up to maximum first and wrapping back to the start.
But even taking those foibles into account, this is still a first rate hands free solution for anyone that doesn't have built-in Bluetooth support in their car. The only downside is that the Jawbone is pretty expensive compared to other Bluetooth headsets on the market. The best price I could find for this new Jawbone is around £75, which is a pretty hefty investment for a Bluetooth headset, even compared to Apple's overpriced iPhone headset. That said, you are getting some unique design and technology features with the Jawbone, and it does work better than any other headset I've tried.
There's no denying that the Noise Assassin technology inside the Jawbone works supremely well, and knocks most other Bluetooth headsets into a cocked hat. The Jawbone also looks superb and is incredibly comfortable to wear, even for extended periods. All that functionality, style and comfort does come at a high price, but as always, if you want the best, you're going to have to pay for it.
