I originally bought the Plantronics Voyager 520 Bluetooth Headset It worked OK and I would have kept it...until a couple of colleagues started raving about how well the Jawbone Noise Reduction worked. On their recommendation I exchanged the Plantronics Voyager 520 for the Aliph Jawbone. Once the Jawbone is fitted correctly, it works incredibly! You can use the headset in any noisy environment and the person on the other end can hear you perfectly. Whether you're in a noisy bar, or a convertible with the top down, you'll still be having normal telephone calls. The only caveats are that it has to be fitted correctly in order to work. It comes with numerous over ear hooks and rubber inserts to help you find the perfect fit. It might take you 15 mins to try all the options and get it right. And the last minor complaint is that the charger is a tight fit, so you sometimes have to wrestle with it to get it unplugged.Aliph Jawbone Noise Shield Bluetooth Headset- BlackAliph Jawbone Noise Shield Bluetooth Headset- RedAliph Jawbone Bluetooth Headset- Grey [Bulk/Generic Packaging]
