I bought this exact model of Bluetooth headset a couple of years ago, and it was excellent. When it died on me, I ordered another one, but to my great disappointment, Plantronics changed the design of the microphone. The result is that your voice is muffled to the point where people have trouble understanding what you're saying, especially if you're driving a car, since the noise reduction has suffered as well. Plantronics effectively broke this device when they changed the design.I can no longer recommend this headset.UPDATE:Since writing the above, I have come into possession of another, identical headset, which actually works well. After examining other reviews, it seems that the problem is rather a number of 'lemons' floating around in the supply chain, which are not extracted from the batch offered to consumers in a timely manner. Be aware of this, and be prepared to return your purchase as defective if you are not satisfied with its performance.
