The last Bluetooth headset I used was a Motorola something-or-the-other, and frankly I was underwhelmed. A few years later, I tried thePlantronics Voyager 510 Bluetooth Headset [Retail Packaging], and it was amazing. For the most part, people can't tell that I'm on a Bluetooth headset!The Pros: Great audio quality! Good battery life.The cons: I only wish it had a better earpiece... on that really goes INTO my ears, like mySony MDR-XB20EX 9mm High Sensitivity Driver Extra Bass EX Earbuds. The volume and mute buttons are kinda small and hard to reach/press.Those are just small details though. Overall I am impressed.
