Query: Plantronics Voyager 510 Bluetooth

Before purchasing, I researched Bluetooth headsets pretty thoroughly online and settled on the Platronics Voyager 510. After 3 weeks of using (I only use it in the car), it seems to have been a good choice so far - the price was one of the most reasonable and the sound quality is good. It also holds a charge for several days at a time, however, I do turn it off when I'm not in the car. My only criticism is that since I don't leave it on my ear all the time while I'm driving, it's sometimes a little tricky getting it on my ear when the phone is ringing and I'm trying to drive. The accessories for it seem unnecessary - I wouldn't waste the money on them.
