Plantronics Voyager 510 Bluetooth Headset

Pros: it is confortable

Cons: none really

Summary: I had a motorola HS850 and a H500, both were good until I got the Voyager.
The main issue I had with motorola was that they will flop against my ear everytime turned my head. With the Voyager, it always remained in place, I thought it was going to feel heavy but it did not.
The only thing that bothered me was that it was hard to turn on the first time, after that it remained on all the time.
