In my experience, I have gone through 11 different headsets to find the perfect one. I have to say that Motorola has the best. When i used Samsungs, SE, Nokia, Jabra, Logitech etc etc, everyone complained about sound quality & static. But the I tried a Motorola. My first Moto was the H300. I really liked it, but it was heavy cuz it requires an AAA battery. Then i tried the HS820. I like that one ALOT! It was VERY comfortable, but I kept forgetting to turn it off. So I exchange that for the HS850. I love the boom mic feature cuz it is also the power switch. I am prolly gonna change it out again for the h700, which is a newer updated look.
