i have read all these reviews and narrowed my search down to these two. i found them both under 40 dollars. my boss has a plantronics 320 and likes it, but i have heard so many good reviews of the scala that i am mighty tempted to try it. i had the Moto HS820 but it flopped around on my ear too much and i got a lot of echo.

a couple of questions.

does the scala have the little protrusion like the plantronics (i can't tell from the pictures)? it seems like that would allow you to hear better. would it be worth waiting and moving up to the scala 700 instead?
