Sticking with the plantronics I have not had any complaints about the cs50 and when the cs 70 came out everyone seems to like that one. The 70 they like since it's not too big and the mic tube is not terribly noticable. People ask about them and I tell them I'll let them try for a month if they don't like it I'll take it back and I haven't had one come back yet. We've had good luck with these so we stick with them.
