Motorola HS850 (3rd one to date) and don't like it!!It is a convenient piece, but sound sux and people always say it's like talking to the teacher from the Charlie Brown cartoons from back in the day...I am switching to the Jabra JX-10 in black...My perrs at work have it and they all love it with no jarbled voice issues at all. Note*** DON'T DROP YOUR MOTOROLA ON ANYTHING LIKE CONCRETE*** I have broken one just by a short drop...It fell completely apart, and the speaker was trashed after that. To my surprise, the guts are from GN Netcom who is big in headset technology, but missed the boat on that one.
