Thanks for the replies.
Price was really good from a seller with good feedback and a long membership, though far from a power seller. The box and all seems legit.
I then googled some reviews (after hearing static complaints) and saw a few bad user reviews on cnet (
here,
here,
here) that seemed to 'echo' my results. So YMMV with this unit.
But one review (was 1 yr old) mentioned a sound problem that Jabra was aware of and fixing for a Treo (IIRC). That made me wonder about a FW upgrade. Looking at the box, it appears, perfect but aged. It looks as though it was never used but maybe purchase a year ago, again making me think it might have an older FW.
