I have been in search of a new headset now for the last couple of weeks since my Plantronics 640 decided not to work more than three feet away from my 7130. After reading and reading and doing more reading it looks like it comes down to the Plantronics 640 / 645 or the Jabra JX10. I am wondering though if anyone has tried out the SE HBH-IV835 http://www.sonyericsson.com/spg.jsp?...p4_1&pid=10417 ? The featureset looks promising and it's even prices a little less than the other three mentioned. Howard Forums has mixed reviews but no one mentions trying it out with a BB.
