Yes, the Plantronics 510 seems to work very well with the 1140E. I had a Jabra 5020, but it was very spotty with the 1140E. Like sometimes it would work, and sometimes not. If you get a headset like the PLT 510 with multipoint, you can bounce pretty seamlessly between a cell/BB and the 1140E. To me, so far, this is the best thing about the 1140E, the Bluetooth capability.
