About a month ago, I purchased all 3 headsets: The z9i, original jawbone, and Plantronics 925. I then had my wife run some tests with me. I called her using each of the 3 headsets, talked a bit so that she could get a base quality rating, then turned on a radio right next to me. The jawbone won hands down. She said that she could clearly hear the radio noise with the other 2. We then repeated the test using the garbage disposal instead of the radio. Same results. YMMV, but the Jawbone was the clear winner according to my most critical listener.
