"The only situation where the Jawbone wasn't as impressive was in the plane on the tarmac, with people streaming down the aisle, flight attendants making announcements, and the blower overhead blasting air onto my face. In that case, the Jawbone did cut the noise, but the air from the blower still created a sort of static-like sound that made the call very annoying to the person I had dialed. There was one big problem. On most of my test calls the people on the other end reported an echo effect -- they could hear their own voice echoing back at them. I didn't hear this, but it's obviously a major annoyance. Aliph says this isn't common and speculates that it might be due to the phone or network rather than the Jawbone. But when I removed the Jawbone and just used the phone normally, the echo went away. If this is a common issue with the headset, it will have to be fixed" is it the case that at some point folks will realise you need more than a volume control and a noise cancellation - you need an adaptive and line echo canceller and a shock protection device? much wait and seeing for now?
