I'm about to get an Icon for my 9700 in the next week or so. My experience with my other two Jawbones has been flawless though. I will be very surprised if I experience the same trouble you have. I would call Jawbone and get them to send you a replacement if it continues. Their customer service is very good and I received two replacements for my JB2 when asked.
There is some talk about quality control problems in their production, but they do make good on making you a happy camper.
