I have a jawbone 2 also and put the jabra ear gel on it. Use the smallest jawbone black ring thing and then put the jabra over it (which ever size fits your ear) and then you can take the ear hook off. It takes a little adjusting but as longas the white dot touches your face, it works great. I got mine from radio shack. I have used them on several other headsets as well. This is what you are looking for 6 0r 7 bucks at radio shack last time I bought them
