So Last Years

To be fair, I could have suggested the Jawbone 1 instead of the slightly improved Jawbone 2, but the prices between the two are so similar that I've picked the newer model from 2008.  Apparently these devices use noise-cancelling techniques developed for the US military; I'm sure that will come in handy when out in the streets of the UK.

This product has also been rated #1 of the top 10 bluetooth headsets.  The newer version I'm sure is just as good, but you can't go wrong with this model at these prices...
