You might try ebay for a set of bose. I bought one from there and used it under fairly adverse conditions for about six months...on one set of batteries. The earseals finally wore through where they meet my jaws. I mentioned it to the bose folks at sun-n-fn when I visited, and they handed me a free replacement pair on the spot. I paid about half what I would have for a new headset, and was quite satisfied with them.
I've been impressed with the comfort of the lightspeed headsets, too. Good sound, good headsets, and much less than bose.
