Well, there is Zippo's "Infocom," at http://lab108.x0.com/lab108/sf.html I've used it in images. Maveris has a "Sci-Fi Headset" here in freebies; go to Free Stuff and use the search term "Headset." And of course Turbo-Squid has actual Bluetooth headsets....I saw a Motorola model (in Max format) for $25.
