link - that is the one i use. not only is it a bluetooth headset, but it doubles as my bluetooth headphones too, so it works perfectly with my iphone when im listening to music via A2DP, transfers to my calls whenever they come in, and goes back to the ipod after im done.
i love behind the neck styled headphones...they've always been the most comfortable for me, and now since its wireless, its even better.
edit: spelling, and in response to OPs question, they were never in style for me personally...they were just there for functionality.
