It is what I found by searching long range bluetooth adapter, http://www.kanda.com/products/Kanda/PARANI-UD100.html?source=froogle, it claims 300 meters and up to 1000 with the antena. Will I really get this range? If I do will any devices even support that? I am concerned because I can't find this in many places online and especially can't find anything else that claims that kind of range that is this small and only $50 okay time for part two *takes a deep breath* so I was looking at using bluetooth adapters for my school (small gym) to use bluetooth headsets for mics, however I am fairly certain that only one of most things will work through bluetooth at a time AND we would have to make them all work with some type of play through feature. I know other people have done this type of thing but HOW?
