Those appear to be one of those setups that are paired at the factory. What's pairing? Read http://en.wikipedia.org/wiki/Bluetooth

Hello. I have these headphones http://www.newegg.com/Product/Product.aspx?Item=N82E16826104023&Tpk=logitech%2bfreepulse . The receiver that came with it broke. But the headphones still work. I was wondering if I bought a usb bluetooth adapter or dongle will I still be able to use the headphones.
