bought both the head set and the adapter to send the signal to the iphone. Works great with the ipod, does not work with iphone,what ever steve did ,he did not allow these great bluetooth devices to work with iphone. The only way to use a bluetooth headset is to plug an adapter in to your cradel,which will send the music streaming that way. I have the plantronics ultimate bluetooth head set,which allows what I just described,plus it allows u to answer the phone. sharper image sells it for 199.00
