I have a pair of bluetooth headphones that I would like to use to listen to non bluetooth sources. Like many bluetooth headphones they sell a 3.5mm jack bluetooth transmitter in the $50 range. I don't want to spend $50. Is there an app that would allow me to plug my iphone into a 3.5mm jack audio output and have the iphone transmit the audio to my headset? Audio would be input to the iPhone and the iPhone would send it to my bluetooth headset. Could this app be created?
