Does anybody know of an app that allows you to use your iPhone as a sort of "wireless headphone"? I want to be able to set my iPad down on the counter, with a video playing on it, while using headphones attached to my iPhone to listen to the audio... through Bluetooth or Personal Hotspot. Another possibiity would be to just "Airplay" the video from the iPhone to the iPad, while leaving the audio playing on the iPhone? The reason I just can't hook up the headphones directly to the iPad is because I'm going to be moving around quite a bit so the iPhone in my pocket for audio would be the best bet. Any ideas?
