Iphone audio to computer

I play a lot of games on my computer and while I do that I like to listen to stuff on my iPhone (Yes proprietary bad I know). Anyway I recently got a pair of earbuds and would like to send the audio to my PC and then combine it with my game audio so I can hear both on my earbuds. I do have a spare microphone port but that the iPhone could plug into but I would prefer to do it wireless so I don’t have to get an audio cable.
