Audio adapter for Bose
 

I currently have the previous version of the Bose aviation headset (Bose Aviation X I believe) and was looking to find an audio adapter so that I could listen to music while flying. I know the new A20's have this option but I don't have the money to dish out right now for a new headset and was looking into the option of finding an adapter with an aux chord so I could listen to music on my longer legs. Does anybody have anything they could recommend? I found one or two online but they had poor reviews. I noticed the one Sporty's sells supposedly doesn't cut out the music for ATC. Any input would be appreciated :D
