Amazon.com: 2.5mm To 3.5mm Stereo Audio Jack Adapter (2 rings): Cell Phones AccessoriesI have the a40s with the mix amp pro. The game/tv/movie audio is great. only problem is that the mic chat jack on the mix amp is a 2.5mm for the xbox 360. I doubt there's an adapter that will work with the ps4's iPhone type 3.5mm jack. The website says to use the usb cable plugged into the ps4 for the chat audio but i like having the mix amp by my couch and don't have a usb cord long enough. Maybe if the a50 has all the volume control on the headset it won't be a problem. My problem with the a50 is the battery pack isn't removable/replaceable, when it craps out you're fucked.
You mean like a 2.5mm To 3.5mm Stereo Audio Jack Adapter? There's a bunch of different ones of these on Amazon and such.
Edit: Hrm, guess the one I linked says no Mic line. There MUST be one with a mic line somewhere!
