Anyway I can listen to pc and PS4 at the same time?

I know headsets like Astros come with a MixAmp that allow that but I only have a headset the connects using a 3.5mm jack any ways I can listen to both with that so I can talk to PC friends while playing PS4?? I saw an older post saying it's possible with a auxiliary cable connecting from your controller to your pc then changing some settings but that was for headsets that plug in via USB will it still work if I only have a headset that uses a 3.5mm jack
