1 micro + 1 headphones to ps4+ pc at the same time?

I have a headphone jack and a Micro with USB port. I would like to use the headset and the micro at the same time on the PS4 and on the PC, to be in Teamspeak but also to play ps4. QUESTION: Which mixer or do I need one? If so which cables?

At my PC, I have also connected a stereo, so quasi hi-fi combined with PC. And if the sound chip of your motherboard sounds good and you have a good hi-fi amplifier at hand where you can connect big speakers, studio headphones, etc., you will get a great sound.
