How to set up MMX 300?

[keens]

Hi, I just received my MMX 300's from the mail and have a Astro Mix Amp, however I have no real idea how to set these headphones up for my PS4. Do I need an adapter or something? There is a large jack with green circles and a smaller one with pink circles. Any advice is appreciated.

FWIR on the Mixamp, the headphone output is actually 4-conductor, including the mic input, so you'll need a Y-cable for the MMX 300's TRS plugs to be integrated into a single TRRS plug. That should have been included with the Mixamp itself, but you can buy them separately if necessary.
 
However, I don't actually own a Mixamp myself. You're probably better off asking on Mad Lust Envy's guide thread.
