Currently I am playing my PS4 with the stock headset and my friends are getting terrible feedback through the mic. So, I have decided that tax return season means time to invest in a nice audio setup for the upcoming games of 2015. I am sold on the Sennheiser G4ME Zero, One, or PC363D. With any of these headsets I am going to need an amp for power. From everything I have read, the Astro MixAmp Pro seems like my best bet. I was wondering if anyone has used one of these setups and has any experience with the ability for full 5.1 or 7.1 stereo sound. Any help would be greatly be appreciated.
