A:
I have a friend that has the PS4 Gold and I have the PX4 and after trying both I would say the Turtle Beach headset provides superior sound quality as it is true surround and the Gold is virtual surround.
On the down side you must have the PX4 hardwired to the controller to use the chat function. That's the only con I can see so for me it was an easy choice real surround or virtual...I choose the Turtle Beach.
