The logitech G433

I am thinking about getting the Logitech G433 headset for so many reasons including the 7.1 surround sound system.... I just have one question though..... Will I have a 7.1 or a 5.1 surround sound on my ps4 using the headset.... And if it is gonna be a 5.1 then how can I make it 7.1. Thx in advance.
