So I have Razer Tiamat 7.1 headphones which work incredible on my PC with Xonar DX. I also have Xonar U7 which I want to use with my PS4. However I am not sure how to connect it to the PS4 because it has Optical and USB cable... and I am not sure how to connect the tiamat to the sound card. I also have Sennheiser G4ME ZERO which has 2 x 3.5mm jacks (one is for mic). They are 150ohm so I should obviously connect em to the front panel of the Xonar U7 (where the amplifier is)? And can this amplifier support 150 ohm or should I buy separate amplifier? And if I have to buy separate amplifier, which one under 100$?

P.S. 1. For different games I like to play with different headphones.
2. I am from Bulgaria so I cant find most of the amplifiers here.
