Hi All, I'm looking for some advice on how to connect this all up. Essentially what i'm looking to do is have one studio pair of headphones (DT 990 PRO - 250Ohm) and an XLR mic (Shure SM7B) that I can use for my PC gaming/discord and my PS4 PRO - and be able to chat in party chats and discord as and when needed. Has anyone managed to set this up in a similar way? Thanks in advance for any guidance or advice.
