Hi, I just built my new gaming pc and I want to use the headphones i bought for my ps4 with it but i only have 1 3.5mm plug in, and i need one in the mic an headphone jack to use the built in mic. I am using the turtle beach px22's but i don't have the in-line amp or anything like that, just the headphones with a single cord running out of them. how do i use the built in mic and headphone at the same time when i can only plug them into either the heaphone jack or the microphone jack
