Headphones

I have four friends and we want to bring our own headphones (assume aux jack input) to a vinyl listening night. So basically the record player audio output (mine is RCA out) goes into some kind of hub/splitter and then four aux cables come out and go into each of our headphones. Ideally each output can be independently volume controlled. Bonus points if the device can also accept four microphone inputs so we can speak to each other while listening without taking our headphones off.
