I use the 4i4's multiple inputs and outputs to mix between several sources (PC and monitors) to multiple outputs (speakers, headphones, Bluetooth hub for wireless listening). I don't need both of the front input jacks, but I do use one of them to plug in my bass since I don't have a proper amp at the moment.

It's pretty cool!
