What would be the easiest way for me and my wife to use headphones and hear each other play along to music? I use an old LG V20 as the source to play the music and its plugged into my edrums and plays out of the edrum amp. She has a Fender Rumble 100 with XLR out and my Roland amp has mono or stereo XLR out. we both have Sennheiser HD280 Pro headphones. The roland module has MIDI also. I also have a Zoom H6 recorder but not wanting to record both of us right now. I was looking at something like this M-Audio AIR 192X14 USB Audio Interface. I want to be able to mic my acoustic kit and use it for that some day also along with the Zoom H6. Wanting to keep it cheap and compact.
