Just curious if there is a way to do this without a computer- can you use bluetooth headsets with the CODE 50 as a monitor when you play? In other words, I tried to use my headphones (wireless) to connect to my phone while the app is running, and I can't get any feed from the amp into the buds. Just wondering if there is a way to hear the amp wirelessly with the buds while also simultaneously having the amp speaker still audible.
