Does it matter that I touched both color wires of each one to the terminals?
This may be my problem. When I cut one strand of wire, there are already 2 types of wire, copper and red/green. Maybe I should use THOSE 2 instead of 2 separate strands of 2?
Let me see if I understand you correctly: you have two lengths of headphone wire, both of them with two wires in it (one not-insulated plain copper, and one insulated (with a color)), and you have connected both wires of one length to + on the battery and + on the Ben, and both wires of the other length to - on the battery and - on the Ben? And neither length is connected to the other?
If so, this should not be a problem in itself, as long as there is an electrical connection - but you should only really need one wire for each of + and -, so you could instead use just one length and e.g. connect the uninsulated wire to - on both, and the insulated one (after stripping some of its insulation) to + on both.
Or if you prefer to use two lengths, you could connect just one wire from each (e.g. the uninsulated copper wire).
In either case you need to be careful so that + and - don't touch each other anywhere - there must be some isolation between the two.
One thing you can try is, after connecting the wires to the battery, measure the other ends of the wires to see if there's a good voltage there. If not, there either isn't a good connection between the wires and the battery, or (at least one of) the wires is broken.
To figure out which wire has the problem, you can measure between the other end of the + wire and the - connector on the battery (or vice versa), if that gives a good voltage then that wire should be OK.
Once you've connected the wires to the Ben, you can measure on its contacts to see if there's a good voltage there - if there is, you should be good to go (as long as you haven't gotten + and - reversed).
