I don't think it is necessary to use flux on the wick but I don't think it would hurt anything. I suggested the NTC wick only because it is the widest strip for most of my needs but I believe they make them in wider sizes which may help if your current wick is not sufficient.Quite an impressive headphone can collection with a wide sound signature as well. Looking forward to see this project progress.
