If you decide to use mini Pro with cables, then the cables will need to be CS44a for Phonak/Unitron and not standard CS44 cables. Also since we can’t find much documentation on your hearing aids, try looking for cable connection instructions inside the fitting software. Sometimes you need other connectors in addition to the cable.
Look at your hearing aids with magnification or a macro camera/cellphone in the sunlight. Does it have a tiny 4-pin male connection for a cable?
