The unit I have is too old to take the TENS wires that plug right into the unit. The initial wires coming out of the unit are hardwired into the unit and there is a snap connector on the end and the alligator clips are snapped on to this. I ordered the snap to pin converters after reading through this thread but what I am worried about is it looks like the converters are either only male or only female snap connections while the snap connector I have is one male and one female.

Also where can you get the elastic headbands? I have tried the ace bandage and it will due but I believe the elastic headbands would be easier. I tried emailing the generic email on the Soterix site but I did not get any response.
