hi i dont have same camera as your but ...
in my opinion when u got HeadPhones Out Put u can use any cable u like to use.. but it must be just regular small jack ( depend of input in some times its another type of plug )...
ofcourse cables are very very importand

,, biger better

,,
i just check out that sescom cable and i dont see anything what can make this cable special...
double stereo out put jack ? no problem..u can eazly buy similar lookn cable and it wil lworks... but if u can control some audio setings with sescom cable its another story.. but if this cable is only for put sound out ..u dont need this sescom cable...

,,, u want good cable ? look for same lookn cable but in AudioPhiles shops i guarate you u will take More quality More less noize and Muche more Expensive xD cable.. but sound what u record will be UNCompartable to sound with regular cable..
so.. u can use regular cable (like Sescom ) and u get noize or weird stuff in sound cus cable is low quality.. or u go Pro and u buy AudioPhile Cable..
that Sescom cable like on first looks its nothing special and in my opinion price 5$ will be overpaid for it
