Hi Travelin
I have seen a few coiled cables from China like that but they have all been 3 conductor NOT 2 conductor + a shield. Not sure what the application is. Do you need a proper shield? I'd guess you would. Not sure if Ted or any of the other cable makers can get raw coiled shielded cable appropriate for 3.5mm.
Good luck! I'm interested to see what you can find.
