Hi folks. I have a good, working walkman (NW-S703F) but have long since lost the headphones...however, the headphone jack socket has a little step in it, a special shape...meaning that a normal 3.5mm jack plug doesn't work. See attached photo...
Does anyone know if I can buy new in-ear headphones with this plug...or an adapter plug for this?
I've looked online and ebay, etc, but can't seem to find the right one?
Thank you
