Proper connection for blon bl-03 replacement wire

[Sound N00b]

Looking to buy a tripowin c-8 cable for the blon bl-03 but wondering if I need to get 2 pin 0.78 or qdc. Edit: if both work does one have more compatibility with other iems and does one work better?

I've just read recently that you need 2-pin.

So QDC won't fit?
