I have two pairs of the OnePlus Bullets V2 which broke in the same way (bent male aux connector), so am trying to solder new connectors onto them, but unlike any headphones I've taken apart before, these have 6 wires, and the colour coding seems arbitrary.

I am assuming the wires are left, right, mic, and then a ground wire for each. Is there any way I can figure out what wire does what, without a multimeter?

Edit: I have already attempted to contact OnePlus support for such information but it seems it's against their policy to supply it, likely to decrease the likelyhood of knock-off products being manufactured.
