HS50 headset jack bitten off by dog

[fi11222]

The title says it all.

 

Now I am trying to repair it.

 

After slicing the cable open, this is what I find:

 

1) 1 bare copper braid which looks like it is the ground.

2) 3 wires: red, blue and transparent

 

I suspect that the red and blue are for the 2 earpieces and the transparent one is for the mic.

 

Can anyone confirm this (or tell me otherwise) ?

 

Thanks
