fix it yourself... easy thing
you can use the old plug,but it just adds extra work by ripping all the plastic coverings away to repair it

buy a new plug
good one will cost a lot
low quality ones just cost 50 cent

if you just want it to make sound then choose the crap ones
but if you want quality so... quality plugs lo...

since it's broken,can rip it a bit more and show us?
cuz the first step is to expose the wire

there'll be 2 colored wire(normally red and blue) and one ordinary brown wire comb around it

2 good one varies from rm50 to rm800(that's for hardcore modders)
you can get good ones from Jaben Malaysia at Subang Jaya SS15

3 you'll need soldering gun and soldering tin
a pair of handy clips helps too(or a friend to help you hold them)
heatshrink helps cover your messy work and protects them from shorting out
