Broken y splitter Blackshark v2 x

I have had my blackshark v2 x for almost a year now but yesterday i accidentally cut my cable yesterday so now i can only use the headset on my phone, i have tried repairing the cable by soldering the two cables with copper in them but i did a bad job and it barely works. is there a way i cand get a replacement part? it truly would be a shame to throw out a pair of headphones just because of a replaceable cable.
