So after using the HyperX Cloud 2 for like 7 months I cannot hear anything from the right ear cup. This happened when I was playing CS:GO. I played several times with the cable going up in the headband, that’s why the cable broke. (Check image) (It’s actually the other cable going up in the headband that broke)

I tried to wire them back and plug it in. It didn’t work because the green wire has a special coating ? (Check Image) (Not the broken wire)

(The broken wire)

Now only the mic and the left ear cup is working, what can I do to fix the wire problem ? I tried to wire them back together but it didn’t work because of the special coating i’m guessing ?

You need to strip the coating. I suggest using a lighter to melt it off. I found that works the best. After its stripped, you need to resolder the cables together, which i assume you know how to do.
