Any way to repair this?

[BreadInCaptivity]

Not sure if this is the correct forum but as you can see in the uploaded pictures, my current headphone's(The Superlux HD681 EVO) cable is broken. The internal audio cable is intact but the outer shell is broken. Thought I could patch it up by using heat shrink tubes but then realized it's too close to the base( whatever you call it). Is there any other way to fix it? Maybe some kind of putty?

 

These are the best quality pictures I could get. Sorry about the quality.

It's unlikely to have an actual effect on audio quality (unless its a somewhat low quality cable, and there is some kind of electrical inference in your room). You could just use electrical tape, though I would suggest, opening up the headphones and unplugging the cable from there (assuming its not soldered and your skills allow for that). Other than that, if they are still within warranty you could try an RMA, as long as you have been using them normally and not completely abusing them. I would try the RMA first, because as soon as you open the headphones, your warranty will be voided. You could also get a new headset but I suppose that's a last resort for you, as those aren't the most high-end headphones.

Open it up, push the wire in, solder anything electrical that came undone, hot glue the rest.
