Reply to Sound cutting off on Sennheiser HD 25's

Pretty frequently, I have audio cut off on my left headphone of my HD 25s. After searching the internet, I found a solution, although a bit tricky for someone who sucks at fixing shit. I heard replacing the cable is another, more expensive fix. I have been wanting to replace the cable with something custom like the ones MDCDesign makes. Has anyone had this problem, and if so, did a new cable correct it?

Here's a link to the fix if anyone needs it: http://www.instructables.com/id/Senn...se-and-Repair/
