Fixing damaged headphone cables?Hey,
I have a pair of headphones that, for some reason, stopped working. When i twist and bend the cable in a certain place though, the sound comes back, sometimes either in one ear or both. So I guess I'm pretty certain a few wires inside are broken or something in that particular spot. Normally in this situation I would throw the headphones out but this is a pair of active noise cancellers, so I really don't want to.
Would it be safe to slice open the insulation around the spot where I think its broken to find the broken/damaged wires? And if I find them, is it feasible/possible to fix them DIY style?
Thanks in advance!

I agree about dexterity Alex! Used to be able to mend them cutting out the faulty section. Over the past 10 years or so wires/cables have got thinner and thinner and very tricky especially when trying to strip them (so sensitive!) & link them together and solder! I thought somebody might have a technique. Anyway I'm going to have a go at my Sennheisers. At their price I'm reluctant to just throw them away. Have to say Sennheisers in the 70's were much more robust and my HD414'S (Hugely popular then) suffered every test, treading on them, pulling the cables repatedly & quite hard at times (accidentally!) and they never failed!

Hi Chris,
I had the same problem. The headphone on either side is supplied with two wires which are both insulated and usually are of different colors (reddish and yellowish). The two wires are insulated from each other to prevent a short circuit.
If you cut the wire and then try to twist or solder the wires together, not realizing there are two wires, you will create a short circuit and you won't get sound. Also, since the two wires are well insulated, re-attaching the ends is not an easy matter. What you would have to do is try and strip the ends of both wires free from the insulating material, and then solder the pieces back together. REMEMBER: DO NOT solder the two main ends as if they are ONE wire. Since the current on both the Right and Left earbuds requires a complete circuit, each side (Left and Right) has two separate, insulated wires, which must each be soldered independently with like color wire.
If the point you suspect is broken is near the earbud, you could remove the remaining piece that attached to the earbud and solder the remaining ends, thus circumventing the old wire. Again, you'd have to strip the ends of each colored wire free of insulation, which is no small task since the wires are very tiny and you can easily cut them.
Given that this task requires a lot of dexterity and precision, I suggest simply buying a new headphone set.
