I tried replacing the cable for my HD600s because I was having problems with sketchy/broken up sound as if there was a bad connection between the cable and headphones.
However, it hasn't done anything, so I assume it's to do with the socket itself (like the metal of the socket has been pushed back or something). Is there anything I can do about that, or do I need to just replace them with some new ones now?
I've discovered the solution to the problem, I think. What has probably
happened is that while wearing the head phone you have probably caught
the cable any number of times on door knobs, under your heal, or
perhaps around the feet of a passing dog. The cable is very long and
very strong — it's Kevlar reinforced.
All this jostling has
tended to bend the pins and probably the sockets they plug into. Using
a delicate pair of jewelers pliers, preferably smooth-jawed, gently
bend the pins outward (maybe even inward) so that they once again make
a firm contact in their sockets. It's worked for me pretty well so far.
fact that some people get no improvement from cable replacement
suggests that the problem is with the internal cable sockets. The
solution is still the same. I notice after doing a tweek that the plugs
feel tight again.

1) You are turning up the volume too much. Headphones, especially non-top of the line headphones, are not meant to be listened to at very loud levels. In this case, the crackling you are hearing is the speaker trying to reproduce a bass sound that is "clipping", or exceeding the maximum output level for that system. Remember - headphone speakers are very small; they have a harder time producing low sounds accurately. The solution is to just turn them down a little. 2) Assuming problem 1 is not the problem, the other likely issue is that they came with some sort of mechanical defect built in. If you are not playing them loudly, but you are still getting a crackle, especially if it is only on one speaker, they probably are broken. It is probably the jack itself, or the wiring leading up to the earpieces. Either way, it is not a terribly hard fix if you have some electrical know-how, but if you don't, there are plenty of people who can rewire them for much cheaper than it would be to buy a new set. However, if this has been happening since you got them, I would call the manufacturer first and see if they will replace them. Sennheiser tends to pride themselves in the quality of their equipment, so I would not be surprised if they sent you a replacement set. Hope this helps!
there will be 2 wires in different colors inside the cable,
these wires are enamel coated and sennheiser has best quality coating over the wires, so soldering this could be a bit messy - this is the procedure to do so
first take out these wire leads out for about a centimeter from both the ends, try to loosen the leads and yo will find small clustered strands of fiber wound between the leads try to remove those fibers (only the visible ones) completely from both the ends of the exposed leads. take a blade and try to wipe out the enamel coatings from the wires (make sure that the 2 leads does not touch each other after removing the enamel) now connect (solder) both the ends of the wire with their respective leads (eg. red with red or green with green as applicable) now you should be good to go
Please understand this is a delicate job and require atmost attention use cello tapes wherever applicable and tie knots at correct places to avoid further damages
the problem is the cable from one driver to the other suffers from fatigue due to the bending of the plastic frame as the headphone fits to your head, causing copper cables to disintegrate.
the solution is to take apart the headphones (mini and regular Phillips screwdriver ONLY required) and solder a new cable in. in my case i used a standard coaxial cable for replacement.
once you have split the end of the senheiser cable output from cup 1 into its two parts you need to attach it to the equivalent connections on cup 2 (which u also need to split, i suggest using a modeling knife)
the red wire is insulated with ceramic coating much the same way as an electromagnet winding, the other is standard copper. you must attach copper to copper red to red with YOUR OWN cable.
the most difficult part is removing the ceramic insulation coating on the red wire, which i removed with a blast from a cigarette lighter. simple.
problem is your cable probably will not fit in the slot designed for the previous cable so i drilled a small hole in the BACK of the cup (silver colored horse shoe shape) and ran the cable outside the plastic case. not pretty but it saved me £40 for 2 hours work, which is not bad.
i am a trained mechanical and electrical engineer so u can trust.
Go inside and test the speaker with a small low power battery, connect it quickly (just a quick touch) to the terminals of the speaker, it should pop! If it doesn't it's gone.
If the Sennheiser don't have replacements, then it's bin time!
