If the crackling occurs only when opening windows or another program, the crackling is not due to the headphones but to a lack of CPU resources in your computer settings.
If you are in Windows 7,
  1. click the Start button 4f6cbd09-148c-4dd8-b1f2-48f232a2fd33_818.jpg, and then click Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.

First, have you checked the headphones on multiple devices, or only one device? If you have only been trying it one one device, it could be that the jack in that device is bad.
If they don't work with any devices, it probably means that the connector is bad on the headphones, or that the wires are faulty. Do they connect with the tiny 3mm (standard) jack, or with the larger TRS (looks like a guitar cable) jack?
It is also possible that one of the speakers may have been blown out. Have you recently been listening to anything very loudly on them, especially with an external amplifier?
In any case, I would recommend taking them in person to an audio expert.

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.

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!

It sounds like the wires around the jack have become frayed on the inside. If you were to open up the rubber casing around the wires, it would look exactly like that. This is normally caused by improperly wrapping the wires and by not being gentle when plugging them in and removing them. It could be caused by other things, such as electrical damage, but that is much more rare. If you have soldering experience and feel comfortable opening up the rubber casing and working on them, it's not too difficult. You would need to remove the bad portion of the wire and replace it. However, it is just as easy and cost-efficient to have them fixed at an audio repair shop. It should cost no more than $20. Hope this helps!

Hi, Ian, If you have soldering experience, you might be able to replace it by yourself. If you remove the portion of the wire that is frayed and replace it with new wiring, it might work. If you feel comfortable doing this, I would say go ahead. However, it might be just as cost-effective to take it to a local audio-repair shop and have them do it. I have had multiple sets rewired myself, and it has cost less than $20 each time. Either way, it should be a relatively easy and cheap fix.

There are two likely causes for this. One is much, much easier to fix than the other.
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.

you need to open it carfully and see if cables or one cable or broken
If the one cable its broken you need to solder it the speaker

The two copper wires on your headphones are independent grounds for each channel. Twist them together and attach them to the ground cable ( black) of the new plug. The colored wires of the headphone correspond to the live wires of each channel, and the plug should have the same colors. Wiring together the grounds will not affect in any way the stereo separation, it is just that each ear needs its own ground. Cheaper headsets just transfer the ground from one ear to the other one through the metal headband.
