Chosen Solution

i have two separate issues currently with my Sony WH1000-XM3s. I’ll talk about the one the title mentions first.1. A couple of days ago my right earcup speaker started making this god awful sparkling/crackling noise that made the headphones practically unusable. I opened up the earcup to see if there was moisture damage or anything. However I couldn’t find anything except a little bit of corrosion on some of the screws, which I don’t think should do anything. The odd thing is that the issue got fixed and the only thing I actually did was unplug/replug the gesture control cable. This COULD be the issue because the gesture control “self activated” a couple of times during the day the problem occured. However this doesn’t seem like a permanent solution to me. So what I’m wondering is, does this seem like a sensible cause, or is there any way I can diagnose further? Does anyone have any tips on a “permanent” fix?2. The extension sliders are both broken, and have been for a couple of years (I’m lazy so I just taped them). I’m now trying to find a way to permanently repair them but can’t seem to find any reliable spare parts that are not ludicrously expensive (Sony’s seem to be like 50€ PER SLIDER. Does anyone have any tips on how to find such replacement parts? Example of cracked extender i found online:

This is exactly what happened on both sides of my headphones, it seems to be quite a common issue.Thanks a lot for answers! I’m a student so don’t really wanna drop 300€ on new ones if these ones can be repaired :). EDIT: Issue has been solved so I figured I’d post what fixed it for me. The crackling was due to corrosion on the connector to the gesture control touch board. Probably caused some sort of short that then messed with the speakers. So get some Isopropyl alcohol and rub it off :)I also fixed the sliders with the help of a friend that does 3D printing. There apparently are existing 3D models of the parts, so they can easily be printed and replaced. There are guides for this online that explains it better than I ever could. —————————————————————————————-

@luddoro you do want to go ahead and disassemble your headphone right to the speakers (drivers) and check the logic board for corrosion on the components as well as check the wires for corrosion and fraying. I suggest that you also replace the battery since that can cause weird crackling as well as other issues. As for the sliders, we really would need to see what the broken ones look like. There might be a more permanent fix for it or your may have to purchase replacements. You could always check places like ebay.com for a pair from a broken headset or try to find somebody to 3D print those for you. It’s a fairly expensive headphone so parts will be expensive as well.
