KSC75/PX100 worth fixing?

I have a pair of ksc75s and PX100s which are both not working properly, I'll say that I'm a complete newbie to anything related to DIY since I haven't even soldered anything together before.

I'm wondering if its worth trying to fix these or throw them out, the ksc75 i think the driver in the photo just needs to be connected to the cable but I don't really know how to do this so it works. The PX100's driver which is disconnected from the frame isn't working, I'm thinking it could also be a cabling issue.

I know Koss have life time warranty on the KSC75's but I don't have a receipt and I'm in Australia so it's probably not worth the shipping costs when I can get a new pair for around $25. The PX100's are a bit more expensive so I'll probably have to throw them out or find a way to fix them :P

If anyone can help me with ideas or what to do me and my ears would definitely be appreciative! Without these I'm currently listening to some sony noise cancelling headphones (mdr-nc6) and prefer the sound of both of these headphones.

Fix them. They are both nice pair of phones and it will kill some time fixing them.

Alright so fixing it is, the next question is how

For the ksc75's I've seen clips of soldering those two split ends together via melting a thin piece of metal with a soldering iron. How do I connect the split ends to the driver so that sound works, I tried pressing each end to where they are supposed to go but no sound came out but it was with my fingers lol.

PX100's have no idea how to fix or even open, I'm just guessing that maybe the cable is loose on the driver lol.

The KSC75s have wire that has an enamel coating around it. You should remove that first and then solder the wires to the appropriate pads. A good way to do that is to burn the enamel of with some hot solder. Do it right and your wires will be tinned and ready for soldering too.

The PX100s should have (very) tiny (I believe philips) screws. Look for them and see if you can open them.

Good luck!

I wrote a little guide to disassembling the PX100s a while back...

Hope that helps!

Disassembling both is easy. Go for it. Just don't use a thick cable or they will break again.
