Hi
I’m sorry but I don’t know how to take skullcandy headphones apart how ever I have tonnes of experience with beats
So long story short from whet I have seen most headphones come apart the same way
So chances are the ear pads will need to be pryed off witch should reveal some screws and once you have removed them a plastic midframe should come out after the the speaker/driver attached with two cables attached to it
By the way I would check the disfunctional sides cables where they are soldered as is it very common for the solder to break and let go of the cable Witch causes them not to work
If you need any more help please do not hesitate to ask
Sorry again as this information is to be taken with a grain of salt but I should be on the right tracks
Thanks:)
