I repaired my daughter's earphones a few days ago, the wire had broken where it leaves the plug. These are Marshall Minor (I think) look like this except the plug is slightly different. It's a T-R-R-S plug
So I heated up the metal plug body (just a fancy exterior for a slim moulded plug) until I could pull it off, removed the plastic moulding from the connectors. I think my mistake was to remove the bits of left over wire from the plug, all the extra heating melted the plastic pretty quickly causing a short between tip and end ring. Resolved by removing the tip. Couldn't see anything causing the short, was ok when I put it back in. Cleaned up the wire, soldered on at right angles to the plug and kind of curled it round to fit in the body. 2 layers of heatshrink, fitted in the metal body with hot glue, checked ok with the multimeter, clicks heard when testing. Gave back to daughter.
When tried with Sony mobile phones, the phones said it was an unsupported type of earphone. Tried it on a tablet. Worked, but now the music sounds kind of bubbly or warbly, or underwater as Mrs described it. Even my indiscriminate hearing can tell it's wrong.
So any suggestions what could be causing this? Should I replace the plug altogether, or is there likely to be some other fault somewhere up the wire?
