=== ***Precautionary*** ===
Adhesive holds the felt down, so you may need to glue it back on when reassembling your headphones. ***There are no replacement parts for these felt covers.***
***Step 7 requires soldering skills and precision.*** If you’re not experienced with soldering, seek assistance.
=== ***Tools & Materials Needed*** ===
* ***Soldering iron*** (for ribbon cable and jack desoldering/soldering)
* ***Solder wick*** (to remove solder cleanly)
* ***Solder*** & ***soldering flux*** (for secure electrical connections)
* ***Metal spudger*** (for prying apart parts without damage)
* ***Plastic spudger*** (optional, useful for delicate internal work)
* ***Precision tweezers*** (for lifting cables and components)
* ***Wire stripper*** or ***X‑Acto/box cutter knife*** (to prepare cable insulation)
* ***Heat source*** (micro-torch, candle, or match) – to burn/enamel coating from headphone wires
* ***Adhesive*** (e.g., craft or hot glue) to reattach felt covers securely
* ***Replacement audio jack*** (matched to original specs)
* ***Safety glasses*** & ***heat-resistant workspace*** (for personal protection)
