- Using a soldering iron, melt a piece of tin at each splice to firmly bind the fittings;
- Make an electrical rubber sheath to protect cuts;
- Wrap the cable connections in the sheath and heat with a thermal device so that the sheath shrinks.
Repair the jack plug
Often, it is the jack that suffers from somewhat brutal handling.

- Store the cables neatly.
The main cause of headphone malfunction is a cut in the wires. To avoid repairing audio equipment, wind the wire in a figure-eight fashion before placing it in the case.
- Regularly clean the headphones.
When in use, the headphones are exposed to various dirt and grime such as earwax, dust, gel, perspiration, or hair products. For optimal performance, it is important to clean the headphones after each use.
