4. Perform a Reset
Some issues can be resolved by performing a reset on the headphones. Refer to the user manual or manufacturer’s instructions for the specific reset procedure for your Koss Porta Pro model.

Advanced Repair Techniques
For more complex issues or hardware failures, advanced repair techniques may be necessary. However, it’s essential to proceed with caution and consider the warranty status of your Koss Porta Pro headphones before attempting any repairs. Here are some advanced repair techniques for common issues:
1. Driver Replacement
If one or both headphone drivers are damaged or non-functional, you can attempt to replace them yourself. Here’s how:
- Identify the Driver: Open the ear cup housing to access the headphone driver. This may require removing screws or prying open the housing carefully.
- Disconnect the Old Driver: Carefully detach the wiring connector from the old driver.
- Install the New Driver: Connect the wiring to the new driver and secure it in place within the ear cup housing.
- Test the Headphones: Once the new driver is installed, test the headphones to ensure that both channels are functioning correctly.
2. Cable Replacement
If the audio cable is damaged or faulty, you can replace it with a new cable. Here’s how:
- Identify the Cable Connection Points: Determine where the cable connects to the headphone drivers and audio jack.
- Remove the Old Cable: Disconnect the old cable from the headphone drivers and audio jack. This may require desoldering or cutting the existing connections.
- Install the New Cable: Connect the new cable to the headphone drivers and audio jack, ensuring a secure connection.
- Test the Headphones: After installing the new cable, test the headphones to ensure that audio is being transmitted properly.
3. Internal Wiring Repair
If there are issues with the internal wiring of the headphones, you may need to perform internal repairs. Here’s how:
- Access the Internal Components: Open the ear cup housing to access the internal wiring and circuitry. Exercise caution to avoid damaging any components.
