Setup and Fit
The KPH14K headphones are designed for a secure and comfortable fit during movement. Follow these steps for optimal setup:
- Adjust the Headband: The KPH14K features a fully adjustable headband. Gently slide the earbud sections along the headband to achieve a snug yet comfortable fit over your head.
- Position the Earbuds: The unique side-firing design means the earbuds rest just outside your ear canal, allowing for important ambient awareness. Position them so the sound is directed towards your ears without blocking external sounds entirely.
- Connect to Audio Source: Plug the 3.5mm audio jack firmly into the headphone port of your audio device (smartphone, tablet, laptop, MP3 player, etc.). Ensure the connection is secure to prevent audio interruptions.

Operation
Once connected, operating your KPH14K headphones is straightforward:
- Volume Control: Adjust the volume directly on your connected audio device. The KPH14K headphones do not feature inline volume controls.
- Audio Playback: Begin playing audio from your device. The side-firing design provides clear sound while maintaining awareness of your surroundings, which is beneficial for outdoor activities or shared environments.
- Wired Connection: These headphones utilize a standard 3.5mm wired connection, ensuring a reliable audio experience without the need for batteries or Bluetooth pairing.
Maintenance
Proper care will extend the life and performance of your Koss KPH14K headphones:
- Cleaning: Use a soft, dry cloth to wipe down the headphones, especially after workouts, to remove sweat and dirt. For stubborn grime, a slightly damp cloth can be used, but ensure no moisture enters the earbud openings or the 3.5mm jack.
- Storage: Store your headphones in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cord by coiling it loosely when not in use.
- Cord Care: Do not pull on the cord to disconnect the headphones from your device. Always grasp the 3.5mm jack directly. Avoid sharp bends or excessive tension on the cable.
Troubleshooting
If you encounter issues with your KPH14K headphones, try the following solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose connection, device volume too low, incorrect audio output selected on device. | Ensure the 3.5mm jack is fully inserted. Increase volume on your audio device. Check device settings to confirm audio is routed to headphones. Test with another audio device. |
| Distorted Sound | Damaged cable/jack, audio source issue, volume too high. | Lower the volume. Test with another audio device and different audio files. Inspect the cable and jack for visible damage. |
| Uncomfortable Fit | Headband not adjusted correctly. | Adjust the sliding sections of the headband to find the most comfortable and secure position for your head. |
If problems persist after trying these steps, please contact Koss customer support for further assistance.
