EQ Switch

- EQ 2 (Balanced): Offers a more balanced sound profile with crisp mids and clear highs, suitable for acoustic, classical, and vocal-centric music.

Maintenance
To ensure the longevity and optimal performance of your Marshall Mode EQ headphones, follow these maintenance guidelines:
- Cleaning: Regularly wipe the earbuds and cable with a soft, dry cloth. For ear tips, remove them and clean with mild soap and water, then dry thoroughly before reattaching.
- Storage: When not in use, store your headphones in a clean, dry place. Avoid extreme temperatures and direct sunlight. The tangle-resistant cable helps prevent knots, but gentle coiling is recommended.
- Cable Care: Avoid sharp bends or excessive pulling on the cable, especially near the connectors and earbuds, to prevent internal wire damage. The L-shaped jack is designed for durability, but proper handling is still important.
- Ear Tip Replacement: If ear tips become worn or lost, use only genuine Marshall replacement tips to maintain sound quality and fit.
Troubleshooting
If you encounter issues with your Marshall Mode EQ headphones, refer to the following common solutions:

| Distorted sound | Lower the volume on your device. Ensure the ear tips are clean and properly fitted. Test with another audio source. |
| Microphone not working | Ensure the 3.5mm jack is fully inserted. Check your device's settings to ensure the correct microphone input is selected. Test the microphone with another application or device. |
