Setup
1. Ear Tip Selection and Fitting
For optimal sound quality and noise isolation, it is crucial to select the correct size ear tips. Your Symphonized NRG 3.0 headphones come with three sizes (S/M/L) of custom comfortable silicone ear tips.
- Experiment with each size to find the tips that provide a snug and comfortable fit in your ear canal.
- A good fit will create a seal that enhances bass response and effectively blocks out external noise.
- Gently insert the earbud into your ear canal and twist slightly until it feels secure.

- Insert the 3.5mm audio jack firmly into the headphone port of your device (e.g., smartphone, tablet, MP3 player, laptop).
- Ensure the connection is secure to prevent audio interruptions.

Maintenance
Cleaning Your Headphones
- Ear Tips: Regularly remove the silicone ear tips and clean them with a mild soap and water solution. Rinse thoroughly and allow them to air dry completely before reattaching.
- Earbud Grilles: Gently wipe the earbud grilles with a dry, soft cloth to remove any earwax or debris. Avoid using liquids directly on the grilles.
- Wood Housing: The real wood housing can be wiped with a dry, soft cloth. Avoid excessive moisture or harsh cleaning agents, as these can damage the wood finish.
- Cable: Wipe the cable with a damp cloth to remove dirt or oils.
Storage
To prolong the life of your headphones, store them properly when not in use.
- Your headphones come with an eco-friendly convenient carrying pouch. Always store your headphones in this pouch to protect them from dust, dirt, and tangling.

Troubleshooting
If you encounter any issues with your Symphonized NRG 3.0 headphones, please refer to the following common troubleshooting steps:
- No Sound or Intermittent Sound:
- Ensure the 3.5mm jack is fully inserted into your device's audio port.
- Check the volume level on both your device and using the in-line controls.
- Test the headphones with a different audio source or device to rule out a device-specific issue.
- Inspect the cable for any visible damage or kinks.
- Distorted Sound:
- Ensure the ear tips are clean and properly seated on the earbuds. A poor seal can affect sound quality.
- Lower the volume on your device; very high volumes can sometimes cause distortion.
- Test with another audio file or streaming service to check if the issue is with the audio source.
- Microphone Not Working or Poor Call Quality:
- Ensure the 3.5mm jack is fully inserted. Some devices require a specific type of 3.5mm jack for microphone functionality.
- Check your device's audio settings to ensure the external microphone is selected.
- Clean any debris from the microphone opening on the in-line control.
- Test the microphone with a different application or device.
- Earbuds Falling Out:
- Re-evaluate your ear tip size. You may need a larger size to achieve a secure fit.
- Ensure you are inserting the earbuds correctly, with a slight twist to secure them.
