Setup
- Choose Your Earplugs: Select either the foam or silicone earplugs based on your comfort preference and desired Noise Reduction Rating (NRR). The foam earplugs provide a 29dB NRR, while the silicone earplugs offer a 27dB NRR.
- Attach Earplugs: Securely attach the chosen earplug tips to the earbud speakers. Ensure they are firmly seated to provide optimal noise isolation and sound quality.
- Insert into Ears: For foam earplugs, gently roll and compress the foam tip before inserting it into your ear canal. Hold it in place until it expands to create a seal. For silicone earplugs, simply insert them into your ear canal until a comfortable and secure fit is achieved.
- Connect to Device: Plug the 3.5mm audio jack into your audio device (e.g., smartphone, MP3 player, radio).
- Adjust Cable: Use the included cable clip to secure the cord to your clothing, reducing snagging and pulling.

Operating Instructions
Once properly set up, the Plugfones Guardian Earplug Headphones are ready for use:
- Audio Playback: Begin playing audio from your connected device. The Hi-Fi tuned speakers are designed to deliver clear sound even in noisy environments, thanks to the noise-isolating earplug design.
- Noise Reduction: The earplugs provide passive noise reduction, protecting your hearing from loud sounds while allowing you to listen to audio at safe levels.
- Volume Control: Adjust the volume directly from your audio device.

Maintenance
To ensure the longevity and hygiene of your Plugfones Guardian Earplug Headphones, follow these maintenance guidelines:
- Cleaning Earplugs:
- Silicone Earplugs: Detach from the earbuds and wash with mild soap and water. Rinse thoroughly and allow to air dry completely before reattaching.
- Foam Earplugs: Foam earplugs are generally disposable and should be replaced when they become dirty or lose their elasticity. Do not wash foam earplugs as this can compromise their noise reduction properties.
- Cleaning Earbuds and Cable: Wipe the earbud bodies and cable with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, store your Plugfones Guardian in the provided waterproof storage case to protect them from dust, dirt, and moisture.
- Sweat Resistance: The headphones are sweat-resistant, but prolonged exposure to excessive moisture should be avoided. Ensure they are dry before storing.

Troubleshooting
If you encounter issues with your Plugfones Guardian Earplug Headphones, consider the following common solutions:
- No Sound or Low Volume:
- Ensure the 3.5mm audio jack is fully inserted into your device.
- Check the volume level on your audio device.
- Test the headphones with a different audio device to rule out device issues.
- Inspect the cable for any visible damage or kinks.
- Poor Noise Isolation:
- Ensure the earplugs are correctly inserted and form a tight seal in your ear canal.
- Try the alternative earplug type (foam or silicone) to see if it provides a better fit and seal.
- Replace old or worn-out foam earplugs.
- Discomfort During Use:
- Experiment with both foam and silicone earplugs to find the most comfortable fit for your ears.
- Ensure you are using the correct insertion technique for foam earplugs (rolling and compressing before insertion).
