3. Setup and Fitting
Proper fitting is crucial for optimal noise reduction and comfort. The ECLEAR Earplugs feature a thin design and soft silicone ear tips that conform to the ear canal.

6. Troubleshooting
If you experience issues with your ECLEAR Earplugs, consider the following:
- Poor Noise Reduction: Ensure you have selected the correct ear tip size for a snug fit. The earplug should feel secure in your ear canal without causing discomfort. Re-adjust the earplug, making sure the d-shaped part is properly seated.
- Discomfort: If the earplugs cause discomfort, try a smaller ear tip size. Prolonged discomfort may indicate an improper fit or sensitivity to the material.
- Earplugs Falling Out: Verify that the earplugs are inserted correctly and that the d-shaped part is securely positioned in the ear's hollow. Experiment with different ear tip sizes to find the most stable fit.
