Maintenance and Care
Mack's Ultra Soft Foam Earplugs are designed for single or limited use depending on hygiene and condition. For optimal performance and hygiene:
- Inspect earplugs before each use for dirt, damage, or hardening. Discard if compromised.

Troubleshooting
If you experience issues with your earplugs, consider the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Earplugs do not block enough noise. | Improper insertion or incorrect size. | Ensure earplugs are rolled tightly and inserted deeply into the ear canal as per operating instructions. Pulling the outer ear up and back helps straighten the canal for better insertion. |
| Earplugs feel uncomfortable or cause pain. | Not inserted correctly or ear canal sensitivity. | Re-insert the earplug carefully, ensuring it expands gently. If discomfort persists, you may have sensitive ear canals; consider consulting a healthcare professional. |
| Earplugs fall out easily. | Insufficient expansion or improper fit. | Hold the earplug in place longer after insertion to allow full expansion. Ensure the ear canal is straightened during insertion. |
