Maintenance
- Cleaning: Use a soft, dry cloth to wipe the exterior of the headphones. For ear cushions, a slightly damp cloth can be used, but ensure they are completely dry before next use. Do not use harsh chemicals or abrasive cleaners.
- Storage: When not in use, store the headphones in a clean, dry place. Utilize their foldable design for compact storage, which also helps protect them from damage.
- Cable Care: Avoid sharp bends or excessive pulling on the cable to prevent internal wire damage. The cable is designed to be tangle-resistant for ease of use.

Troubleshooting
| Problem | Possible Cause | Solution |
