Frustrating! Let's troubleshoot:
1. Check the charging cable and port for damage or debris.
2. Ensure the charging cable is properly plugged into both the headset and the charging source.
3. Verify the charging source is working (try charging another device).
4. Check the headset's charging port for corrosion or dirt (clean with a soft brush or cloth).
5. Try a different charging cable or adapter.
6. Check the headset's battery status (might be fully discharged; try letting it charge for a bit).
7. Restart the headset (sometimes a simple reboot resolves the issue).
8. If none of the above works, the battery or charging circuit might be faulty (consider contacting the manufacturer or a repair service).
Hope this helps!
