8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Earbuds not pairing with device | Bluetooth off, earbuds not in pairing mode, device already connected to another earbud. | Ensure Bluetooth is on. Place earbuds in case, close, then reopen to re-enter pairing mode. Forget "Sleep" from device's Bluetooth list and re-pair. |
| Earbuds not charging | Poor contact with charging pins, faulty cable/adapter, case battery empty. | Clean charging contacts with a cotton swab and alcohol. Try a different Type-C cable and USB power adapter. Ensure charging case is charged. |
| No sound or low volume | Volume too low on device/earbuds, earbuds not properly seated, connection issue. | Increase volume on both your device and the earbuds. Re-seat earbuds in your ears. Reconnect Bluetooth. |
| Noise cancellation not effective | Misunderstanding of noise cancellation type, improper fit. | The CCA Sleep earbuds feature passive noise cancellation, which relies on a snug physical seal. They do not have Active Noise Cancellation (ANC). Ensure a proper fit with the correct ear tip size. |
