7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Low battery, incorrect connection, volume too low, incorrect source selection. | Charge the device. Ensure headphones are fully plugged in. Check volume levels on both Tea Pro and source device. Verify correct input mode (wired/Bluetooth). |
| Bluetooth pairing issues | Tea Pro not in pairing mode, interference, previously paired device. | Ensure Tea Pro is discoverable. Turn off Bluetooth on other devices. Try unpairing and re-pairing. Restart both devices. |
| DSD files not playing correctly (iOS) | iOS DSD native support limitations, volume setting. | Ensure your iPhone's volume is set to maximum before playing DSD files. iOS typically uses DoP (DSD over PCM) up to DSD256, not native DSD512. Check your playback app settings. |
| Magnetic attachment not secure | Obstruction, phone case incompatibility, heavy headphone plugs. | Ensure the back of your phone and Tea Pro are clean. Use a MagSafe-compatible case. Note that some large 4.4mm plugs might cause slight lifting. |
| Device unresponsive | Software glitch, low battery. | Perform a soft reset by holding the Power button for an extended period (e.g., 10-15 seconds). Charge the device. |
