Troubleshooting
| Problem | Possible Solution |
|---|---|
| No power/Won't turn on | Ensure the headphones are fully charged. Connect to the charger and check the LED indicator. |
| Cannot pair with phone | Make sure the headphones are in pairing mode (flashing red and blue LED). Turn off and on your phone's Bluetooth. Forget the device in your phone's Bluetooth settings and try pairing again. |
| No sound or low volume | Adjust the volume on both the headphones and your connected device. Ensure the transducers are positioned correctly on your cheekbones. |
| Bluetooth disconnects underwater | This is normal. Bluetooth signals do not transmit well through water. For swimming, use the internal 32GB memory (MP3 mode). |
| Cannot play music from internal memory | Ensure music files are in supported formats (MP3/WAV/FLAC/AAC/WMA) and transferred correctly. Double-click the multi-function button to switch to internal memory mode. |
| Poor sound quality | Ensure proper fit and placement. For swimming, using earplugs can enhance sound clarity. |
