Using for Swimming
When using the headphones for swimming, it is essential to switch to MP3 Mode. Bluetooth signals do not transmit effectively through water, so streaming music via Bluetooth will not work reliably underwater. Ensure your desired music is loaded onto the 32GB internal memory before entering the water.

- Storage: Store the headphones in a cool, dry place away from direct sunlight and extreme temperatures.
- Charging Port: Ensure the magnetic charging contacts are clean and dry before charging to prevent corrosion.
- Avoid Impact: Do not drop or subject the headphones to strong impacts, as this may damage internal components.
