9. User Tips
- Optimal Sound: For the best sound experience, ensure the bone conduction transducers are placed firmly on your cheekbones, just in front of your ears.
- Swimming Mode: When swimming, it's recommended to use the built-in 32GB memory for music playback rather than Bluetooth, as Bluetooth connectivity can be unreliable underwater.
- Comfort: Experiment with the adjustable elastic strip to find the most comfortable and secure fit for your head size and activity.
- Awareness: The open-ear design allows you to stay aware of your surroundings, which is crucial for safety during outdoor sports like running and cycling.
