- Optimal Comfort: Experiment with the earbud rotation to find the most comfortable fit, especially if you are a side sleeper. The ergonomic design is meant to provide a 'zero-sensation' experience.
- Maximize Sleep Mode: For an undisturbed night, ensure both earbuds are in Sleep Mode. Remember that touch controls are disabled in this mode, so plan your audio playback accordingly.
- Battery Management: Take advantage of the extended battery life by fully charging the case. For long trips or extended use, the 320-hour total sleep endurance can significantly reduce charging frequency.
- Sound Quality: For the best audio experience, ensure a snug fit in your ear canal to benefit from the dual-layer noise reduction and the 6mm composite diaphragm.
