Maintenance
Cleaning
Regularly clean the earbuds and charging case with a soft, dry cloth. For the ear cushions, you may gently wipe them with a damp cloth and mild soap, ensuring they are completely dry before reattaching. Avoid using harsh chemicals or abrasive materials.
Storage
When not in use, store the earbuds in their charging case to protect them and ensure they remain charged. Store the case in a cool, dry place away from direct sunlight and extreme temperatures.
Water Resistance (IPX4)
The earbuds are rated IPX4, meaning they are resistant to splashing water from any direction. This makes them suitable for light rain or sweaty workouts. However, they are not designed for submersion in water. Avoid exposing them to strong jets of water or prolonged immersion.
