2. Wearing the Earbuds
The SM828 earbuds feature an in-ear and neck-hanging design with a memorized cable for a stable fit.

Waterproofing Guidelines (IPX7)
The SM828 earbuds are professionally rated IPX7 waterproof, meaning they are protected against immersion in water up to 1 meter for up to 30 minutes. This makes them suitable for:
- Sweaty workouts
- Running in the rain
- Showering
- Climbing and other outdoor activities

Important Note:
- While IPX7 rated, it is not recommended for swimming or diving. The double pressure of water temperature and water pressure, especially in winter, and the disinfection powder in swimming pool water can damage the internal components and invisible rubber pads over time, leading to water ingress.
- Always ensure the charging port cover is securely closed before exposing the earbuds to water.
Maintenance
- Cleaning: Wipe the earbuds with a soft, damp cloth after use, especially after sweaty workouts. Ensure they are dry before charging.
- Storage: Store the earbuds in a cool, dry place away from direct sunlight and extreme temperatures. The memory wire design allows for automatic folding, making them portable and easy to store.
- Charging Port: Keep the USB Type-C charging port clean and free of debris.
