6. Waterproof Usage (IPX8)
These headphones are rated IPX8 waterproof, meaning they can be submerged in water up to 2 meters deep for 1 hour. This makes them ideal for swimming, showering, and other water-based activities.
Important Considerations for Swimming:
- Use MP3 Mode: Bluetooth signals do not transmit effectively underwater. Always switch to MP3 mode before entering the water to ensure uninterrupted music playback.
- Use Earplugs: For optimal sound quality and to prevent water from entering your ears, use the provided earplugs while swimming.
- Drying: After use in water, gently shake off excess water and allow the headphones to air dry completely before charging or using them in Bluetooth mode.
