Bone Conduction Listening
The bone conduction technology allows sound to be transmitted through your cheekbones to your inner ear, leaving your ear canals open. This enables you to hear your audio while simultaneously being aware of ambient sounds, which is crucial for safety during outdoor activities like running or cycling.

Maintenance
Cleaning and Care
- Wipe the earphones with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Ensure the charging port is completely dry before charging to prevent damage.
- The skin contact areas are made of skin-friendly silicone material. Clean regularly to maintain hygiene.
Storage
Store the earphones in a cool, dry place away from direct sunlight and extreme temperatures. Avoid placing heavy objects on them.
Waterproof Guidelines
The earphones have an IP66 dust and waterproof rating, meaning they are protected against strong jets of water and dust intrusion. This protection is effective when the charging port cover is closed and the earphones are worn normally. They are resistant to rain and sweat, making them suitable for intense exercise. However, they are not resistant to hot water. The waterproof and dustproof effects are not permanent and may decrease over time due to daily wear and tear.

Troubleshooting
- Earphones not powering on: Ensure the earphones are fully charged. Press and hold the 'Volume +' button for 2 seconds.
- Unable to pair via Bluetooth:
- Ensure the earphones are in pairing mode.
- Check that Bluetooth is enabled on your device.
- For Xiaomi devices using MIUI Quick Connect, ensure your phone's MIUI system and Bluetooth version in settings are updated.
- Move the earphones closer to your device (within 10 meters).
- Audio latency during gaming/video: For Xiaomi users, enable the low-latency function on your phone and manually add required applications in 'Game Acceleration' settings. The latency effect is measured with Bluetooth aptX-Adaptive format connection.
- Issues with Dual Device Connection: The experience may vary between devices. When answering/hanging up calls on a phone, video playback on a computer may pause and resume synchronously, requiring player support.
- Sound leakage: The earphones feature a 360° enclosed directional sound cavity to suppress sound leakage. Ensure proper fit for optimal performance.
