Important Notes and Safety Information

• **Wearing**: Ensure the speakers are positioned on your cheekbones, not inside the ear canal.
• **Volume**: Avoid prolonged listening at high volumes to prevent discomfort and potential hearing damage. Use a medium volume whenever possible.
• **Situational Awareness**: Using headphones will affect your perception of surroundings. Exercise caution, especially in environments requiring awareness (e.g., cycling, running outdoors).
• **Water Exposure**: While IPX8 waterproof, avoid prolonged soaking in seawater or saltwater. Always rinse with clean water and dry the headphones, especially the magnetic charging port, after use in water or after sweating, to prevent corrosion.
• **Physical Handling**: Do not throw, sit on, or subject the headphones to violent impact or extrusion, as this can damage the electronic motherboard and battery.
• **Environmental Conditions**: Keep the headphones away from fire, high temperatures, freezing conditions, and harsh chemicals.
• **Children**: Not suitable for children under three years old due to small parts.
• **Disposal**: Do not dispose of as household waste. Take to an appropriate local electrical and electronic equipment recycling station.
• **Charging**: Only use approved chargers with the specified voltage and current (DC5V +/-0.25V, 100mA-500mA). Using other chargers may void the warranty and cause damage.

Disclaimer: The company does not assume responsibility for personal or property damage caused by violating these warnings.

User Tips

• **Pairing Issues**: If you encounter difficulty pairing with a new device (e.g., Samsung S24 Ultra), ensure the headset is in pairing mode (flashing Bluetooth icon) and your phone's Bluetooth is on and searching. Try restarting both the headphones and your phone.
• **Underwater Music Playback**: For swimming, it is highly recommended to use the built-in 32GB MP3 player. Bluetooth signals can be significantly attenuated or lost when submerged in water, leading to interrupted playback.
• **Post-Swim Care**: Always rinse the magnetic charging contacts with fresh water and thoroughly dry them after each use, especially after swimming in chlorinated or saltwater, to prevent corrosion and ensure longevity.

Troubleshooting

Problem: Headphones do not power on.

**Solution**: Ensure the headphones are charged. Connect them to a charger and check the display for battery status. Long press the Right Button for 3 seconds to power on.

Problem: Cannot connect via Bluetooth.

**Solution**:

• Ensure the headphones are powered on and in pairing mode (flashing Bluetooth icon).
• Make sure Bluetooth is enabled on your device and it is searching for new devices.
• Select "X10 (Bluetooth)" from the list.
• Try restarting both the headphones and your device.
• Ensure the headphones are not already connected to another device.

Problem: Music playback is interrupted or stops while swimming.

**Solution**: Bluetooth signal does not transmit well through water. For swimming, use the built-in 32GB MP3 player for local music playback. Switch to TF Card mode by double-clicking the Right Button.

Problem: Low battery warning or headphones shut down unexpectedly.

**Solution**: The battery level is low. Connect the headphones to a 5V 1A or 5V 2A charger immediately.

Problem: Charging port shows signs of corrosion.

**Solution**: Always rinse the magnetic charging port with clean, fresh water and dry it thoroughly after each use, especially after exposure to sweat, saltwater, or chlorinated water. This prevents mineral buildup and corrosion.
