Setup Guide

1. Charging the Earbuds and Case

Before first use, ensure both the earbuds and the charging case are fully charged.

• Place the earbuds into the charging case.
• Connect the Type-C charging cable to the charging port on the case and to a power source.
• The indicator lights on the case will show charging status. A full charge takes approximately 1 hour.
• The charging case can fully recharge the earbuds multiple times, providing up to 32 hours of total playtime.

2. Bluetooth Pairing

To connect your earbuds to your device:

1. Ensure the earbuds are charged and inside the charging case.
2. Open the charging case. The earbuds will automatically enter pairing mode, and indicator lights will flash.
3. On your smartphone or Bluetooth-enabled device, go to "Settings" and enable Bluetooth.
4. Search for "LY9 pro" in the list of available devices.
5. Select "LY9 pro" to connect. Once connected, the indicator lights will stop flashing, and you may hear a confirmation tone.
6. Allow the device to connect if prompted.

3. Wearing the Earbuds

The LY9 pro earbuds feature a "Shark ear wing design" for ergonomic comfort, especially for sleep.

• Gently insert each earbud into the corresponding ear canal (L for left, R for right).
• Adjust the earbud until it feels snug and comfortable. The small body is designed to fit well without protrusion, preventing pressure when sleeping on your side.
• Proper fit is crucial for effective physical sound insulation and noise blocking.

Operating Instructions

Earbud Controls (Touch/Tap)

The earbuds themselves may have basic touch controls for media playback. Refer to your device's Bluetooth settings or the remote control section for comprehensive control.

Remote Control Functions

The charging case doubles as a remote control, allowing you to interact with your device without touching it. This is particularly useful for social media, e-reading, and photography.

Remote Control Connection (for advanced features like camera shutter)

For certain remote functions, especially camera control, you might need to ensure the remote is properly recognized by your phone's accessibility settings.

1. Press and hold the remote control (charging case) for three seconds until the indicator light flashes.
2. On your iOS device, navigate to "Settings" > "Accessibility" > "Touch" > "AssistiveTouch" and enable it.
3. If the camera button is invalid after initial setup, enter the shooting software interface, long press the camera button 2 without releasing it, and short press the direction key to move "pointer/dot" to the shutter circle range of the shooting software.
4. For iOS 15 and above, if tracking sensitivity has been adjusted, the dot needs to be moved back to its initial default position.

Note: The setting method for iOS system settings and camera button 2 may be invalid in some cases. Remote control connected to mobile phone Bluetooth, screen automatic rotation lock, and AssistiveTouch enabled are common requirements.

Special Features

• Sleep Aid & Noise Blocking: The ergonomic design and physical sound insulation help reduce external noise, providing a quieter environment for sleep.
• Intelligent ENC Call Noise Reduction: The built-in Environmental Noise Cancellation algorithm effectively filters ambient noise, ensuring clear communication during calls, even in noisy environments.
• IPX5 Water Resistance: The earbuds are designed to be life-level waterproof, making them resistant to sweat and light rain, suitable for sports and outdoor activities.

Maintenance and Care

• Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Do not use harsh chemicals or abrasive materials. For earwax buildup, gently clean the earbud mesh with a small, soft brush.
• Storage: When not in use, store the earbuds in their charging case to protect them from dust and damage. Keep the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life, avoid fully discharging the earbuds and charging case frequently. Charge them regularly, even if not used for extended periods. Avoid exposing the device to extreme heat or cold, as this can degrade battery performance.
• Water Resistance: While the earbuds are IPX5 water-resistant, they are not waterproof for submersion. Avoid exposing them to heavy rain, showering, or swimming. Ensure the charging port is dry before charging.

Troubleshooting

Earbuds not pairing or connecting:

• Ensure both earbuds are charged and placed correctly in the charging case.
• Turn off and on your device's Bluetooth.
• Forget "LY9 pro" from your device's Bluetooth list and try pairing again.
• Ensure the charging case has sufficient battery.

No sound or poor sound quality:

• Check the volume level on both your connected device and the earbuds (via remote control).
• Ensure earbuds are properly seated in your ears for optimal sound and noise isolation.
• Clean any debris from the earbud mesh.
• Try disconnecting and reconnecting the Bluetooth connection.

Remote control not responding:

• Ensure the charging case (remote) is charged.
• Verify the remote is properly connected via Bluetooth as described in the "Remote Control Connection" section.
• Check your phone's accessibility settings if using advanced features like camera shutter.

Earbuds not charging:

• Ensure the charging cable is securely connected to both the case and the power source.
• Try a different Type-C cable or power adapter.
• Clean the charging contacts on both the earbuds and inside the case.

User Tips

• For optimal sleep comfort, ensure the earbuds are gently but firmly placed in your ear canal. The "shark fin" design is specifically for this purpose.
• Utilize the remote control for hands-free operation, especially when relaxing or in bed, to avoid reaching for your phone.
• The ENC feature is primarily for calls; for general noise blocking during sleep, the physical fit is key.
• Remember to attach the watch strap to the charging case for easy portability and access to the remote functions on the go.
