Setup
Wearing the Earbuds
To wear the earbuds, gently rotate the ear hooks along the back of your ear until they are comfortably positioned. Ensure the earbuds sit securely without causing discomfort. For added security during active use, attach the detachable neckband.

Connecting to the Soundcore App
The Soundcore app enhances your listening experience by offering sound effects customization, control remapping, and other settings. Download the Soundcore app from your device's app store. Open the app and follow the on-screen instructions to add your AeroFit Pro headphones.
Enabling LDAC for Higher-Quality Audio
For an immersive audio experience with rich detail, enable LDAC in the Soundcore app. Navigate to the sound effects settings within the app and select the LDAC option. This will transmit three times more data than standard Bluetooth for enhanced sound quality. Note that LDAC is compatible with Android devices.
Dual Connections (Multipoint)
The AeroFit Pro supports dual connection, allowing you to switch seamlessly between two Bluetooth devices. To enable this feature, open the Soundcore app, go to settings, and select "Dual Connections" > "Enable Dual Connections" > "Connect New Device". If you need to play audio from the second device, pause the audio from the initial device first.

Maintenance
Cleaning
The detachable neckband can be cleaned by rinsing it with mild temperature, clean water. Ensure the neckband is completely dry before reattaching and using it again. The earbuds themselves are not washable; clean them with a dry, soft cloth.
Water Resistance
