How to use

Charge the case and earbuds before first use using the USB-C port or a compatible wireless charger. Remove the earbuds from the case to power on and enter pairing mode; use your device's Bluetooth settings or Google Fast Pair to connect. Use touch controls or the EarFun app to manage playback, calls, ANC modes and EQ presets. Place the earbuds with the 11-degree tilt into the ear canal so the oval acoustic port sits comfortably and securely for best sound and noise isolation.

Usage recommendations

For optimal ANC performance, select the adaptive mode in quiet or noisy environments and ensure a good seal by trying different ear tip sizes. Use the EarFun app to personalize EQ and touch controls, enable multipoint if you frequently switch between two devices, and keep firmware updated for improved stability and audio quality.
