Troubleshooting:

If the issue persists, reset the earbuds by deleting the Bluetooth name on the device, turning off Bluetooth, placing the earbuds back in the charging case, reopening the case, and pressing the button until the red LED flashes 3 times.

Warm Tips:

1. For the first-time use, please fully charge the earbuds and charging case. If the earbuds don't light up when opened, they need to be charged.
2. If the earbuds only light up blue, it means the "ACA-i21" Bluetooth has connected to a device in your home.
3. If the earbuds flash blue and red, it indicates they have entered pairing mode, and you can connect them to your phone by searching for "ACA-i21".
