Common questions about manuals, registration, and support for this brand.
Take both earphones out of the charging case. They will automatically turn on and pair with each other. Then, enable Bluetooth on your phone, search for the earbud model (e.g., S41, S20), and tap to connect.
Place both earbuds back into the charging case and close the lid. Take them out again to see if dual-ear mode restores. If not, try deleting the pairing record on your phone and re-pairing the device.
Place the earbuds into the charging case to automatically charge them. The case itself can be charged using the provided USB cable connected to a standard 5V adapter or computer USB port.
Stuttering can be caused by interference from Wi-Fi routers, other Bluetooth devices, or large physical obstacles. Try moving closer to your device or away from areas with high wireless interference.
