During the charging process, you can check the battery charge level using the LED battery

The earphones can be charged 3 to 4 times in the charging case while on the move.
Pairing
The earbuds should not be more than 1 meter apart for pairing.
a.
Open the charging case and remove the earphones from the charging cradle. The earphones
flash blue and red alternately and connect to each other. When only one of the two earphones
is still flashing, pairing starts.

Open the Bluetooth settings on your device and wait until TF SPARK ONE is displayed in the
list of Bluetooth devices found.

Select TF SPARK ONE. As soon as the earbuds are connected to the device, you will hear a

For future use, the earbuds will automatically connect to your Bluetooth device as soon as the
earbuds are removed from the charging case. If you want to connect a new device, deactivate
Bluetooth on the last connected device and carry out steps a to c again. As soon as the earphones
are placed in the charging case, they switch off automatically. You can also disconnect the
Bluetooth connection manually by touching the touch field on the left or right earbud and holding it
