When the connection between the headphones is correct, both LEDs will light up at the same time. After a few seconds, the LEDs on one of the headphones will stop flashing (usually the left one) and the other will continue flashing.
You can proceed to link to your music player device through the Bluetooth connection.
To turn off you SPC ZION 2 PLAY, place them directly in the charging case, with the lid closed. They will be unpaired from the Bluetooth device and will turn off and start charging.
