First pairing
This device features "Google Fast Pair", which will allow you to pair them very easily. When you activate Bluetooth on your device and take the headphones out of their base, a message will appear on your smartphone's screen to connect them.
The traditional way is explained here:
Take the headphones out and wait 5 seconds for them to pair with each other.
To make a first connection to the SPC BOOST PRO via Bluetooth, you will need to activate the Bluetooth connection on your device. Once this connection is activated, you will have to search for your SPC BOOST PRO in the list of detected Bluetooth devices.
Once selected, the headphones will emit a "connection established" prompt.
