Connecting the Bluetooth headphones is very easy ex works: After you insert the Earbuds into the charging cradle for the first time and take them out again, they automatically switch to pairing mode. You then only have to connect the headphones via the settings of your smartphone.
However, this only works like this for the first pairing.
Sony WF-1000XM3: pairing more devices via Bluetooth
Once a device was already connected to your WF-1000XM3, the connection via Bluetooth works a bit differently.
1. Take the headphones out of the charging cradle and insert them into your ears.
2. The Earbuds each have a round touch sensor. Press and hold the touch sensor of both Earbuds simultaneously for about 7 seconds. Once the earbuds are in pairing mode, you will hear “Bluetooth Pairing” from one of the earbuds.
3. Now you can connect your WF-1000XM3 in the Bluetooth settings of your smartphone, tablet or notebook. If you need to enter a password (or passcode), type in 0000.
