- Enable Bluetooth on your smartphone, tablet, or other Bluetooth-enabled device.

- Now, pair your Bluetooth device with the primary speaker ("TELLUR Obia") as described in section 5.1.
- Audio will now play in stereo through both speakers.
- To disconnect TWS, press the TWS (∞+) button on either speaker.
