How do I set up True Wireless Stereo on Beolit 20 without using the Bang & Olufsen app?

To set up stereo pairing manually, first press and hold the Bluetooth button on the first speaker for 5 seconds until the light indicator turns white. Wait for 20 seconds until a sound prompt is heard. Then perform the same operation on the second Beolit 20 or Beolit 17. Both devices will then make an audible cue to indicate that they are connected.
