Open the Charging case (5) and take out both earbuds to switch on and pair your Earphones Urban 4 TWS. You can also press and hold the Multifunction button (R) (2) and (L) (1) for 2 seconds. At this point, the light on each earbud flashes and both earbuds pair automatically. This process usually takes 15 seconds. When the Status indicator (4) on an earbud flashes green and red, you will be able to pair your Earphones Urban 4 TWS with your smartphone.

If you only hear sound coming out from one earbud, disconnect them from the smartphone. Put the earbuds back into the Charging Case and tap 3 times each earbud to reset them (the earbuds flash green when the reset has been performed correctly). Once you've done this, repeat the setup process. Make sure the connection between both earbuds has been established successfully before pairing them with your smartphone.
