How do I pair the A90 Pro earbuds with my phone for the first time?

Take both earbuds out of the charging case and they will power on and start pairing automatically. Then enable Bluetooth on your phone, search for 'A90 Pro', and select it to connect — you should hear a voice prompt saying 'Connected' when wearing the earbuds. Make sure both the earbuds and charging case are fully charged before first use. (Page 6)
