How do I initially pair my A90 Pro earbuds with my phone?

First, ensure both the earbuds and charging case are fully charged. Take both earbuds out of the case and they will power on and start pairing automatically. Then enable Bluetooth pairing mode on your phone, search for and select 'A90 Pro' to connect. You should hear a voice prompt 'Connected' when wearing the earbuds. (Page 6)
