How do I reset the A90 Pro earbuds when I can't find or connect them?

Put both earbuds back into the case, close the cover for 5 seconds, then take them out and try to reconnect. If that doesn't work, delete 'A90 Pro' from your phone's Bluetooth list, place earbuds back in the case for 5 seconds, take them out, put them in your ears, and quickly tap both earbuds five times until you hear 'Power off,' indicating a successful reset. Then place them back in the case for 5 seconds and reconnect. (Page 15)
