Soundbuds Surge Operation

How can pressing and holding the play button for 3 secs both turn the Anker Soundbuds Surge Off and put it in pairing mode? This is on page 01 and 02 of the english manual(which does not seem to be on the website.

Im trying to figure out how to put them in standby mode so they can be not plugged into the charger when not in use.

They turn off automatically when not in use.
