So lets just say you are farming at The Thousand Maws of Toto-Rak which is a level 24 dungeon and you sync down from lets say level 40....the item then activates since you are in that dungeon as a level 24! It only stops working once you step outside the level synced content. The same applies to the Earring. If you are level 52 for example and put on the earring and do a synced level 50 dungeon...the earring will activate since you are level 50 inside that instanced dungeon and all xp earned will also apply the bonus xp until you leave and un sync!
But if you're synching down from 40 to do Tota Rok, you're going to be level 27, not 24.
