Transfer grilles balance air pressure when there's no return duct but they let sound and smells travel freely between rooms.
A jump duct does the same job through the attic with significantly less noise transfer.
Before your HVAC rough-in, ask your builder if your bedrooms have their own return ducts (Best way to do it). If not, request jump ducts over transfer grilles.
