He's referring to the Super.Fi 5, not the Super.Fi 5 Pro (which was indeed a dual-driver BA in-ear with kind of "Triple.Fi 10-shaped" bodies).
The regular Super.Fi 5 was a top-firing single-BA in-ear with the same body shape as its successor, the UE600. I don't know if there are any tuning changes (dampers, impedance), but the connector has changed (angled vs. the previous straight one) and of course the packaging.
The regular Super.Fi 5 gets overlooked way too often.
