Foldable prongs are not always helpful.  That’s true for non portable uses for the Echo Dot 2, since this speaker needs external power to work. Foldable prongs can loosen over time and develop faulty connections. This can  cause poor operation and speaker cutouts. Now you are not likely to plug and unplug the Echo Dot 2 power cord much. So we feel that folding prongs would give little added value here.  In fact, they could cause lots of problems instead.
