Foldable prongs are not always helpful though. That’s true for non portable uses for the Amazon Echo Dot 2nd generation speaker, since this unit needs external power to work. In fact, foldable prongs can loosen over time and develop faulty connections. Thus, this loosening can cause poor operation and speaker cutouts. But 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. Indeed, they could cause lots of problems instead.
