As discussed before, the fear/claim is that the bad guys have developed techniques that make the devices work for a short period of time (small battery) while still containing explosive material. Difficult to see how that would work with, say, my Bose earbuds, but ... logic doesn't necessarily apply here. I can also easily take much more than 100 ml of a liquid onto a plane.
