I would say that those two that you have listed are pretty good IEM at what they do. The Yamaha has a nice and warm sound that is not fatiguing at all, the fit could be a little problematic though (I recalled having issues getting a good fit, so YMMV). As for the JVC, they belong to what you would label as "fun" signature. The V-shaped frequency response emphasized the two ends of the spectrum to give songs that bit of a kick and energy.
GR07BE is a good all rounder I have to admit. I enjoy mine a lot too. They give a nice boost to the lower end of the spectrum.
But if the primary purpose of your use is for movies, I would personally go with headphones since they will be more competent in presenting the auditory cues and that "surround the head" kind of feel when you are in a cinema.
