In reality nothing sounds that cold and detailed and that's what makes the er4s' presentation unrealistic but that's an issue with most analytical BA iems. But yeah, while something like the gr07 is made for the likes of stage monitoring with a slightly warm but neutral sound presentation the er4s is something that can give you the wow-factor depending on what music you listen to and some people will be a lot more impressed by it even though in reality it's just a completely different beast but not one that is particularly superior to the gr07.
Actually, if anything, the GR07mkII may have slightly more treble over mids, than the ER4S does, overall. In other words, the ER4S is slightly less tilted from mids to highs. You must keep in mind that I didn't listen to the stock GR07; I listen to it EQ'd. With my EQ setting, it's just as analytical and "cold" (I don't like these words) with the same treble quantity as the ER4S, and the ER4S still resolves more details effortlessly. The ER4S's presentation is incredibly realistic and moreso than the GR07, especially in the 3D soundstage, where each instrument has its own space and doesn't smear into other sounds as much, which also creates a clearer image.
What you're hearing as more decay, I think, is actually the GR07's greater bass quantity. However, if you EQ these phones to have the same flat bass response, it becomes clear that their decays are very similar; while ER4S still resolves more bass detail.
