Yeah it kind of reminded me of the sound signature of the HE1000, just in an IEM version. I can see acoustic being a highlight.
Ooh, that's a good way to describe it for me since I've heard the HE1K. If that's the case, than as an IEM, it wouldn't be my perfect all-rounder for the exact reason that @Currawong has a slight problem with it. Would be great if I were just sitting around not doing anything, but when movement is involved, I'd like to have more low-end grunt. And since I listen to a lot of EDM and my taste for bass is certainly north of flat, there needs to be much more bass than I'm getting out of something like the Nova, for example.
I'm due to try the foam tips again to see if that balances them better for that kind of music. It's rather funny, because before I was trying to get them to be less bass strong. This is why I tend to be slow writing (or recording) IEM reviews.
