Don't forget to compare to your Bravados as well!
...I received my MD+ IEMs a few days ago and after 20+ hours burn, I think the MD+ is more articulate and airy than both the GR07 BE and IT01 and that it has a wider soundstage. In comparison to the MD+, the IT01's highs sound grainy and its lower mids and bass are less controlled (to the point of being woolly). However, the lower bass and especially the sub bass on the IT01 is stronger (in a good way) than the MD+ to the point where I find EDM more enjoyable on the IT01. So far, I think the MD+ is a better IEM than the IT01 except when I need to feel sub bass - I'm hoping the MD+ will gain more sub bass with use (or burn-in).
With regard to comfort, the MD+ are the most comfortable IEM in my limited collection. I rolled eartips (Spinfits, Complys, Sybios) and still ended up preferring my go-to Spiral Dots.
