The E30 is quite similar to the E10, just less v-shaped with more balanced between midrange and bass, and less treble sparkle. I don't know if I would pick it over the SHE3580 either.
Regarding microphonics, the SHE3580 is pretty bad unless worn over-the-ear. You could even get some of those silicone cable guides to help keep the cable in place.

Got a UM3X. My ears are still in line with Joker's, as I find the review on them similar to what I hear.
One weird thing I have noticed is: how terrible the UM3X is off the Zodiac. Off my iPhone 4S, they're great. On the Zodiac, I can't take more than a few minutes. It's impressive that they're wideband enough to actually change between the two, but it's also annoying. The Zodiac shows the midrange to be especially overwhelming. My theory is that the Zodiac does a better job resolving spatial cues and places the vocalist front and center depth-wise. Most recordings are this way, and it comes off correct on speakers or headphones that can do depth, ie. HD800, HE-6, etc. But on the UM3X, the presentation area is relatively small, and so all this depth and spatial information is truncated to nothing but a massive midrange bump.
Anyway, as far as comfort goes, sound, etc, this is one purchase that I don't regret. It took a LOT of tip rolling to find tips that didn't make things too warm, liquidey, gooey, and treble recessed, but it was well worth it in the end.
What's the output impedance of the Zodiac? You really don't want a high output impedance for a BA monitor such as the UM3X.
Definitely not next, there's a number of things ahead of them in queue including some heavy hitters.

I don't know any audio terminology so bare with me. I've been using Bose IE2 headphones for about a year now but I'm not really satisfied with them. Vocals and instruments seem to get drowned out during band jams and choruses. What sort of headphones under $300 should I be looking at to fix this? I'm leaning toward GR07 headphones since those have a lot of good reviews.
Also, years ago I used to have some cheap Sony MDR-A35G headphones that made vocals sound like they were being sung live directly into my ear compared to sort of a distant tinny sound most other headphones have. I don't know if that was due to isolation or what but it was amazing and I'd like to have that back.
The GR07 is nicely balanced and resolving but it's not a forward-sounding earphone. An old Sony and a Bose in-ear may not be good enough data points for determining the type of sound you like - an earphone doesn't have to be forward-sounding in order to give you great vocal clarity and intelligibility but chances are neither the Bose nor the Sony can showcase that. If you do want your vocals forward and intimate you may want to go for a JVC FXT90 over the GR07, or one of the higher-end BA monitors such as the Final Audio FI-BA-SA.

joker thanks for your advice, i've already auditioned akg3003 coming from tf10(with white angel cables) and fx500 it really blown me away
my impressions of akg3003 using walkman z1000 with stock player are:
- price is too steep for price and performance ratio

- everything is clear and clean it's like a mixture of fx500 and tf10(with white angel cables)
- very good highs and well extended, clear mids, very good bass in quality and quantity, good timbre and almost same soundstage as fx500

still might go to miracle ciem which i think have better price and performance ratio (but not yet auditioned) while still saving up for it,
i'm planning to buy orthofon eq-5, do you think is it step-up coming from tf10(with white angel cables) and fx500?
just can't tolerate metallic tinge of tf10 and recessed mids of fx500 
your recommendation is highly appreciated
thank you sooo much,
I only have a stock TF10. The e-Q5 is a more balanced than that and than the FX500 as well. Definitely no recessed mids there. It's actually still one of the most 'pleasant' earphones I've heard, maybe not the best at anything but so refined and relaxed that wanted to listen to it instead of reviewing it.
