Any recommendations for ~$150 IEM's?

[Geo212]

I'm in the market for a new set of IEM's, and I'd really like some recommendations to kick off my search. I'm looking for the absolute most balanced/neutral sound signature I can get for around $150. I'm replacing my good old pair of ECCI PR401's which tragically kicked the bucket a few weeks ago, so I'm looking for a sound signature similar to or better than (I'm hoping quite a lot better, considering the expected price differences) that of the PR401's.

For reference, I mainly listen to electronic music, but my music library is quite diverse, consisting of everything from Owl City to The Beatles. Because of this, balance and adaptability are key to me in headphones (I love my DT 880's to death). I'd like decent sound isolation, too, but I'm pretty sure any half-decent IEM has pretty fair isolation; I'm honestly mostly worried about the sound signature.

I greatly appreciate the assistance!

Ah, yeah, I completely forgot that existed; thanks for reminding me!

After reading the reviews in my price range, I'm trying to decide between the Etymotic Research HF5's and the VSonic VC1000's. Given the neutrality and linearity of the HF5's, I think I'm leaning toward those. The especially good sound isolation also sounds pretty appealing.
