Every RE0 recommendation almost always recommends a headphone amp for them. So it might not be Hippo VB levels, but will they give a boost enough to be worth dishing out for the price of what the actual headphones themselves cost?
I will refer you to this post here: http://www.head-fi.org/t/538601/re0-amp#post_7263131
Short answer: no.
Most In ear phones as I said, don't improve all that much with amping, and certainly not enough to merit lugging around something that negates your portability.
