I really need to burn them in, but so far I'm on the fence with them. I think I need an amp or good DAC/amp for them. They're absolutely terrible sounding on my Macbook, I haven't tried them with my iPod yet, and they're pretty decent from my HT Omega Striker on my computer. So far I've noticed a slight bass emphasis, mildly muted mids with the HT Omega (severely muted with the Macbook), and highs that tend a little closer to shrill than I like (but I'm super sensitive to high frequencies). In some ways they're better than my AD700s and in some ways they're a little worse. With a good neutral amp, they may become more balanced.
I'll have to see if burn in makes them better. They're not bad at all, they just really need a good DAC/amp paired with them from what I've seen so far.
