Well, I guess in the end, I picked out the X10's because I found them for $160, but I certainly would've bought the Audio Technica's...if I could find them without spending the equivalent of spending for SE530's or getting the triple.fi's reshelled. In any case, thanks guys!
Impression: As noted before, the sound is rather warm to me, but the bass is pretty punchy and "fast", but compared to the Westone's I tried, it's missing something towards the high end. Ironically, they're so small that when I used the small double-flanges, I think they drove right into my ear, and though they do provide a seal, I don't know if it's the kind of seal that's giving me a good amount of bass, shrug, I'll keep testing with tips, but yea, really comfy and small (unless you shove em too far in your ear, real possibility with these earphones)
