Well i got a chance to listen to this cans, this is my first ATH IEM and i don't have anything to compare but to my M50, and it's kind of a little less spacious than M50, and the bass is overpowering the others, the build looks pretty fragile, but the comfort is decent for an IEM, i think.. I had a chance to listen to Crossroad before, and i think CKP500 present more bass than that cans..  overall this is a decent cans i think, i don't know it's worth the money or not, since this is my first IEM so can't help it.   but overall i love this...

  When i first bought this headphones i feel like "What the hell did i paid this for?" The sound was like coming out of my $10 and i was disappointed, the urge to sell them piled up and i was desperately listen to my music with them (ATH M50 LE was my first over $100 headphones back then, i can't really tell what kind of sound deserve how much money), but after a few hours of burn in (more than 100 hours i think), i think "Man.. this headphones made a big difference." They are pretty good in my ears, the sound feels warm, and there are noticeable...
