Amazing soundstage for IEMs, these give Sennheiser HD 598 and Sony MDR-CD3000 (normal cans with great soundstage) a run for their money. And they're IEMs. Sound is on the dark side, I wouldn't mind having it a bit brighter, but they are still detailed. Bass is good enough.   My favorite IEMs at the moment due to the impressive weight, depth and height of soundstage, as well as positioning (try some binaural tracks of Dr. Chesky).   Build quality is average. No cable strain relief, etc. Packaging is good, although most tips are bad. Definitely...
