The CKW1000ANV has WAYY more bass, while the ex1000's bass is'nt boosted at all. They both a very realistic 3D-Soundstage: Wide, good depth and instrument separation.
The Sony's stage is still much wider, in fact, its the best I have heard and easily compares to open fullsize cans.
I think the CKW1000ANV has a bit more resolution, but the ex1000 sounds more accurate due to the flatter frequency line.
Both have annyoing treble though. The ex1000 can get really shrill, especially at semi-loud volume it pierces my ears. Hi-Hats are impossible to endure for me..
Whereas the Audio-Technica can get quite sibilant.. I dont mind that though.
Isolation is both mediocre.
Would love to try the CKM1000(hope they have the same good driver) or the NEW CKS1000. Really liking the CKW1000ANV so far, in fact it holds it's position as my favoure IEM/headphone.
