Just got the KZ10s from Ali today. First impressions are pretty good. Wide and spacious. Lots of low end rumble. Sub bass is quite good. Treble is fine for me. Sounds a bit dark to me, but I like it. No sibilance at all. Mids are a bit off. Male vocs sound thin and scratchy. Not a deal breaker at all though. Eq helps a bit. Things excel at EDM and modern hip hop/trap stuff. I personally find them quite comfortable and the stock tips made a nice seal and were fine. Have a ton of tips but loathe tip rolling. Anybody have some recommendations? Also got the EDR1 sent to me free for buying the KZ10s, but have not opened yet. been wearing the 10's all night. Listened to Belly, Hellecopters, Bad Religion, Awolnation, 12 girls band, Chronixx, Rebelution, Apathy, Blackalicious, Stevie Stone, and Silkie through Cayin N5 and Sony NW-A45. I like these much better then the ZST's.
