Well, you saw my thoughts...HEX has a smoother, more neutral tone than HE1K (i.e. no rough treble spot). I think jexby heard the same? Personally, I think I preferred the T50RP MK3 tone over the HEX (again, QUICK LISTEN, SHOW CONDITIONS, HEX from PHONE), but I'm guessing the HEX has a more capable driver. T50RP MK3 shit all over the Ether Closed I heard.
