I thought I was hearing things after having my NT01AX replaced today due to peeling of the chrome finish on the left earpiece.
They sound even better and bass is clearly nicer and more pronounced. I believe the previous pair was a MSY2 while this new one is MT3.
QC of the NT01AX is not that good though, cause this replacement set does have some other cosmetic flaws (but better than peeling gold chrome).
Well, I got the new NT01AX. Mine is also an MT3, yay! The bass does sound more pronounced, I actually preferred the lighter touch from before, but those highs and mids are just as delicious as I remember. Best news is that this unit has absolutely NO buzzing sounds my previous unit had. I am extremely happy! Looks like I am done with TWE for a long while, and actually with audio in general. I just don't feel like there is a better balance of sound quality, comfort and convenience at the moment, and I get my earbud and IEM versions done. It all feels so perfect!
