Yeah, I also agree with you but then again what do I know I only own them
Seriously people having opinions on stuff they have no clue about really gets me worked up because it's so totally meaningless.
Anyway the transparency in the midrange is just magic imo, it's so clean sounding. I also find it impossible to understand that someone would call the treble harsh but YMMV and obviously does in this case.
My least favorite part of them is the bass which is a bit on the soft side making it slightly boomy occasionally. Stil they're very good in most ways and not bad in any for my preference and value for money is just through the roof.
Edit: I must say that my last three IEM's (****, BIE and Z05A ) are all extremely pleasing to me which is nice after a few disappointing purchases lately, especially the F300.
