I've used my KZ ATR for 3-4 days,and I want to say that it's amazing!
Originally,I'm using a $20 Audio-Technica earphone(which is terrible in it's price range).Changing it to ATR is a major step up for me!Compare to the SE215 from my friend,it has a similar soundstage(but SE215 separation is a bit better).For the bass part,ATR simply crushed the SE215 with a large amount of bass and it's much more detail compare to SE215 which sounds muffled(maybe because of the use of foam tips).
Mid-frequency is certainly not the best in ATR.It sounds flat as it has a slightly V-shaped frequency.Still,it's better than SE215 as it's more detail.
Treble is better than I expected.It never gets super sharp compare to some ATH earphone(like my $20 one).However,I found it satisfied when listening to female vocal.
Overall,compare to SE215,this is definitely a better deal for me.
However,everything has two side.The size of ATR is quite huge and it's hard to adopt to it.Also,the cable looks unattractive and super soft,which makes this earphone (maybe) not so durable.However,you can always buy ATR FOR around $5.So it's no big deal
BTW,this is my first post in Head-FiWelcome everyone !
Please try KZ "starline" silicone tips with ATR - they make ATR sound more coherent and balanced. Also detail, clarity and separation is slightly improved.
