Graphs don't always indicate the final sound. The treble is there but it seems to be there in a sibilant manner that for me is still present even using the deep fitting.
There is really no flawless Iem out there. K3003 can also sound bright.
i have ultrasone dj one pro. i love them, they sound bright, sibilant, but the treble extends to 19khz. at least i can hear it until then. the soundstage, is like, amazingly big. huge. the only headphone i heared to have a larger soundstage was hd800. so i enjoy bright, even a little sibilant treble. i hate distortions, like most of headphones i have tried cannot reproduce piano without distortion, some kind of clipping, i don't know what it is. ultrasone dj one pro seems to reduce that by a lot by having recessed mids. so i enjoy soundstage, treble, separation, and microdetails. like my dj one pro is almost like hd800 in this manner. amazing microdetail extraction. this is what i am searching for. the treble of ie8, which i own, for example is tamed, and too tamed for my tastes, i always have to eq the treble to stay at +6db at 10khz, +8db at 16khz and +12db at 20khz... to give an ideea of what i am searching for.
this is why i am afraid of iq, and k3003. i am afraid they might not have enough treble, soundstage, microdetail, separation, and other characteristics.
i would enjoy a more cold, bright, analytical, airy, immersive but sibilant and harsh treble, more than i enjoy dark warm and tamed. if you would have listened to dj one pro, someone which i gave them to listen took them off, after one minute and said that the treble is sibilant, and harsh, similar to hd800, but much more harsh, and a similar sibilance.
sorry for taking so much of your time, and thank you for helping me!~
