Keep in mind the newer revised 1Plus2s are a completely different beast. Take a look at the Tralucent Audio thread and maybe even keep it in mind. If indeed this IEM is more detailed than HD800 then you can bet your dollar the treble will be killer on it. The review units won't be going out til sometime this week or the beginning of next week. :)
I have the K3003 and listen to my brother's EX1000 these days.
I'll specify from the start that I'm very sensitive to high frequencies. I think the AKGs are on another level in terms of detail and they also isolate better, but are more fatiguing. However, the Sonys have a bit more bass, not sure if the level of detail in the lows is better, but they have a bit more bass quantity, and I definitely like that (I'm not a bass head, I have the IE80s and I don't listen to them). They also have a bigger soundstage.
Going from the AKGs to the Sonys is a relaxing experience to these ears. If some find them too bright I suppose it's because of listening to high levels. I personally listen to low levels, I have very sensitive ears, and there's no harshness on EX1000 when listening at reasonable levels. They are very serious IEMs. On the other hand I rarely listen to K3003 without eq-ing the 5.5kHz peak.
