edba2000 how is the sound characterestic? because you didnot use any crossover how does the iem behave on complex tracs. Did you notice any phase shifts or overlapping of frequencies?
All I can say is that the first listening test was disappointing!!
Now, after some "burn in" hours they are much better. I hope to get even better SQ after 50 hours...
The sound is very balanced. The bass is not exaggerated, the amount is enough and very well defined (but clearly not for bassheads). Mids are enjoyable and the best of this design (IMHO). As you can see, I have used a grey filter, I think it's enough to cut some of the Mids/Highs. I still need to find some more tracks with interesting highs, to compare with my Beyerdynamic DT 880.
About the complex tracks: I need some more time to test some "Dave Matthews Band" tracks. Do you want me to test some specific track?
