Got a pair of these recently, only about 80 hours of pink noise burn in on them so far, so I'm holding off on commenting (probably until the often stated ~300 hour mark), but I am concerned about a certain lack of detail in some songs (even after eq'ing) which my old apple iem's (the pre-addiem ones) have no problems with. I'm really hoping this clears up, but at 80 hours so far I am starting to get concerned.
A perfect example of this missing detail is on the slayer song aggressive perfector... there is a second guitar playing in the intro that is quite clear with my apple iem's, but can only be heard very faintly in the first few bars then disappears on my ie8's.
I'm wondering if a matched amp such as the icon mobile would fix this, if it just needs more burn in, or if the ie8's genuinely can't show details a £30 pair of iem's can. Would appreciate someone more knowledgeable's input on this seeing as I have next to no experience with high end iem's, having only owned said apple iem's and cx300's previously.
edit: decided to create a 4 second crop of the song I was just talking about to illustrate what I'm saying, with my ie8's the second guitar mirroring the first at a higher pitch is just about audible in the first half of the clip but isn't audible at all in the second half. Perhaps someone else with ie8's could let me know if they get the same result as me or if not what their setup is. BTW my source is an iphone 3gs, though have also tested this through my pc using a creative audigy 2.
