The E3C's are the same way. You tell yourself that the 149 for the awesome midrange is worth it... but then you play a song with good in your face treble, and you get the all-too-familiar grainy sound of the rolloff. You know to be fair, those were made in the time when people were just impressed with isolation and thats it. The build quality is kind of bleh for such a thick cable. I still rock out with my SC3L (rerelease of the E3C) from time to time, since it's good for crunchy guitar, but other than that, the ER-6's are king of the hill until I can figure out how to get ER-4's in my life haha.
I cannot in good faith recommend Monster anything. The Turbines are good, not great. You have to spend bit more to get their decent IEM and I don't like that, I think any manufacturer should be able to make the best headphone they can given the money, and 100 dollars buys a LOT these days.
If it were me, knowing what I know now, I'd have to just buy a set of Etymotic HF5. If you listen to Radiohead and you want to hear everything, Etymotic has never disappointed anybody who listened to serious music. I'm listening to Radiohead right now on my ER6's just to be sure of this recommendation. If you don't like them, return them back to Amazon, no questions asked and swap 'em out. I've tried a lot of other IEM manufacturers over the years but somehow I've grown accustomed to listening to "quiet" music very clearly and with all the detail I was meant to hear. Radiohead is one of those artists that I frequently visit with my Ety's these days.
You can get them in that badass ruby color! Etymotic is COOL now!
