Sure sounds like a description of the RE-400's.
Now I'm leaning towards the Rock-It Sounds R-50 and the Hifiman RE-400. Custom tips aren't as appealing to me anymore after I realized regular tips are actually pretty comfortable, I just had the wrong size for my current IEM's. So that's why I might not get the Etymotic HF2. According to joker's IEM review, both the R-50 and RE-400 are superior in sound, so it's really just down to these two I guess.
