I tried the Tributes for an extended period first but aside from their lousy QC, not impressed. Got the Trumpets next and never looked back. I did use a different tip, from an old JVC that works with the Trumpets (a bit softer than the Monster tips), but to me, one of the strengths of the Trumpet is the fact that the highs are never harsh. I did give them 40-50 hours of burn in since they are micro DDs, but now, I put them to the test with my most sibilant tracks and they pass with flying colors. To me, they are more balanced than the Tributes as well. They have a neutral, crisp sound. No, they are not warm like the Tributes, but that's a plus to me since they are a bit more analytic but never dull or drained of energy.
Vanilla or chocolate I guess. Could be ear shape or something regarding you hearing them harsh and others not. Also, I wear them over the ear and I believe it is a better fit and also eliminates cable noise or the need for a shirt clip. Yes, the iPhone thing is higher up, but it doesn't bother me.
