The only things that could be better on the Dolphins are the soundstage, and slightly reducing the peaks in the mids. They look and sound fantastic, especially for $99. They have pretty satisfying bass for a mid/high boosted headphone as well.
The Drama is sexier, but reminds me of a clearer Beats set, focusing on bass.
I don't know how to put it, but it's like the bass, mids and highs are all forward/prominent, so they all even out to be overall balanced. It's a complete in-your-face experience, great especially for blood-pumping rock and metal music.
