I prefer both the Utopia and Ether Flow over the Elear for rock and metal. Depends on your tastes though, obviously. For Metal, I tend to prefer the really elaborate, progressive stuff (Necrophagist, Spawn of Posession, Psycroptic, Nevermore, BTBAM, Protest the Hero, etc). All that stuff really benefits from a speedy attack and decay, solid impact, a neutral tonal balance, and gobs of clarity. For that, I would take the Utopia or Ether Flow (along with the HE-6 or the Abyss). But different metal genres have different requirements - old thrash can be kinda thin and black metal can be kinda bright, so both benefit from a slightly darker headphone like the Elear. Some of the sludge, stoner and doom stuff just sounds better with a chunky presentation and could be good with the Elear as well - though I think the pre-fazor LCD-2.2 is still the best for that stuff (like The Sword, Mastadon, etc).
