Initial impressions of the Eterna Rev.2 are positive. Rich, full sound. A bit on the warm side, but not too bad.
Excellent for hard rock. You can pick apart a drummer's performance as the heavy vocals boom in the foreground. Drums do not overpower as there is so freakin' much going on that everything just booms into your skull.. But not in a bad way
Not great for soft rock. Drums appear to overpower softer guitar melodies and vocal performances. These are IEMs made for NOISE. The more going on in the song, the better. Perhaps that's what ClieOS meant by "fun"?
Electronic is surprisingly detailed, surpassing the notoriously cold RE2s despite having considerable more bass (which I was worried would negatively affect detail). When you get these IEMs, this is what I want you to do: Pick a song that has your favourite beat lead-up. As the beat builds, prepare yourself... When the beat finally drops, you will wonder how you ever appreciated the song before listening to it with a lesser IEM.
One thing I've noticed.. 320kbps is a necessity for my tracks now. I couldn't hear the difference between 192 and 320 with my RE2s, and boy, I can hear it now.
More to come after a proper burn-in!
