My RE00 arrived yesterday and I gave them a good listen for about an hour. I would say they are pleasant to listen to but hardly worth the wait. For $35 I didn't expect much but with so many glowing reviews on the lineage, I thought they may something special, they are not.
Cons: Really hard to physically tell left unit from right, bass is light, weak display of channel separation.
Pros: Laid back and smooth with good overall sound.
I especially liked them...
