Does this review of the re-600 match people's impressions?

Not mine, at all really.  Bright?  No.  Bass light?  No.  Makes bad recordings less bad?  Yes.  I thought they were slightly veiled.  I brought my own tips to audition them.  Sound like an ER4S?  Not really.  I get what he means though as they are both balanced sigs but they have two distinct flavors.  I agree the RE600 is not analytical, the ER4S is more so.

We're going to start enforcing topicality, too many threads wandering lately....
