Solderdude, did you hear any difference with your new(?) pair? After a month and half's pretty much constant use it feels like the highs have gotten more prominent, to the point that they start to hurt my ears before I get the rest of the spectrum to the enjoyable levels. At the same time the bass has settled down a bit: they started from about same level as my slightly modded JVC HA-400 and now I can't really call it emphasized anymore. The change was pretty rapid too. Up until this week they sounded good.
Shame, i really liked how they sounded as new. Now my ears just can't stand them.
