Dude. These things rock. They play everything well just like an accurate neutral earphone would. If this is close to the ER4, I wouldn't mind splurging for those in due time.
Not as good of a midrange as the Shure E3C's I had, but those had really bad rolled off treble and the fit without foams was a little off. I had to resort to tri flanges on those bad boys. The bass doesn't go as deep as my Grados that I love so much, but hey, it's an IEM.
Cable is absolutely one of the worse ones out there though haha. The isolation is the best. I'll take that!
Anybody else have/had these?
