My Xeport 5010-8 continues to impress me. I'm starting to hear grain in the midrange now. Also, there's even more space than before, providing an "out of the head" type of headstage. The positioning of instruments reminds me of my VSonic GR06+Atrio X combo. The treble is not edgy, but has minimal sparkle and good extension (depending on your source). Also, there's the front and back positioning of the 5010-8 and yes, that's how I knew it was 3D, because it goes left, right, front, back and sometimes diagonally. Yeah, I wonder why Xeport would sell this great IEM for a low price? Hmmmmm......
