I'm about fed up with the feel of the ES7 .. for some reason my ears just fight the pressure and the sides of my head just stay tense the whole time I wear them. I'm considering other supraaurals that might be more comfortable, especially the HD238, but I expect I'll be as annoyed with other supraaurals as I am with the ES7. I'd like to find a circumaural that's maybe not exactly portable, but at least 'transportable,' and would be at least competitive with the ES7 for SQ if not an upgrade. The DJ-type black plastic phones (m50, srh440/840, etc) are an obvious but bulky option. So are the Denon D1001, but I sometimes see them listed as on-ear, and other times as circumaural. Which is it? And, other suggestions? i have a portable amp (PPAS). current source is a 1st gen Zune. I listen to all varieties of music, so an 'all-rounder' is preferred. under $300.
