Very good review. An enjoyable read through. I especially like your impressions of the HTX7s, I've heard some very good things about them but reviews are few and far between.
Perhaps you may be interested in reviewing Audio-Technica's SQ5s. You can get them on sale for $60 at Audiocubes for the time being. I imagine they're quite similar to the JVC Black Series, but I'm still curious how they compare.
Thanks. I was surprised by how capable the Panasonics were for a mainstream phone. The JVC HA-S700 certainly gets some undue praise here in comparison to those.
Audio-Technica makes too many headphones! I'll be hearing the ATH-EM7 pretty soon courtesy of slntdth93 but we'll see what's what afterwards.
Is the 650 collapsible? I thought it was just flat folding a-la Senn HD228
