As I feared, they are quite sibilant, according to the article.
Personally I'm not suprised if I'd like XB900 more than XB1000. The description of XB1000 even if they costed say $150 wouldn't make me get them, XB900 on the other hand seems more along my personal tastes. Well both XB600 and XB900 seems to pack lots of punchy bass based on the shape of FR graph, at least it's safe to assume both will feature more punchy bass than XB700 just by looking at the graph. Actually I think XB900 looks like it would sound punchier/snappier than XB600 in the bass. Why? Because it rolls off very slightly in the very deep bass range versus XB600, trust me this isn't a bad thing but a good thing if you like punchy, snappier bass than lowbass soft rumbling bass ala XB700. From experience I can say "hill-shaped" bass response with a peak around the midbass region, especially when the peak is centered around 80~100Hz or so gives you the ideal punchy bass that should roll off down deep slightly. Very low frequencies demand more power and low frequencies are slower (this has to due with the wavelength being longer) and if you cut out some at the very deep range it helps providing you more of the punchy/snappy higher bass frequencies as there's more power to be focused there. It's not ONLY down to the shape of the bass curve but it's also down to the driver's ability/quality itself as can be seen from for example the typical 30Hz squarewave measurements but the shape of the bass curve do also contribute and if you take all known punchy bass headphones they almost every1 share this "hill-shaped" rather than flat extending down to like 20Hz bass curve.
Good example of "punchy bass" measurement:
Hill-shaped bass curve + 30Hz squarewave has this very "curvy" pointy shape. PRO900 are among the "punchier" headphones out there, it's not the tightest but fairly "tight"/fast bass, the vertical length determines this.
For example Fidelio L1 has suprisingly punchy & snappy measuring bass, just look at that beautiful 30Hz squarewave:
