There seems to be a lot of interest on the Sennheiser Momentum thread currently from some of the same people on this one. And the Senns come in one of the only colors not offered by V-Moda: Brown with real leather pads. I have to say, the headphones case, metal headband and removable cable look awfully familiar.
My request that V-Moda offer pads in real leather, seconded by others, might prove pertinent right about now.
The sound comparison is the mystery, though.
We know that the Momentum uses a variation of the drivers used for the HD-25, so we're pretty sure about how they're likely to sound (though apparently they're tuned for a bit more bass than previous models). We don't know how the M-100s are going to sound except anecdotally.
I've heard the Amperiors and thought they were overpriced and not nearly as well constructed as the M-80s and M-100s. They were balanced (if you're not a bass addict) and certainly listenable but not stellar.
I'm still considering whether I'd pay $185 extra for better construction, that delicious appearance, superior comfort and a circumaural seal and fit.
One thing seems likely: Visually, the brown, silver and updated retro styling make the Momentum generation-nonspecific in ways in which the M-100 might not be. People who bemoan the blackness of their headphones ensemble but aren't ready for the conspicuousness of white might see the brown leather Momentum as their trichromatic sweet spot.
