I agree with everything else except for the Momentum's ranking higher in "sound quality/build quality" than the PSB M4U2's . Moreover, I disagree that the Momentum's rank equally with the PSB's regarding "treble", "bass", and "imaging." My listening experience with the Momentum's wasn't so good. I perceived that the bass bled into the mids and made the sound a bit muddy. Treble detail wasn't so spectacular either; there was a slight liveliness to the treble but in the end, the treble seemed a bit recessed to me. The imaging of the Momentum's is almost on par with the PSB's, but the PSB's image better due to it's better treble response and due to the fact that the bass does not bleed into the mids as much. I also have to disagree that the bass ranks higher with the Momentum's than the PSB's. The quality of bass for the PSB's is way better than the Momentum's in that it sounds fuller and more controlled. The Momentum's just boast more quantity in the bass department, but it sounds very dull/bloated to me. The build quality of the PSB's although it is mostly plastic feels way sturdier than the Momentum's when I am holding it in my hands. Plus, the cable on the Momentum's is way to thin, while the cable on the PSB's are thicker and better built.
I have to say the imaging on the PSB's is on par with the P7's but does not seem so when comparing them because the P7's have an accentuated treble response and just a different representation and sound signature (Forward; V-Shaped) than the PSB's (Mid-Centric). The details in the music are "all there" when listening to the PSB's, but you need to really listen closely to notice. The soundstage of the PSB's is way better than the Momentum's and better than the P7's in my opinion. The width/depth of the soundstage and balance of the sound frequencies give you a beautiful sense of space when listening to the PSB's. The sound is very natural and life-like; this is perfect for movies and orchestral music. It's true that the P7's have better instrumental separation, deeper/punchier bass, and a more lively treble response than the PSB's; but all of that sounds very, very unnatural to me compared to the PSB's. I think the P7's are great for rock, metal, electronic, rap, and jazz. But the PSB's are better for Vocals, watching movies (because they sound more "real"), and Classical/Orchestral/Acoustic/Instrumental music. In the end I prefer the PSB's even though I listen to mainly rock/metal because I can't get over how colored and artificial the P7's sound. But you got to admit, the PSB's are ugly! And the P7's are gorgeous! :)
