Was at the apple store at NYC soho yesterday looking to grab a pair of momentums. While listening to them I also tried the b and o h6. That's when one of the associated casually mentioned to "try the p7s, the others are just toys inc the h6". I was hesitant to listen to him cuz I thought he was just trying to sell those instead. I did however, and they absolutely blew me away, never heard such clear midrange in any phones in my life, and the bass presence and clarity was phenomenal. I'm no audiophile who can spend hours analyzing and tinkering with eqs, however you could tell instantly the clarity btwn the p7s and momentums at least which at first sounded great, but after hearing the p7 was almost muddied. It's hard for me to just know but I think I knew from the first time I heard them. Funny thing is I tried to buy them right there, but he didn't even have any in stock, cuz apparently they are that stores best seller.. Now I'm back home in Toronto, and have to see if they have em in stock at the apple store here
I've also got sennheiser hd598, amperiors, tma1, but none come close, though I still love my hd598..
As a previous owner of the Momentums, I'd be skeptical of your initial audition simply because the P7's will sound muddled and congested if fed from the wrong source or fed the wrong songs. The Momentums have a dry, very midrange dominated sound, hence them sounding clearer, especially if the source that the audio was coming from is given a natural "v" equalized sound, or that the song you were listening to had it.
If you hear "Hotel California" over the P7's with a Zune or a stereo feeding it, that "muddied" sound concern flies right out the window. They are so revealing that it's actually a little bad; they're ruining some songs for me by revealing tiny vocal distortions from compression, or floor hiss that I never heard before, but spectrograph readings reveal.
Every time I auditioned a set of headphones at the Apple store and bought them, I'd go home and have a totally different sounding pair because most are driven from iPods, which are the literal definition of hell for music listening. My Harmon Kardon BT's sounded like trash at the Apple store, but I got them for looks, and ended up having a very pleasing sounding headphone once driven from my Zune.
However, if you got to try a pair that you fed from your own PMP/phone, then this would just be a case of varying tastes and at that point, will wish you the best in your hunt for YOUR favorite headphones
