Its been out for just a few months... not sure what it is "known" for. The dilemma I had was similar to this in that I had an Apple credit to use and they had the P7's, Momentums, and BO H6's.
It all comes down to personl taste, but based on the poster's options, I would say the P7's.
Is it's soundstage better then its competition?
How'd you get the Apple credit? Doesn't apple have a few more options: like the M500 and MOE.
