Hey MH
I totally agree about the new Beats Studio sounding great. Honestly, it's like a 1000% improvement over the old Studio, it's nothing short of a miracle turn around. I wouldn't mind listening to them as a portable can now (on the plane or subway/buses). It paired well with the X3. My only complaint about it is that it can't be used in passive mode and so the battery must always be charged and NC on. The NC hiss was acceptable for me though. I thought the old studios represented about $10 in sound, I think the new one's represent $200. So that's like a 2000% increase in my mind.
I tried auditioning the H6 and P7 using my X3 at the Apple Store, went there again today. (3rd time this week), and honestly I think their system or the loud enviornment is interfering with my ability to see their qualities. I of course checked for a good seal fit too. The Beats Studios sounded better with multiple songs from multiple genres (all lossless of course). Which I'm pretty sure isn't right. right? My guess is that they plug the headphones into something really bad quality over at the Apple Store, before the line comes back out again to plug into the headphones. Not sure what's hiding under that desk, but it's ont a direct line from headphone to my X3.
The impression I got about the P7 was that the treble was too hot, the mids too thin and the bass, although well extended, sounded a bit flabby and loose. I did notice however that they were the most resolving of all the headphones there (but not by much). Overall I preferred the Studios over all the phones at the Apple Store.
I might go tomorrow and purchase them both and test them out at home for 14 days and return one of them, or maybe even keep both if they're worthy. I didn't want to do this because I always feel bad about returning headphones, but it's getting to that point where I'm kind of frustrated...
