The p7 looks too chunky and rectangular for my tastes regardless of how they sound. Also I imagine the leather wouldn't wear too well with outdoor exposure especially in cold climates.
I must say the 7520 is instruging too though.. It doesn't strike me as a portable more a closed monitoring can but I guess you could use it that way... Be better if it didn't have sony written on it though. It bugs me about my dt1350 too but at least you can choose to remove the outer white logo plate and make it more stealth.
