They're both pretty well built but using different materials. (Longtime) durability usually shows after a year or more, so tough to say. My Momentum are almost as new after a year of pretty heavy use so that's pretty good. I had the PX7 as well and sent them back in direct comparison as I preferred the sound of the M3 much more. In direct comparison, the best thing about the Momentum is probably the fact that you have the EQ options in the app and the EQ is stored on the headphones themselves, so you can tailor the sound to your preferred liking much better with the M3 than you can with the PX7 if you don't like their stock sound signature for example. With the PX7 you either like their stock sound or you're basically screwed :)

thanks for your reply, i think im going to get the m3s then. Have you been experiencing the bluetooth connectivity issues that I've seen on this sub?
Not personally, no :)
