Absolutely. M3 > px7 except in battery life
Err, nope.
I returned the M3 and will be keeping the PX7 Carbon Edition
M3s have poor ANC, very poor battery life, and for me had a poor fit and slid down when I bent my head down.
Also the earcups are only suitable for small or medium size ears.
The earpads are nice, genuine leather.
Build is nice but the buttons etc. are better on the B&W I think.
The metal hinge sliders aren't a great design I think and a finger/skin trap - I cut my skin taking them off in one hand - got caught in the hinge.
I found the bass fatiguing and not rich and warm like the PX7
Perhaps some will find the PX7 bass bloated - I would describe it as blooming, rich, enveloping.
It doesn't take away from detail and separation, but with electronic and bassy music can be very rich and present.
Not so with the M3 I found.
M3 did have a more consistent sound though and no recessed vocal issues.
PX7 space grey I did notice recessed vocals sometimes, but other times rock sounded great.
Generally they need some volume to sound good I think.
I didn't notice any difference between the carbons and the space greys when trying one track, but will listen to the carbons more.
As for physical differences, the carbons use a softer black nylon material. This actually looks cheaper than the grey material on the space greys. But the grey material won't age as well I think. Also the carbons look smarter. I quite like the chamfered shiny edge on the earcup metal plates too.
I still wish the earcups were larger.
Would be awesome if they sold larger leather earpads that come out a bit or come in less. May look less elegant but would be good for long ears like mine
The Aonic 50 review very poorly on Amazon - loads of issues it seems.
They also seem heavy and less travel friendly.
Poorer ANC, but importantly they have the smallest earcups of the lot.
So only for midget ears it seems.
Not tried them but pointless for me as they have less ear space than the M3s apparently, which have less the PX7
The PX7 are only just okay in ear space for me, and still not ideal.
I believe the Bose QC35 have even more space, no idea about the N700. But Bose lack loads of features, look cheaply made (at least the QCs) and sound thin and crap in my experience.
PX7 FTW
