I’ve had the PX7 S2 for approximately 2 years, and acquired the Momentum 4 a couple of months within the past.
Surely the M4 in my books. Motive I modified from PX7 S2 modified into once:
1) the sq.-ish ear cushions in actuality left a shrimp air gap spherical jaw that ruined noise cancelling for one of my ears. Everytime I turned my head the “seal” would spoil which modified into once very distracting having out of doors sound without observe coming out and in.
2) truthfully whereas detail modified into once nice it felt plenty esteem lower frequencies were more lower off.
The create quality of the PX7 modified into once distinctive then again. Looked and felt of route nice.
Things I love in regards to the M4 over PX7 S2 (and my accomplice’s xm5):
1) Sub-bass extension is amazing. Surely has thst sensation of having the ability to “of route feel” the low notes, and no bass bloat. PX7 felt esteem all are trying to amplify bass to yarn for lower-off modified into once neutral elevating more mid-bass and drowning about vocals.
2) Battery life is obviously ridiculously neutral.
3) App has better equaliser.
Consolation-wise I of route feel esteem they’re in regards to the identical. M4 has much less clamping pressure but I would no longer trust them to carry on if I shake my head. I employ earbuds (wf-1000xm5) at fitness heart but I of route feel esteem both can also tumble off if I lay down in a bench with them.
Overally I definitely do no longer be apologetic about facet-grsding to M4. Feels esteem an upgrade to me.
EDIT: could per chance hang to demonstrate I compose no longer employ mic so cannot commentary on call quality; they’re purely for music, media and games for me.
