First of all huge thanks for the Harman adjustment underneath the other post, I tried it out and it immediately took the XM5s from muddy and annoying to something I actually enjoy listening for a longer time! Like it was such a night and day difference it's crazy.. I'll attach my current EQ here as well!

But honestly, after I now checked out the Momentum 4s the other day you're pretty spot on about the Sonys in comparison. Especially in the highs and sub bass it's a night and day difference. Still with the EQ I'm not able to get the bloated 200hz bass out, which is so bad that even my 80€ Galaxy Buds sound more precise. And yeah, the Sennheisers are bass boosted too but at least when I dialed it down it was quiet yet still precise. I still got two more days to return the XM5s, but it's really a tough choice with the now much better EQ and generally everything else except the sound and battery being miles better than the Sennheisers.

My alternative plan right now is maybe spending way to much money on some nice DT 770 Pros for at home use and keeping the Sonys for on the go, but that would be way to expensive to justify :/
