hmm, warm and chill in the $400 range with more bass.
Fidelio x2 hr is very warm smooth and bassy SHP9500 doesn’t have as much bass and is brighter
Meze 99 are warm wide and chill,
Tygr 300r which I just recently auditioned, you can find that review here 🔶 Beyerdynamic TYGR 300 R - #303 by Falenkor
I won’t say 58x is warm it lacks a very bassy presence it does have a nice sub bass to it but it’s very balanced and I would say the HD 558 has that more bassy feature to it instead of the 58x.
Argon mk3 T50RP from Modhouse very warm and very lovely bass
KPH30I super budget friendly very warm
Aeon open x, when it’s on sale, warm V signature with a rolled off treble.
Hmm, just a suggestion though but if your not a fan of such an analytical headphone you may be better off switching to the T1 as it is more laid back with a rounder bass, responds well to tube amps and balanced setups with which I personally use a liquid platinum amp with nos tubes and it really brings out that bass, it is a little brighter than the 1990 though you can change the pads or dampen them with an insert.
