I have the same exact setup for a year now (HE-500 + nfb 11.32) and I still LOVE this headphone, but I listen to mostly high bpm electronic music (J-core, dum and bass). I can also say to my ears, rock and classical sounds very good on them too... but I haven't ever heard a good recording that sounds bad to me on these... I don't listen to k pop so I can't speak for you there. Still a joy to listen to it every time, and I've put over 1500 hours on it just on music, not including gaming, movies, etc. Are you using velour pads? they make it brighter than pleather. Btw I'm a believer in burn in for dynamic headphones, but the he-500 didn't ever seen to burn in for me. I will never sell mine either as person above me said haha. Hope you find a way to enjoy this wonderful headphone.
Idk if you like electronic music at all, but I will try since you asked for songs. A lot of J-core is, in my opinion, mastered and produced very well for electronic music, and some tracks have FLAC bitrates of 1200+ and really show the difference in detail retrieval between higher end headphones and something like an ATH-M50.
idk I tried
