I demoed a bunch of closed backs and perhaps there is someone that could advise something that I could like according to stuff written below. I have issues with dynamic HPs, as all of them sound muddy to me, but none the less I have not given up on them and I hope to find something that changes the view I have.
Aune SR7000 - no isolation otherwise decent for DD, still veiled for me, Lensys did everything better
Focal Lensys - Best of all DD closed backs I tried. Great acoustic guitar performance. well balanced, albeit slightly too muddy for me
Focal Stellia - I could only poke it with a stick. This has been traumatic experience even compared to 15eur "gamer" headsets. It did some parts well, but female vocals made me rip them off my head and whatever was good was overshadowed.
LCD 2 Closed - Best sounding closed back, fantastic isolation and still comparably spacious. Would require some EQ to bring female vocals alive.
Caldera Closed - No isolation, great, very spacious sounding, but bass is lacking in texture as sacrifice.
Meze Lyric - lacks bass impact but good vocals and quite "detailed"
Meze Lyric II - better bass than 1, more airy and detailed, but vocals a but distant. Plays well on High Dynamic Range mastered files, but really lack-luster on loudness wars affected music files.
