Just read your review on the xtc and saw you talking ab the 2.5 at the end so here are my thoughts on it. I have the xtc 2.5 and I believe I’m also the first person to own it and lemme tell you in just a quick sentence, it is head and shoulders better in every way than every headphone I’ve PERSONALLY used; and I’ve used the hd600 and 650, Beyerdynamic dt 900 prox, ether cx, nectar ambrosia, audeze maxwell, and ksc75x, and mannnn these are easily the most comfy and best fitting headphones by far!! And literally ever. Single. Genre. Sounds absolutely sublime! The dynamics and punch and slam make anything you listen to, whether it be music, games, movies, etc., so damn immersive, and not to mention the fact that these are the most natural sounding headphones too! And with the amphitheater cuts in the headphone and the fractal mesh these sound HUGEEE like as if you were in a massive opera house, but that doesn’t hurt the imaging, instrument separation, or detail of the headphone. Everything is where the engineer intended it to be and nothing every gets in the way of each other; so these definitely would be amazing headphones for mixing and engineering because it definitely reveals any flaws ur music may or may not have, but these reveal them to you in a way that is never fatiguing, no, instead these are genuinely super addicting headphones with their sound, especially bass and sub bass oouuu that’s fantastic lemme tell ya! Real hard hitting even the sub bass but never intrudes on the other frequencies, it just perfectly compliments them! These definitely deserve the name xtc(ecstasy) bc when you’re wearing them that’s all you feel!! And if you can save up the money for them I highly highly recommend getting them!
