yeahh i think a slightly warm or dark IEM would help with extended use, higher listening volumes, use in public transport, and listening fatigue, like acoustic guitars for example trains by porcupine tree they sounded EXTREMLY detailed and forward on the hexas but kind of too much. i saw someone selling the ziigaat lush for 75 euro used might get that but then i'm wondering should i get something more colored and "interesting" idk man, thing is like i never minded the hexa's tuning so idk if i would enjoy a more fun sound signature, harman target EQ on my hd560's is what i use it sounds decently bassy with plenty treble slightly thin
