Moondrop Blessing2 + Spinfit W1 tips + balanced modular cable + Fiio BTR3K
This setup is comfortable and secure in my ears all day long & sounds great on the 2.5mm balanced port of the btr3k. I usually keep in it LDAC or APTX-Hd and its basically indistinguishable from lossless. Plenty of power and an overall pleasing sound signature thanks for the AKM dac.
Nearly same boat: 7hz timeless, balanced cable from Amazon, spinfit cp155, through a qudelix 5k. Def gonna be my endgame.
