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.
Hakugei, and a few no name brands make modular cables. Just be sure to get regular 2 pin and not qdc connector like those on kz sets
