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.
My simple setup at the moment is an iPod classic 7th gen and truthear hola. I also have a BTR5. I bought a pair of truth x crin zero red so looking forwards to that.
I prefer overears most the time so don't spend too much on iem.
