500+ Head-Fier
Have you tried foam tips? With the cheap ali foamies they fit very well when I wore them downI just got my Zhiyin Z5000, totally loving it! Great Bass with decent vocals. Would prefer more details but for its price, its great!
However, I dont like to wear it over my ear. Wearing it straight is a bit uncomfortable, I am unable to wear it deep. Perhaps someone can recommend me a longer ear tip?
You can mess around with eq and turn up the upper frequencies (or tune down the lower end) which helps open up the sound, and can help dig out a little more detail.
