iems upgrade

Hello! I've been using my Truthear x Crinacle Zero Red iems as my primary pair for almost two years now. Overall, they satisfy me in every aspect, but I'm feeling the urge to upgrade. My goal is to find a new pair of iems that give exceptional and very good electric guitar sound — since I play eguitar and value strong, clear mids (or whatever is needed for the best eguitar sound) — and also excel for listening to genres like metal, metalcore, nu metal, black metal and so on.

I'm good with a budget of up to $200, though I could stretch it to $220 if really needed, not more. Currently, I'm looking at the Tangzu Wu Heyday, which I understand are well-balanced across all frequencies, but I'm curious if there are better options specifically for electric guitar. There's also the Kiwi Ears Quintet, reputed to be very great for eguitar, but.... maybe something else out there that will be even better?

I'd really appreciate any opinions, suggestions, or recommendations. Thanks in advance! :)
