New Head-Fier
You can remove a hex filter of stock Moondrop Aria 2021 to make it close to KBEar Lark's bright-neutral signature, and it is a considerable upgrade. Aria on sale could go as low as $69 USD. HZ Sound Heart Mirror is also a bright neutral tuned single DD, but Aria's sound is more natural.
I have both KBEar Lark 4K(old version), and new Lark, Robin, pretty much all new CCA / KZ / Moondrop IEMs as well.
TFZ Live 3 < nah too V-shape, you won't like it.
ZAX< not your liking sound, it's still U-shape with bits of spikes compared to Lark
CCA C10 Pro < too V-shaped
TFZ Live 1< basically all TFZ are V-tuned
Kbear KB04<< KB04 is actually a discontinued product, replaced by Robin (4BA+1), it's warm-neutral-ish sounding with V-accents, but technicalities aren't far from Lark, only slight upgrades.
For sub $50, with a bright neutral approach close to Lark with a significant sound enhancement, is GeekWold GK10, it has a slightly higher mid-bass floor compared to Lark, but it can be adjusted by ear-tips with the likes of SpinFit CP360.
Whoa, thanks for making a summary of each of those options
Aria is too big of a jump for now, it's priced about $84 here, used ones with paint chips at $70.
Heart Mirror is also one that I have my eyes on, it's just so hard to find here.
Some reviews bashes the Geek Wold GK10 though, they said some things about incoherence, timbre, bloated bass

Or is it something that the CP360 can solve? I know about how eartips can change some of the sound characteristics but I'm still kind of blown away with that fact
Another one that I have just found out, about in the price range of Aria (at least where I live) is the Fiio FH1s, got opinions on it?
