One thing comes to mind is replace the default filter with Tanchjim Filter.
It works to smoothen DQ6 peaky treble. Not sure whether it gonna work here.
Well, i have pulled out the default filter of my Moondrop Aria to look for that lower mids and bass per AmericanSpirit suggestion.
The bass somewhat increased, feels like it push more air, in the same time it cause the feels of it become abit more "loose"?
Not a bad thing, but yeah, it causes some changes which goes closer to my preferred sound.
But then Edric points out that he wants to lower the treble, i remember Riku filter suggestion and replied with "
just put tanchjim filter on it".
And i was like, I have Aria and i have tanchjim filter from Tanya, why not just try it?
I did it, its my first filter install. Not quite centered and some got pushed inside (get a bit tilted) as i reinstall the eartips.
But umm, i just trying it out for 10 minute or so... its kinda good.
It still have bigger bass of the no-filter, but it have more "thump" and maybe bit more rumble(?) instead of the loose air feels that the no-filter give.
I'll try it out for the entire day to feel it out.
Sound alteration aside, i simply want to add a bit more protection to aria, the gaping hole of no-filter that might collect wax , lint or water is a bit worrying for daily driver.

If you dare to mod things a bit, KZ AZ09 Pro is pretty decent TWS connector.
You need to cut the C lip, so you could insert it to Moondrop recessed 2pin.
