Newer KZ IEM specially the DD releases doesn't have that metallic treble anymore and boxy sound. So far out of the newer KZs I have, EDA Trio, CRA+, EDX Ultra, ESX..ESX is the safest tuned and has the most likeable signature, the bass may be too much in some tracks, but you just need a widebore tips like Kbear07 to counter that. Imho, all KZ iem should include a tips that is somehow similar to Kbear07 or just straight up widebore tips, the KZ starline/stock tips degrades the overall sound quality in my experience.
Removing the mesh from the iem housing of the ESX improves the clarity.
It is glued, so the trial is possible without any damage.

Isn't that filter used for reducing the upper midrange and lower treble? Most likely removing that will increase the pinna gain region making the sound somehow clear but with the caveat of making the vocals shouty?..hows the vocals when you remove it?

Man I just tried your mod and measured them with and without the filter, bruh it sounds more amazing now..Clearer, bass isn't overpowering anymore....what have you just suggested, this is just too good.

My ears are golden 😂😂😂
The niche thing here is even if the pinna gain is increased by about 4 dB, the vocals isn't shouty whatsoever, its just cleaner and more transparent than stock..man my ears are very happi now.

WTH!?

I just received the KZ Z3 TWS, which clearly KZ states are aptX HD compatible, that's the reason I bought them, and this is what happens:

I have a KZ BT 5.0 cable and it automatically switches to aptX HD, so it's not my smartphone, which has a SD 865 and supports everything.

Are you guys using the stock tips with ESX with or without mesh?
I'm using mine with Kbear07, stock tips kinda degrade the sound imho. Sounds good even with filter or non.

Edit. I misread the specs of the chip so this post can be deleted.

Well I have checked for you, but the chipset used in Z3 (QCC3040) doesn't support AptX HD. Which can be seen here: https://www.qualcomm.com/products/application/audio/qcc30xx-series
