Knowledge Zenith (KZ) impressions thread

Hey y'all, long time lurker here. I'll get into a proper intro later but I'm finally breaking silence to ask a modding question.

I know the ZS3 uses a 6mm driver, and thus can accept other 6mm dynamics as drop-in replacements. Is there any reason they wouldn't fit the Knowles SR-32453-000? It appears to be a full-range entry-level balanced armature in a 6.4mm round package with a perfect front cover for accommodating the sound tube.

In theory it could be a very cheap, easy, and interesting way to get started modding.

My ZSR is due to arrive tomorrow - Got the DHL text today Woohoo!!! Looking forward to this and a couple others I need to review. Meanwhile I still haven't written up the Bingle FB60 which deserves way more attention than it is getting. Yes ,it is a V shaped commercial tuning but a $15 bluetooth headset that has not dropped one time in a month of use is quite a rare bird. They certainly got BT implementation right and the cable alone is worth the $15 if looking for a cheap BT earbud to make a mmcx cable out of.

1. That BA driver FR ends @ 8.8kHz, which is "bad" and needs another hi-freq BA upwards from 8.8kHz, thus, making implementation harder. Also crossover might be needed.
2. ZS3 shells take very well even 8mm drivers but thing is - just dropping in another driver doesn`t "make" anything, You need knowledge about nozzle/shells implementation and how to "tune" it all.

For starters, I recommend to start with single DD and maybe then add BA into mix.

They look interesting, so I've just ordered some. Thanks for the heads up.

Looking forward to your ZSR's initial impressions and final review in the future.. :) Sorry guys though, I can't control myself to post some actual photos I've seen somewhere., the shell is a thing of beauty indeed..lol.. pair it with a decent 2-pin cable will make it look more even better..
