I do. In my ears actually
cool... what do you think?

I posted my impressions about them some pages back, specifically comparing them with the regular ZS3(slater mod). I'll search for it and link it.cool... what do you think?

ZST lineage in comparison.
Red = Zsn Pro
Blue = Zsn
Black = Zst
(All run back to back on same date)
No, I made that myself by modding an EDR1 from the fixed cable to mmcx.
It’s the same idea as the mmcx conversions some people have done to the Sony MH755, KZ ED9, and @CoiL’s ATE from back in the day.
I referred to it as the EDR1 Pro because I was poking fun at how everything has the word “Pro” after it now.
KZ has nothing that comes stock with mmcx that I know of.
Sorry if I confused anyone!
Uuuuh i really wanna do that with my edr1 as well, i hate EDR1's cable but i even love the EDR1 itself.
How did you do that?
I find the TRN cables crap. Stock KZ cables are light years better. I dont know why people change their cables. KZ cares about the quality of their products.Few weeks ago I used the black-white TRN 8 Core cable and didn't like how it changes the sound.
The C10 do sound slightly boring but they make it up by sounding really amazing. Thanks for your ZSN Pro comment.Just got my ZSN Pro. Boys, i do not own the ZSN but i prefer the ZSN Pro to the C10.. i'm not after 100hrs on the C10, but the ZSN Pro are Fresh!

That is very detailed.Very carefully haha
Yeah, those sticky KZ ‘gut’ cables were the worst, weren’t they? If you breathed on them they tangled.
So how comfortable are you with micro level stuff? It is not a mod for the faint of heart.
On a difficulty scale from 1-10, I’d rate this a 7.5.
There’s a number of challenges you have to overcome:
1. Seeing what your doing (ie magnification)
2. Getting the shells apart without destroying them
3. Modifying the shells for the mmcx jacks
4. Soldering everything without botching anything up
For doing most of the work, clearly seeing what you’re doing is a challenge (especially soldering).
I don’t own a soldering microscope (I wish I did), as it would have made the job so much easier (at least the soldering).
For seeing what I was doing I had to use a combination of reading glasses, jeweler’s optivisors, and a magnifying glass (the kind attached to soldering ‘helping hands’.
Getting the shells apart was a big challenge. 1 shell did pop apart with nothing but my hands exerting moderate force. The rest (80%) were put together so tight, I had to use 2 pairs of channel lock pliers to grip each half of the shells. And even then extreme force was required to just barely loosen them at the seam. Then I spent about 5 minutes of careful prying and leveraging with an iSeasamo.
It’s also difficult to prevent cosmetic damage to the shells. I used rubber tubing to protect the shells from getting marred by the grip of the pliers, but even with the tubing I still chewed up the shells in a few spots trying to pry them apart. At least the eartip covers up the plier marks I made on the nozzle.
Heat did not help loosen the shells either; they’re mechanically pressed together (not glued).
As far as modifying the shells for the jacks, that’s fairly straightforward. You just enlarge the hole that the stock wire goes though. I tried 2 different types of mmcx jacks and they didn’t work at all. I ended up using a threaded jack which did work, but it’s some sort of ghetto mmcx jack that only works with a small # of mmcx cables. I ordered a 4th style of mmcx jack that I am hoping might work better, but it hasn’t arrived yet so I have no clue if it will work or not.
The next hurdle is soldering. You have to have a fairly good soldering iron (or soldering station), with a really small tip like for SMD work. Otherwise you may as well not bother. A cheap 30W eBay/Radio Shack pencil soldering iron isn’t going to cut it. Something like a Hakko FX-888D is fine.
Soldering the wires to the mmcx terminals is extremely difficult, as you can botch up the jack or even solder the terminals together. You can’t imagine how small these wires and jacks are. Imagine gluing a 1” piece of dental floss to the tip of a pencil. That’s how small this stuff is!
I have the utmost respect for our friends in China that assemble these multi driver IEMs every single day. I know we all get irritated when there’s a little QC defect with our $25 budget IEMs, but I can only imagine perfectly soldering and assembling 10 drivers, jacks, and crossovers into an IEM. Making sure everything is wired in phase, soldered perfectly, mounted properly, sealed up, etc.
Anyways, you also have to keep the wire pieces as short as possible, or else everything won’t fit back into the shell. My wires were about 0.75” total, and you have to hold everything in place while soldering with helping hands and/or tweezers.
There’s no room for error, and you have to have very steady hands. If your hands shake worse than a meth addict, you’re gonna have a difficult time.
Of course you also have to be careful not to overheat the drivers (which will damage or destroy them). That’s why you need a really good soldering iron. You have to be done soldering in a fraction of a second (like 0.5 second max).
You have to watch your wire phase to make sure you solder everything properly. On the mmcx jack, the center pin is + and the outer terminal is -. For the driver, it varies between drivers. Most manufacturers put a red mark on or near the + terminal, or you can usually go by the colors of the stock wires. You can also use a multimeter and check the wires in the stock 3.5mm cable to figure out what wire is what.
Before you close to the shells you’ll want to test the mmcx jacks of course. I used a multimeter to check for continuity, proper +/- connectivity, and electrical shorts. If all that is good, you’re almost home free. I would not connect a mmcx cable until after you close the shells.
Putting it back together is fairly straightforward. You carefully tuck all the excess wire in with tweezers and close up the shells. I gently and evenly pressed the 2 halves of the shells back together using a small mini vice made for working on watches and jewelry.
The whole process took me about 2.5 hours, but a lot of that was trial and error and solving problems by winging it as I went along.
Just like anything, practice makes perfect and as I do it more often I’ll get better and faster. My goal was really to start practicing on cheap EDRs before I attempted progressively more expensive or harder IEMs (like MH755, ED9, Moondrop Crescent, building my own IEMs with Knowles BAs, etc).
Whew! That’s about all I can think of. I hope that’s helpful!
I feel the same thing about the C10.The C10 do sound slightly boring but they make it up by sounding really amazing. Thanks for your ZSN Pro comment.
Presenting the KZ EDR1 Pro:
i am truly envious of your skills--the foregoing epitomizes the difference between someone who can actually build something and someone like myself, who struggles to change batteries on the tv remote. on a certain level, it seems like overkill for a $3 iem (like putting a mercedes grill on an old vw), but that's probably just my jealousy.Very carefully haha
