Jeez does that look fantastic.
Definitely looking forward to your review, brother!

I am legit hoping to eventually get a pair or if luck has it win one from HBB. Either way. One day for sure will get it. Looking forward to your review brother.

Right on, loving mine. Don’t find it too bassy at all, just right
Gonna be a hard one to dethrone, personally.

The punch really nailed it with being in precisely the right price range IMO

Hello everyone!
Since because of sanctions I can not accept payment with PayPal in Russia, I need to open a company in another country, this I will do because people are more convenient to pay through PayPal.
While many people are not familiar with cryptocurrency, it is just gaining popularity.
At the moment on my site you can pay in cryptocurrency with Visa/MasterCard using Cryptomus.
This is the ZE311B Demo, there is no review of this model yet.
I am now starting to customize the ZE101B.
In the future is planned:
Send ZE311B for review.(Once PayPal is working).
I am now starting to configure ZE101B (10BA + 11mm BCD).
Next configuration will be ZE102D (10BA + 2DD 10mm)
I will try to customize and squeeze the most out of the high-end drivers that are on the market in the ZE101B/ZE102D models.
And also make a ZE101B/ZE102D version with DSP.
About the DSP - this is a difficult implementation as I have no knowledge in PCB board design. I am currently looking into this, I may have to contact engineers who can help design this portable version of the DSP.
It is now possible to build a stationary DSP, what is left is to make an amplifier for the IEM.
What is your opinion? Is a portable DSP mandatory or can a stationary DSP be organized?
Of course I understand that people want to buy a set without DSP (ideally tuned) but unfortunately nothing is perfect and there is an opinion about it:
- Capacitors used in all IEMs cannot clearly separate the drivers by frequencies, or rather the cutoff is insufficient, even when using 220uf capacitor.
(Application of 220uf capacitor for mid/high frequency cutoff)
(Applying a slice with DSP)
-
“Equalization of each driver” - also all IEMs use filters to smooth frequencies with different impedance or in rare cases acoustic design is used (rare application and not effective)
-
With the application of a full-fledged DSP in which the equalization of each driver and frequency cutoff will be implemented, this IEM will already be close to an ideal solution.
As far as I know @hawaiibadboy worked in auto sound and he knows how it works.
Also thinking about the name of the following IEMs.
ZE101B/ZE102D technical model names
How about we have a vote for a new name for these models?
What do you think?

I love your naming system. Like Canpur is basically describes the driver count and driver type (main driver of set as last letter) super easy and professional. You guys can vote away. I like what you do now.
Like the xMems, its a quality vs convenience thing/balance. I think you should work on both in parallel and drop the non DSP gears to build capital to help fund the costs you put into a DSP set. I Love the Soranik with the amp it needs with no issue. There is a market there.

I agree with all of this @Anatolyi_ZE ; technical model numbers make sense to me, and if you want you could give a “nickname” to a given model if inspiration strikes along with the descriptive model designation. I also agree on the DSP; your end goal should probably be an integrated system a la Brise’s Fugaku or IEMs with USB-C cables & DACs in one package, but there will always be a market and a place for more traditional sets to help support the bulk of your buisness as you grow it.

I think the naming convention, as is, works really well. You can do nicknames if you want but the standard IEM being no frills really works.
Excited to see the new stuff!

Sheesh, are you putting in work, my dude. Very cool stuff! Thanks for sharing the journey with us all.

Perhaps you can “cheat” by pairing it up with something like the Fiio JA11 dongle which has built in PEQ that you can set and have in the memory of the dongle.

Yes, the plan is to create a DSP with presets.
There is not and cannot be any trick in it!
Because I am always transparent and show what I do.

Wow! 5 tubes? Is one for pressure relief maybe? Cool to see the prosess for sure!!

I believe he is aiming for multichannel dsp/dac solution to tailor FR for each/some drivers.
just curious is there any IC that can do it with enough power, quality and low consumption and be placed in the iem. like in TWS but multichannel instead of stereo.
I think for the first iteration desktop is totally ok to see how it goes. Then maybe some midsize usb-c powered (ie ~size of a phone/powerbank), then a dongle. It really depends on parts used, power requiremends, connectors used, etc.
my “portable” ze51b 
added some gain in fiio app. eats ~1% of acc per minute. excellent sound and comfort. 4km morning walk to office - 45 minutes of pure fun and energy. sadly sometimes it’s near or below zero outside and I don’t want to risk my precious ZEs.

Oooh, love the color scheme!! Purple and Gold was my request on mine as a lifelong Lakers fan. This appeals to me in ways you can’t even imagine.
