I bet you they are using some Ohm resistors in them plugs which would give you different treble tunings
It looks like the truth.

I'm surprised that no one has done this before.

Now this is a crossover I didn't see coming: Dunu X ZReviews. 2dB sub bass boost anyone?

Jezz, even old guard of the field like Dunu jumps on the collab bandwagon. What a time to be alive (/s). Any news about the unit being retuned?

Simgot has released an interesting IEM which is tunable - not via traditional nozzles or switches - but by different cable plugs!

SIMGOT EN1000

$190 USD

DLC and beryllium plated composite DD

I suspect the "tunable plugs" function as impedance adapters? The FR just seems to change around the upper mids/treble region only (assuming store graph can be trusted).

Maybe bass pot on the cable like JH Audio? (different implementation, of course)

More surprising then that variable volume impedance adaptors (resistors) are not used.
Then a simple volume control adaptor is a variable resistor (typically 1 kOhm). It can work wonders with low-impedance multi-driver IEMs :)

The Z Reviews influence will be upon a new DUNU SA6 rendition, most likely!
Interesting thing on Z tuning, the last one he did (z12?) graphwise it looks like very minor difference compared to the OG but some review definitely hear the difference and some react pretty positively to it.

Not impressed with the "modular cable" on the Letshouer Z12. The 4.4mm plug is already cutting out and adding distortion to the bass. No issues with the 2.5mm plug so far, but I am afraid of swapping connectors lest I ruin the modular system altogether.

I have probably swapped terminations 4 or 5 times, but this has already caused issues. As a comparison, I have swapped connectors on the DUNU DUW-02S frequently over the past year or so, without a single issue. That makes the Z12 cable's modular system all the more disappointing.

Maybe the new DUNU SA6 will have a DD? I’m joking, of course.
Now I only heard him say he was possibly doing the SA6.....that’s all I know? Then that collaboration meme shows up, so I’m guessing.

How did you find the mid bass? I am wondering why it is wooly for me when I use an aftermarket balanced cable, however not so much on the SE side of things. Do you have a similar experience?

Can't understand why the WHIZZER HE03D is not appreciate by the forum... All people talking about dynamic (and planars more recently) and this Dynamic driver technology is one of the best package on the 150€ price range

What’s that o-ring on the nozzle? Maybe band-aid solution to the fit problem?

These IEMs look fancier on picture than in real life for sure :beyersmile:

Wow what eagle eyes you have! Yeah this o-ring thing wasn't on the original OLA!


Will wait on it to see how they much clarity they have on the bass end !!! Waiting on your review.

Will probably be giving this a miss, the fit didn't agree with me on the original OLA.

The original OLA is very technical though, would be a good set for gaming even, and I daresay it could match the HZSound Heart Mirror in terms of technicalities. If you or the others are getting one, look forward to your opinions!

My last night with my best IEM's. I'll be going to sleep with my DUNU EST 112 for the last time. I have to send them off in the mail, as I sold them to fund an iBasso DX170 to replace my defunct Hiby R5 and R2, and the TANGZU Wu Zetian. I will miss thee EST! You have been so good to me.
They are one of the best DUNUs for sure.
Sorry for your lost
