DUNU × Gizaudio DaVinci Review – The Art of Warmth
2 × Dynamic Driver + 4 × Balanced Armature per side
The DUNU × Gizaudio DaVinci was released in mid-May 2024. The original retail price was 299.99 US dollars. HiFiGo currently asks 289.99 dollars, GeekWills still lists it for 299.99 dollars. At HiFi-Passion it is listed for 299 euros, although it is currently out of stock there. Amazon Germany and Amazon US still have product pages for the DaVinci, but currently without a regular visible Featured Offer.
The DaVinci is a collaboration between DUNU and Timmy from Gizaudio. After Galileo with LETSHUOER and Chopin with Binary, it was Timmy’s third major IEM collaboration and his first with DUNU. What I find interesting is that the tuning was not simply approved behind closed doors at some point. After demonstrations at CanJam Singapore, the final tuning was adjusted again based on the feedback collected there.
I bought mine used at the beginning of 2025 and took it straight with me on a short trip to Bonn, the former capital of Germany, back when Germany was still divided by the Wall into East and West Germany. I can recommend it to anyone visiting Germany, completely different from the current capital Berlin, somehow cosy, friendly and playful. Really beautiful, just like the DaVinci. Wow, what a transition from me. 😊
I still like it very much today and for me it has become an indispensable part of my collection. The DaVinci is simply a great musical product.
The name DaVinci fits surprisingly well. Leonardo da Vinci was not only a painter, but also an engineer, draftsman and inventor – someone where art and technology constantly came together. That is exactly what DUNU is trying to do here as well: an eye-catching wooden faceplate on one side and underneath a fairly complex 2DD+4BA setup with five ways and five separate sound channels.
The foundation is powerful, warm and full-bodied. Above that, the mids remain surprisingly complete and the presence region is built up in a controlled way, while the treble stays rather relaxed overall.
A Few Words About DUNU – Part 1
DUNU is a very experienced ChiFi brand.
DUNU is based today in Dongguan in the Chinese province of Guangdong. DUNU itself names Dongguan Dadian Electronics Co., Ltd. as the company behind the brand, where development and manufacturing are located. Historically, DUNU comes from the TopSound environment.
The company began developing and manufacturing headphones and earphones in 1994. That makes DUNU older than quite a large number of the brands we regularly talk about today.
DUNU initially worked heavily as an OEM/ODM manufacturer and developed or produced products for other companies. Only later did its own brand move more strongly into the international spotlight. A former DUNU executive once described the early days in retrospect as an OEM business with structures in Taiwan, Hong Kong and China.
In the early 2010s, DUNU became increasingly visible in the international IEM scene as well.
Models such as the DN-1000, DN-2000 and Titan 1 made the brand known outside China. The DN series in particular was already using hybrid constructions quite early, while the Titan 1 stood out among other things with its titanium-coated Dynamic Driver.
Multi-driver hybrids are not some trend DUNU only jumped on yesterday. There are people working there who really know what they are doing and you can hear that. In my opinion you can hardly go completely wrong with a DUNU IEM, somehow they are all pretty good.
Some of the people behind DUNU are very well known in the audio scene. Mike Sun was introduced as CEO of DUNU TopSound, while Andy Zhao, as senior acoustic engineer and head of Chinese manufacturing, was involved in several important projects. DUNU not only handles development and assembly, but also owns its own measurement and development facilities including an anechoic chamber.
They have been doing all of this for quite a while, I would really like to see it in person one day.
Technical Specifications
Driver configuration: 2DD + 4BA per side
Subbass: 1 × 10 mm Dynamic Driver
Bass: 1 × 8 mm Dynamic Driver
DD diaphragm: Bio-Cellulose Dome
Mids: 2 × Custom Balanced Armature
Treble: 1 × Custom Balanced Armature
Ultra-high: 1 × Custom Balanced Armature
Crossover: 5-way
Acoustic sound paths: 5 separate tubes
Impedance: 35 Ohms @ 1 kHz
Sensitivity: 109 dB/mW
Frequency range: 5 Hz – 40 kHz
Connection: recessed 0.78 mm 2-Pin
Weight: approx. 6.6 g per side
Cable: DUNU LEO
Plug: modular 3.5 mm + 4.4 mm

The 10 mm DD handles the sub-bass, while a separate 8 mm DD takes care of the rest of the bass range. Both Dynamic Drivers work in separate chambers.
Above them sit four custom BAs that are really well tuned and do not need to hide behind Sonion or Knowles BAs. I honestly hear no difference at all! Compliments to DUNU.
Two of them handle the mids together, followed by a dedicated BA for the treble and another one for the ultra-high range. DUNU does not disclose external OEMs or specific model numbers for these four BA drivers.
On top of that there is a 5-way crossover with five separate acoustic sound paths.
The internal structure was implemented together with HIGETECH. Using high-resolution 3D printing, the individual acoustic channels are integrated directly into the shell structure.
I also like the separation of the two Dynamic Drivers for sub-bass and midbass.
Unboxing, Build Quality and Accessories
The packaging picks up the DaVinci theme. The beige or cream-coloured outer box is decorated with drawings and technical sketches reminiscent of Leonardo da Vinci’s manuscripts. Underneath sits the actual sturdy inner packaging.
The complete package includes:
DUNU × Gizaudio DaVinci
DUNU LEO Modular Cable
3.5 mm module
4.4 mm balanced module
3.5 to 6.35 mm adapter
10 pairs of eartips
DUNU S&S Tips
DUNU Candy Tips
DUNU Standard/Olive Tips
large zipper case
cleaning tool
documentation
The ten pairs of tips are spread across three different tip families. These include the well-known DUNU S&S, the softer Candy Tips and a more traditionally shaped silicone tip.
I use the S&S Tips.
By now probably everyone who has gone a little deeper into the IEM swamp knows them, otherwise get yourself some, they can take some IEMs to another level and also solve fit problems. The DaVinci does not really need that though, it also sounds wonderful with the other tips.
The Candy Tips are more traditional in construction and are softer and rounder.
So tip rolling can start straight out of the box, sometimes that is fun too.
The included cable is called LEO and was developed by DUNU for the DaVinci.
It consists of four strands of high-purity silver-plated monocrystalline copper and uses a braided Litz construction. On the IEM side there are recessed 0.78 mm 2-Pin connectors.
DUNU uses its modular plug system and includes both 3.5 mm single ended and 4.4 mm balanced. That is how I like it.
There is even an additional 3.5 to 6.35 mm adapter. So from a smartphone dongle all the way to a desktop amp, basically everything is covered straight out of the box.
The large rectangular zipper case with the DUNU logo offers considerably more space than just for the two IEMs. Cable, modules, tips and other accessories can all disappear inside together. It has proven itself so well that it is still included with current models such as the new DUNU 242.
The actual shell is made from skin-friendly resin and manufactured using high-precision 3D printing.
On top sits a faceplate made from stabilized natural wood. Because of the natural grain, the individual faceplates are never completely identical, giving every pair a little bit of its own character.
At 6.6 grams per side, the DaVinci remains relatively light despite its six drivers. The 2-Pin sockets sit recessed in the shell and the nozzles bring the five separate acoustic paths together.
Sound
The DaVinci sounds warm, full and powerful, without simply burying its mids underneath the bass.
It is simply very musical and easy to listen to for long sessions, if I had to describe it in simple terms.
Bass
The DaVinci has a lot of sub-bass, a powerful midbass and plenty of body as a result, but it still stays clean enough away from the mids.
Of course “Angel” by Massive Attack fits perfectly for testing this.
The bassline is already there very early in the track and builds this dark, heavy underlying mood throughout almost the entire song.
The DaVinci turns it into exactly what I want to hear from this kind of tuning:
Weight.
The sub-bass stands deep and big in the room, above it the midbass gets enough punch so the whole thing does not just rumble around down low.
As more and more elements are added later in the track, the foundation remains present.
The DaVinci sounds beautifully rich.
Mids and Vocals
Despite the large amount of bass, the mids do not disappear. Vocals have plenty of body and especially male vocals benefit from the warmth coming up from the bass region.
Here we take “Way Down We Go” by KALEO.
At around 0:15 Jökull Júlíusson’s voice stands fairly free in the room and immediately shows what the DaVinci does with male vocals.
It sounds powerful, full-bodied and dark enough, without being completely buried.
When drums and bass become stronger later on, the voice remains clearly recognizable and continues to sit cleanly above the foundation.
Lots of bass and still no half a voice. Really good.
Presence
The presence region rises in a controlled way and gives vocals, guitars and snare drums enough contour.
“Go Your Own Way” by Fleetwood Mac is our test track here:
When the song really kicks in after the intro, you quickly notice whether a warm IEM has enough energy to lift guitars and drums out of its bass foundation.
The DaVinci does. The guitars remain present and the snare gets enough attack.
Treble
The treble is rather smooth and controlled, it delivers enough information and shine, but stays deliberately a little more relaxed compared with the bass and mids.
Let us stay with Fleetwood Mac and put on “Dreams”. Oh and turn it up, Fleetwood Mac is meant to be played loud.
The hi-hats and cymbals run through practically the entire track and are excellent for hearing how an IEM handles longer passages of treble material.
The DaVinci presents them cleanly, but does not constantly push them forward.
That is smooth, and it fits its whole character.
Soundstage and Technical Abilities
The stage feels rather medium-sized, but has good depth layering and clean spatial organization.
“Hotel California – Live on MTV, 1994” by Eagles, we have used that one a few times already as a test track:
After the long intro, guitars, percussion, bass and finally the vocals are added one after another.
The individual layers remain cleanly organized and the warm tuning gives the whole performance a beautiful sense of spatial depth. Separation and layering are good.
With very complex and fast music though, you notice that the DaVinci is tuned more for body and naturalness than for maximum speed and surgical micro-detail.
Conclusion
What can I say?
Buy this thing while it is still available, I am going to buy another new one myself, because back then I bought a used unit where the cable was slightly damaged. Simply a must-have – not just for collectors, but for people who love music.
The DUNU × Gizaudio DaVinci shows pretty well why DUNU has survived in the IEM business for so many years.
The two separate Dynamic Drivers, five ways, five acoustic tubes, four BAs, HIGETECH shell and the modular LEO cable deliver a beautiful sound that you just want to enjoy for a very long time.
Warm. Powerful. Full-bodied.
The DaVinci is bass-heavy, but still balanced.
And Timmy? After Chopin and DaVinci I have to give him at least this:
The man knows how to tune.
With that said, let us stick with DaVinci:
Knowledge is not enough; we must apply it. Willing is not enough; we must do it.
Yours,
Faxe.
