Review of the Kinera 2.0 Flagship
(Images captured with S21 Ultra in Pro Mode)
The Nanna 2.0 is Kineras latest revision to its well-received Kinera Nanna 1.0. Originally priced at $899, the Nanna 2.0 offers a tribrid configuration consisting of one 7mm dynamic driver for bass, one Sonion balanced armature for mids, and two Sonion electrostatic tweeters for highs. From what I understand there were two releases of the Nanna 2.0. Kineras initial release was the “Flagship” Nanna 2.0 and is paired with the same cable (pure copper with 3.5 termination) and accessories as the Nanna 1.0. The differences are refined tuning and new faceplate art. Then, Kinera released a newer ‘’Imperial’’ or ‘’Pro’’ version of the Nanna 2.0 ($949) that comes with an upgraded cable (silver-plated copper with 4.4 termination) and more accessories but the driver configuration and tuning remain the same. The unit that I purchased is the “Flagship” Nanna 2.0.

Design, Build and Fit
The multicolored faceplate of the Nanna is absolutely gorgeous having a top-tier look while not appearing flagrant or showy. The build quality of the housing is also excellent. The cable is adequate but I wish it was better. I don't like the clear plastic chin slider. It looks cheap and doesn't stay in place. I also wish they would've included a 4.4mm adapter. They do, however, offer a good selection of tips. The nozzle on the Nanna is on the larger side but I experienced no discomfort during long listening sessions. I also used the Nanna for two separate 3-hour band practices and had no discomfort. I achieved the best fit and isolation using the supplied Final tips.
Sound
The sound signature of the Nanna 2.0 is warm neutral. While there is plenty of treble presence above 10k the overall treble presentation is very relaxed. There is a notable upper-midrange presence between 2.5k and 1.5k tokening female vocals and higher stringed instruments. There is a significant elevation that starts in the lower mids and continues throughout the rest of the bass frequencies giving the Nanna 2.0 an overall warm presentation. The result is a very smooth, organic listening experience. Coherency between the three different types of drivers is excellent, among the best I’ve heard.
Treble
The Nanna has excellent treble extension and while on the relaxed side I wouldn't call it dark. Live recordings have ample amounts of air and atmosphere. Symbols sound natural, never sounding harsh or piercing. Detail retrieval is excellent, revealing the most subtle details in symbols and higher stringed instruments. Hi-hats have realistic sizzle and stick attack on drums sound woody and natural. The Nanna 2.0 manages to maintain a very good treble presence without ever sounding harsh or sibilant. The treble of the Nanna 2.0 is buttery smooth. It’s simply beautiful.
Mids
The mids are right where I like them, not too forward, not too recessed. Instruments sound very detailed and natural with good presence and physicality. The lower mids are elevated giving male vocals plenty of body and thickness. As a drummer, I obsess over accurate representation of drum tones. Deep tuned snares, toms, and floor toms sound natural, having very good tactility and realism.
Bass
There is no perceivable bass-bleed into the mids. I love the Nannas warm, full-bodied sound signature and while the low mids and bass are elevated, instruments that fall within those frequencies never sound muddy or lacking in detail. The bass and sub-bass are elevated but tastefully so. The 7mm dynamic driver has very good texture and layering while also delivering excellent slam and punch.
Soundstage and Imaging
The soundstage and imaging of the Nanna 2.0 are excellent. It has a wide 3D presentation that immerses the listener within the sound field. The three most holographic IEMs I’ve ever listened to are the Empire Ears Odin, 2020 CA Andromeda, and the Noble Sultan and while I wouldn’t say it’s as immersive as the Odin or Sultan, I would say it approaches, maybe even rivals, the 2020 Andromeda but with even greater instrument and vocal density. Instrument separation, layering, and imaging are excellent with each instrument having its own defined space within the sound field.
Mest MK1 Comparison
While doing a side by side with the Mest MK1, I noticed the Nanna fell behind in terms of technicalities. The Mest has better detail retrieval, layering and is more resolving. However, I find the overall presentation and tuning of the Nanna to better suit my preference in terms of pure listening enjoyment. And while I wish the Nanna was more resolving I find that its presentation is more substantial and adds more weight to notes giving instruments and vocals increased density and physicality. Definitely not the result I expected.
Power Requirements and Pairing
The Nanna 2.0 loves power. My DX220 with the AMP1 module and iFi Diablo powered the Nanna easily with plenty to spare. However, with my DX220, when I switched to the AMP9 module (tube amps) I found myself having to push the volume up quite a bit more even with the AMP9’s output set to high. However, I still had adequate headroom when I reached my desired listening level. The ZEN DAC and PAW S1 also had no problem powering the Nanna. As expected the Samsung USB adapter and S21 struggled to push the Nanna. I was barely able to achieve listenable volume levels. My favorite pairings were with the DX220/AMP9 and the ifi Diablo. The DX220/AMP9 provided a very organic listening experience while the Diablo was less warm and more detailed.
Conclusion
With reviews ranging from ''my favorite IEM ever’’ to “tuning barely worthy of its price’’ it was difficult knowing what to expect from the Nanna 2.0. But honestly, the “unknown’’ factor is what makes these kinds of reviews so much more interesting. In these circumstances, I set my hopes high and expectations low by default. Thankfully, the Nanna 2.0 confirmed my hopes and dramatically exceeded my expectations. Interestingly, some of the negative reviews were coming from reviewers I follow quite closely and generally align with. Regardless, my experience with the Nanna 2.0 only serves to confirm that we all hear and process sound differently. So far, my experience with the Nanna 2.0 has been nothing short of impressive. Its buttery smooth highs, warm mids, and impactful bass keep me coming back for more time and time again. And while I'm not prepared to declare it the best in it's price range, I can easily say it's capable of holding its own among the best in the $1,000 price range.
I think the cable is very good, I prefer the heavier cable that came with my DUNU SA6 but a lot of people complain about that one so it’s personal preference.
