some background to add: i’ve been trying and testing audiophile ear/headphones since around 2017 and this is the pair that got me wanting to write a review. so far the order has been akg k 240 mk Il, creative aurvana live!, beyerdynamic dt 770 Pro 80 ohm, google pixel buds pro, hifiman edition xs, and now the dunu sa6 mkll.


review: i got these as a mobile complement for my edition xs, i wanted a pair of iems less clinical than my xs so i tried picking one that looked interesting and with a bit of unique character. though the sa6 ended up becoming my main pair after an emergency to my edition xs.

and i have to say after a few months of only using these for home, i’m pretty impressed.


the sound signature: is fun, engaging, and expressive, a personal favorite of mine out of what i’ve tested. just enough of a bump to the bass and tweaking of the timbre to always keep me lost and immersed in the music, regardless of whatever genre i’m in the mood for


the soundstage: is good enough that i haven’t been missing my open back headphones like i thought i would. it is more than enough to satisfy me, and i’m more than happy to make these my endgame for the time (and budget…) being


the bass: balanced armature bass can be controversial from what i hear. granted these are my first ba drivers but from what i’ve heard in comparing sa6 to my dynamic and planner magnetic pairs, i think the bass here is probably my second favorite. the only pair i’ve tried that i feel outclasses the sa6’s bass is the edition xs. it’s full, deep, and with just enough rumble to help satisfy my growing house, techno, and dnb addictions


the mids: are enjoyable, detailed, and immersive. the vocals still tug on my heartstrings even with them being less of a priority in the sound signature


the timbre: isn’t earpiercy like my beyers or metallic like the edition xs, so i’m more than happy with it. i actually got these because i read they were smoothed out a bit, making everything so enjoyable and easy to listen to, from harsh noise to lofi black metal and low bitrate electropop.


which also ties to comfort: i’ve never actually got any fatigue or discomfort from these, even after using them over 14 hours a day. in fact, i’d even go as far to say they are the most comfy things i’ve put in my ears. though comfort with iems are mostly anecdotal with how much ear size and comfort varies per person.


i’m very satisfied with the sa6 mkll, and until they break i’m content to stick with them for however long that is, as for headphones… the aryas look very tempting

Review Of The Dunu SA6 MK2​


IMG_4314 2.jpeg


Introduction​


DUNU is a reputable firm that specializes in manufacturing cables and other electro-acoustic goods. Additionally, they offer their own line of eartips called Candy and S&S. The firm was commended for its technology and quality, and it was among the first to create modular cables with modular termination connectors. I have adored all of their IEMs, including the Vulcan, Kima series, Tales, SA6, and others, because of their excellent build quality, excellent sound quality, and superior aesthetics. I managed to obtain a pair of DUNU SA6 MKII for review purposes, despite the fact that it has been some time after their debut, but before, I would want to address a few points.

IMG_4312 2.jpeg


Disclaimer​


*This is a review unit, courtesy of Concept Kart. All thanks to them for providing. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “SA6 MKII.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the SA6 MKII based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​


Six balancing armature drivers make up the multi-driver arrangement of the SA6 MKII. Two Sonion woofers are used for low frequencies, Knowles twin midrange drivers are used for middle frequencies, and Knowles dual treble tweeters are used for high frequencies. Through a three-way frequency crossover, all of these drivers are connected and regulated. Unlike its predecessors, which had a more bespoke-looking shell from the nozzle side, this one is incredibly ergonomically designed. At the end of the day, they appear really different from other IEMs, so I would advise trying it before making any decisions. There were no problems or weariness felt when wearing or using it, even after listening for a long time. The faceplate is made of wood and has a layer of resin applied to maintain its original appearance. The DUNU Hulk mini cable, a premium two-pin cable with modular plug attachments at one end, is included with the IEMs. Additional accessories that come with the IEM include a carrying bag, modular plugs (3.5mm and 4.4mm), a cleaning brush, eartips in a variety of sizes, and a 3.5mm to 1/4inch connector. Regarding the technical details, the sensitivity is 114dB and the impedance is 24Ohms. The frequency response spans from 5 Hz to 40 kHz, with less than 0.5% of total harmonic distortion.

Sound​


The balanced tuning of the SA6 MKII favors the mid range, making the sound open and more expressive, while the treble's spacious and airy response balances it out. The SA6 MKII's response is quite subtle and soothing, yet it's not depressing or laid back in the slightest; rather, it elicits an enthusiastic response rather than a tranquil one. The response is more in line with what I would have imagined from my Monarch MKII when compared to the SA6 MKII with Monarch MKII; nonetheless, the bass and treble are not as deep and expansive.In my perspective, the SA6 MKII is exceptional because, even after being advanced in the upper frequencies, it still sounds remarkably natural and smooth. While none of its competitors can equal what DUNU has accomplished with the SA6 MKII, it can still compete with IEMs that have tribid or hybrid drivers installed. What makes the BA so good is its ability to balance secure and polish with clarity and details. Let's take a closer look at the sound.

IMG_4313 2.jpeg


Treble​


The response of the treble area is quite calming and revealing, allowing for a safe and comprehensive response to that doesn't come off as aggressive. I mean, this is the first time I have heard a smooth response in the upper frequencies while still generating amazing details—especially when it comes to an all-BA set. The vocals, which often sound open and forward, don't appear to come over as such in places where the upper treble, which has excellent air and wide response, seems a touch muted. Conversely, the tones of the instruments are lively but round; they don't sound harsh or metallic. The lower treble brings the notes forward and vibrant, all the while sounding forward and with a strong feeling of tonal correctness. The response highlights the light and energetic sound of the instruments and singers, while also exhibiting lean features that may deviate from a natural sound. However, the impact of these notes isn't heavy, which may disclose such response. As a result, the treble region's overall appearance is vast, light, and calming.

Mid Range​


In terms of the mid range, I was astounded by the contrast and intricacies that each note could offer; the delicately smooth yet crisp intensity created a soothing and invigorating sound. The primary cause of it was that neither the instruments nor the vocals were really thrust forward. The note sounds a little different in my opinion because of its occurrence and unusual presentation without depending too much on energy, which also suitably separates the vocalist's presence from the surrounding instruments in a large area. Similar energy was resonant in the upper mid range as in the lower treble, but the presentation is more enjoyable to listen to. However, while listening to livelier or even basic tunes, the voices occasionally tend to sound off-key. The instruments and vocals sound clear and beautifully detailed, especially the female vocals, which captivate and enliven you with their light and open response. The voices and the instruments seem upfront and dense, but not thick or heavy, which drowns out and leaves the sound wobbly and mumbly. The lower mid range plays a significant role in creating this lively yet peaceful response. The notes should have depth and thickness; some may claim that they do, but I think it sounds a little strange and odd. The clarity in this area also contributes to the sound's pleasing quality. However, once more, the notes are helped in by the dense response produced by the lower mid range. Compared to thin, the higher frequencies should sound more genuine. As a result, the mid range area is presented in a pleasant, revealing, and fascinating manner overall.

Bass​


Getting to the bass, I think it makes the entire response right. By which I mean that the bass responds very well, allowing for a more controlled yet effective response that influences the warmth into the lower mid range. Although many people may be aware, the BA bass has a certain quantity and quality to it. It used to sound more puffy than thump, but that is usually not the case these days. In contrast, the SA6 MKII exhibits a more punchy and rumbly bass instead of a thumping and booming sound because the bass is more prominent in the sub bass region. Although the quantity of the guitar slams isn't quite there, they do sound satisfying. However, I do agree that the bass has a nice, detailed, and controlled feel. Like previously indicated, the mid bass has a good heft and presence but doesn't sound particularly powerful or engaging—rather, it sounds warm. The emphasis is in the subbas region, which tends to sound deep and punchy. Ultimately, I think the bass is done really well; I'm not sure about the earlier models, but I do think this pair is unique compared to others on the market, particularly its competitors. Overall, the bass response is punchy, rumbly, and controlled in its presentation.

Technical Performance​


The technical skill of the DUNU SA6 MKII is another feature that makes me adore them even more. I think that every aspect of them, from the imaging to the layering to the details, is done to the highest standard. I find the SA6 MKII to sound more refined and immersive, even though its peers have a more expansive, open, and vast sounding response. However, even the stage is quite roomy; let's delve deeper into the specifics.

IMG_4309 2.jpeg


Soundstage, Sound Imaging & Separation​


The response is more holographic, the notes are firmly present and positioned to create a very nicely staged presentation that is nicely spread out, and because the stage is not greatly expanded, the presentation becomes more engaging. It was a surreal experience for me because of the crisp, clear imaging that enhances the overall clarity of the notes and the precise layering and separation that makes the notes stand out more.

Speed & Resolution​


The resolution of this all-BA IEM is the best I have heard of, but the details are not crisp or metallic—rather, they are smooth but not soft, with the micro details being particularly notable as well as the macro details are also certainly revealing. Although I find the notes' attack and decay to be a little off, their rapid pace effectively resolves the presentation and prevents it from sounding disorganized.

Sound Impressions ​


Bass Switch​


Although I didn't think there was much of a difference, it was effective where it mattered. The response did sound less thrilling and more balanced in the higher frequencies when I turned on the switch. Additionally, I discovered that the thinness that occasionally surfaced when I listened to upbeat music or, more especially, female vocals, was subdued and seemed more realistic to me. Although the bass felt strong and powerful as well, which contributed to the bass sounding more pounding and dynamic, I think the bass of the dynamic driver is far superior. I found the differences to be subtle, but for other listeners, they will have a greater effect.

Sources​


Sony WM1A - The response from this pair was exactly what I could have hoped for when listening to SA6 MKII with the WM1A. It sounds very wholesome and well-balanced because of the notes' roundness and fullness. Whether it's the vocals or the instruments, both maintain the same level of quality and quantity while adding a comforting warmth. Although the same can be said for the other sources I tried, I think this pairing has a more natural presentation and heavier notes. The treble sounds more expansive and removes the subdued effect, while the bass is also less controlled and causes a natural decay.

IMG_4310 2.jpeg


Tempotec V6 - I find that the more transparent and detail-revealing sound of the SA6 MKII when paired with the V6 sounds a little too expressive. The vocals frequently start to sound metallic because the response is more focused on the upper mid range and lower treble while the bass is more in control, making it sound a little sharper than before. However, I find that listening to tracks with a lot of bass has a very enjoyable and fun sound quality because of the impact and cleanliness of the bass as well as the sparkling high notes.

IMG_4311 2.jpeg


Kiwi Ears Allegro - When listening to SA6 MK2 with Allegro, the sound seemed more personal, which made it easier to understand the notes' sharpness and differentiate them. The response was all pushed forward, from bass to high, yet the coherence and balance in between seemed organic and seamless. However, I did notice that listening to busy or complicated tunes made it difficult to pick up on subtleties because of the forward and near response, but the bass also felt more prominent and forceful. Even yet, I continue to like its meticulous and sterile presentation.

QUESTIONS & ANSWERS​

  • Can you confirm that the MK2 will have the same 60Ω impedance as the original SA6?
    Hello, not the same, according to the existing specifications, it is not 60Ω. MK2 is 24 Ω impedance. Thanks
  • What is the sound signature of new SA6?
    1. Refined treble response improving clarity.
    2. Better fit and noise isolation due to more secure fit.
    The 3-5 kHz dip was adjusted for better vocal clarity and instrument separation.
    3. Better bass and treble extension while maintaining the resolution.
    4. Default mode is Ultra with a slight bass boost and improved treble.
    The switch now completely changes the bass response, focusing especially on the subbass and middbass without affecting vocals or clarity.
    5. By increasing the bass on the MKII, the listener will experience a more engaging sound while still maintaining a clean midrange. The bass mode on the MKII provides even more bass than the standard mode.
    6. The MKII's upper midrange is smoother than ultra, which results in a more accurate representation of vocals and instruments.
  • Is it easy to drive?
    It is easy to drive. Easier than Z12, Starfield, Blessing, Timeless, P2 etc
  • Is the cable same as OG SA6 or Ultra ?
    It is Hulk mini pro cable same as Ultra, but without 2.5mm jack in MKII due to a lack of interest from the users, and this also helps to cut costs and make the SA6 MKII more affordable.
  • I have purchased before, but it is small for me, what are the size for eartips in this time?
    We listened to other buyers' suggestions for the same S&S earbuds as before, but this time added a 13mm XL size for the S&S eartips.
  • Is the MKII comfortable to wear?
    The MKII have been optimized for the most comfortable wearing experience while remaining stylish.
  • What does the switch on the MKII do?
    The switch on the MKII changes the sound signature from neutral with a slight bass boost to neutral with a bigger bass boost and noticeable clarity and air and is best used when listening to music that requires a more pronounced bass response. This includes genres such as hip-hop and EDM.
  • Are the red patterns on the faceplate the same for each IEM?
    No, each IEM has a unique set of red patterns on the wooden faceplate. This adds to the individuality and exclusivity of the product.

The uncertainty of shell face pattern is a concern of hate or like.
I had EE hero before, it has swirl pattern like this one and made "Hero" almost unseen from the face, which looked bad.
