Sound quality description
In this review, I use the standard eartips size L and drive it with the FiiO M15.
The DUNU SA6 mk2 has a neutral-conscious, full midrange sound signature.
These are fairly expensive earphones, but the sound balance is not very good, at least for monitoring purposes. When driven with an 85-ohm load using an impedance adapter or similar, the sound balance is quite close to that of a legitimate studio monitor. However, the sound performance is a bit degraded in this condition due to increased noise level and other factors.
Please see here for detailed reviews on sound quality.
Lows / Bass
The low frequencies of the DUNU SA6 Mk2 are sufficiently linear and extend quite deep.
The bass drum is quite heavy and has a strong impact, with a fair amount of rumble, but the bottom end is a bit shallow and the sense of realism is lacking.
The electric bass has sufficient blackness and depth, but lacks a bit of spaciousness.
All in all, the bass is adequate in quantity and will satisfy bass lovers in its own way. However, it is not a low frequency that is worth the bother of paying this price to hear.
The midrange of the DUNU SA6 mk2 is staging-enhanced and the texture is not accurate.
The adjustment is not very appealing, at least as studio monitors. Detail, edge, and crunch are also weak, and the overall construction is lacking. If you compare the CCA CXS, for example, with a more orthodox monitor-like sound, you will immediately notice a significant difference in the reproduction of the three-dimensionality of the music.
Transparency is not very high, and resolution is about the same as the CXS, so there is not much need to choose the SA6 mk2 as studio monitors.
The sound image consistency is relatively high, so it is hard to feel any breakdowns, but the ability as studio monitors is quite poor, with vocals too loud, snare too soft and not powerful enough, and lacking a sense of fine detail.
Personally, I only had the impression that it was a boring sound for a price of over $500. The sound tends to become dull and metallic just above the center of the midrange, making it sound tinny. This can be quite unnatural and unexciting.
As mentioned above, this unnatural sound balance can be improved by using an impedance adapter.
Highs / Treble
High frequencies are generally lacking. It seems to have been adjusted with a sense of forward localization in mind, but the sense of definition is also lacking, and the level of detail reproduction is not good.
Extensibility is not relatively bad, but the sense of detail is lacking, so the subtlety of musical expression is lacking. Cymbal crashes are also subdued and lack vitality.
Sound image consistency level is high, so violin and woodwind extension and overtone expression are natural and not bad in terms of extension, but overall the sound is a bit subdued and lacks flair.
Sound quality general comment
These are mediocre earphones for the price, and while DUNU has put a lot of effort into the SA6 and seemed confident in this mk2, there are countless better options available at least at a lower price than this, and they seem to fail to justify the price in terms of audio specs.
When I got this model, I happened to be listening to it in rotation around the EPZ K1, before I measured the SA6 mk2, and it seemed obvious that the EPZ K1 sounded better when compared. I expected that perhaps the SA6 mk2 would not be as good based on the rating values of my evaluation system.
When I actually measured and evaluated the earphones, they were indeed not very good. This is why I have little interest in high-priced earphones, simply because they sound so bad.
And audio products in the higher price ranges are over-hyped and full of deception, where consumers are also deceived into believing that they sound good. I have mentioned many reviews that say things like "$1000-class sound" about these earphones, but before you get your desire aroused by those statements, you should think carefully about what they are basing such outrageous statements on in the first place. You will find that they themselves have no knowledge or data about "$1000 class sound". Eventually, they may say that if they use expensive components, it will sound better.

The DUNU SA6 mk2 is probably the brand's most confident earphone of the year. However, in my opinion, it is a half-baked earphone, as is typical of DUNU's recent releases, with little to see in terms of sound quality and a high price tag overall. The packaging is also mediocre for the price, and while previous DUNUs would have provided a more enjoyable unpacking experience, there is little interest in the SA6 mk2 package unpacking experience. I don't think it is worth the price.
