Indeed, it should be less than $400. This is probably some kind of store specific markup.
Ah didn't know. Just saw it today when I was looking up some information.
This cable is great, especially with its dedicated copper shielding layer. It's pretty much one of a kind in the realm of IEM cables.

Where do you get this 17th set?If you have Weibo, there are a ton of pictures, but here's a link: https://zhuanlan.zhihu.com/p/77735054 (NOT a purchase link)
From all I can see, it is intended as a "coming of age" anniversary for DUNU, which has really shown off its new, more mature sonic tuning strategy in spades this past year.
The 17th anniversary model is the DK-4001 retuned as a pure dynamic driver model, and with a matte silver anodize (instead of black), as well as a wire without the exclusive copper shielding of the cable included with the DK-4001.
It seems offering special price $3599RMB for some?

As far as I know, that is a China specific promotion, and understandably, this limited edition model will mostly be reserved for the Chinese. Additionally, a good proportion of those 500 units will be gifted to friends and longtime supporters of the brand. What is leftover will be sold. For example, only 20 units were allocated for sale in HK. It turns out just about all of them were accounted for by the end of the HK AV show a couple of weeks ago. I don't know when it'll be available internationally.

Thanks for that, I will watch later when I'm back from work, but if you didn't say its the best IEM for the money out there then you are wrong.
Eeeeh, my take was a bit more critical of this one in particular, didn't hit me as well with its sonics as DK-3001 PRO , for example, which although cheaper and also made by Dunu, hit me from the first second of hearing it.
1. I actually didn't know, interesting. I only saw that they have 4 drivers, and that one is a Berilyum, which people usually use for bass rather than wide frequency
2. Sorry, that was my mistake, I read 899 USD and probably thgought 800, although in Europe that would be about 1100 USD, because of VAT and other taxes

I've now spent around two weeks with the 3001 PRO. On a technical level, I'm of the opinion that the DK-4001 is much better than the DK-3001 PRO. Not that the 3001 PRO is bad, but with the 4001, I hear deeper into the sound field, sense more realism with timbre, feel far better bass extension/texture/layering, and hear better treble extension, even.
I feel I should dispel the myth that the 4001 has bad treble extension. It is shelved in the treble, indeed, but I hear no odd truncation in high frequency harmonics like I do with earphones that do have bona fide extension issues.

Listening to the 4001 right now on the go. Had it for more than 6 months and still very much enjoy it. Small and comfortable easy to use, sound quality is obviously

Hi there,
My impressions about the DUNU DK4001 are very positive. It shows a great bass performance offers a musical and detailed midrange presentation and has a treble range that is smooth and controlled. In addition, it comes in a premium looking box that is full of high quality accessories. Everything looks first class, while the build quality of the monitors and of the stock cable with the patented quick switching connectors is absolutely solid! All in all, the DUNU DK4001 is one of my favorite in-ear monitors in this price category.
Here are some Pros & Cons:

I've updated the index post with up to date information.
EDIT: A little bird told me I missed a review or two, so I updated the information to reflect the Headfonics review. I'm a human, and not a machine learning content aggregator, so I will make mistakes here and there!

Has anyone been able to compare these to the Oriveti OH500? I am thinking of picking up either the DK4001 or the Oriolus, for a trip I have to take.

Don't you mean Orivety OH500? Anyway I have not heard them so can't help you.

You mean Oriveti, right? It seems @audio123 has reviewed both, so perhaps he should chime in.
I've not heard the OH500, nor any other Oriveti earphone for that matter, but I can offer some thoughts:
- The OH500 is a $499 product, so it is competing with the DK-3001 PRO ($469), FiiO FH7 ($449), and Moondrop Blessing ($399) --- all 4+1 hybrids in the same price range, rather than the $899 DK-4001; of course, it doesn't mean the OH500 doesn't punch above its weight, but all the previously mentioned hybrids are already really good values at this price point --- it's hard to imagine the OH500 topping them, TBH
- From a construction standpoint, the OH500 is hand-built from acrylic resin; it makes sense that a builder uses hand-cured acrylic resin to offer fancy shell designs, but the Oriveti is a simple single color with no real artwork to speak of. While the build quality looks really good (no discernible bubbles or other imperfections), hand-cured thicknesses will vary from unit to unit, as opposed to 3D printed resin shells. It seems like the OH500 was built this way for the following reasons: (1) Oriveti didn't want to spend the money for an injection mold, or precision CNC, (2) Oriveti didn't want to spend the money on 3D printing the shells --- these are manufacturing tactics that builders use when they only want to make small quantities
- On the other hand, speaking from personal experience, both the FiiO FH7 and the DK-3001 PRO are impeccably built with CNC construction methods. The DK-4001 is molded with ZIrconium alloy, which is used by the likes of the Sony IER-Z1R and Campfire Lyra. It's not a super expensive material (the $219 Dunu Falcon-C also uses it), but it's super difficult to work with and get good yields, especially if you want a nice polished finish. The Moondrop Blessing is still a resin shell, but AFAIK it's 3D printed, so SQ, fit, and build should be slightly more consistent than the Oriveti
- From an accessories standpoint, the DUNU offers a convenient modular cable set; the DK-4001 has a really high-end cable (it is pure silver and OCC copper individual strands, with a copper shielding layer, which is super rare, and that's why it's configured in a compact twisted pair rather than a braid, because it's less affected by crosstalk and interference issues), while the DK-3001 PRO has an OCC copper cable. Both have the super convenient modular plug system. Of course, if you don't have multiple source DAPs or DACs, then the plug system is probably of marginal utility. The FH7 has exchangeable tuning filters and a rich accessories kit. I don't see the Oriveti topping them.
- From an acoustic technology standpoint for the dynamic driver, the Oriveti uses an 8 mm dynamic driver (no indication of any kind of surface treatment, so I'm assuming it's a polymer like PEK without titanium/LCP/beryllium bonding). The FH7, DK-3001 PRO, and DK-4001 all have Beryllium-coated diaphragms (dual-sided) at approximately 13.5 to 13.6 mm in size. The DK-4001 additionally uses ACIS, which is a bass reflex load adjustment bass venting spiral that enables better bass extension under tight response. The DK-3001 PRO has no ACIS and uses a different thickness of Beryllium bonding than the DK-4001. The FH7 has S.Turbo, which is essentially an acoustic low-pass that minimizes bass driver interference with the BAs. I'm not sure what the Moondrop Blessing is like. This all means that all 5 models will offer very different experiences in the bass. If you ask me, out of these models, I feel the bass on the 4001 is the best textured, best layered, and best extended. The combination of the Beryllium coating with ACIS (which is specially mated to each other) makes for a special experience. The FH7 comes next, with a nice low end, followed by the 3001 PRO, which has a more relaxed sounding (but more voluminous than both the 4001 and FH7) bass response. I don't know what the Blessing uses, or is like in real life.
- Examining the Oriveti, I see at least a DTEC driver inside (it's DTEC because they use Knowles), which will be a nice midrange driver, so I'm assuming it uses an SWFK for the highs (judging from the FR peaks). Contrast this with the FH7, which uses a custom DFK (which will usually offer a "smaller" sound than the DTEC, but more etched), and an SWFK, or the DK-4001 which uses two SWFKs (midrange to upper midrange is still the Beryllium driver), or the 3001 PRO, which uses two custom Knowles midrange drivers (they are probably RAB/RAF drivers, judging from the size), and an SWFK for the highs. The Blessing uses either a custom Bellsing driver or a Sonion 2800, or a rare Knowles RDA driver for the midrange, and what looks like either a Knowles SWFK, or the Bellsing SWFK alternative. What does this all mean? It means that the 'qualia' of the treble will be more similar than not across all of these models, but they can definitely be very different from an FR, phase, and distortion perspective. The DK-4001 will likely have the least distortion, because two SWFKs stacked will decrease distortion and increase headroom (this is what JH Audio and other CIEM makers do), while offering the most dynamic-like midrange presentation. The DK-3001 PRO sounds more diffuse in the treble than the 4001. However, despite it also having the SWFK within the front of the bore like the FH7, the 3001 PRO and FH7 have very different presentations in the treble. The FH7 is more intense and at times splashy, while the 3001 PRO is thinner and more spaced out. Of the three that I've heard, timbre is most realistic on the 4001.
- From an FR tuning standpoint, if we look at @crinacle's measurements, the OH500 looks decent, albeit with with an ~8 dB boost in bass over a diffuse-field type of tuning. The FiiO FH7 and DK-4001 will all have less bass response. The DK-3001 PRO might have a similar level of bass, but there are no definite measurements to corroborate my estimation. You can play with the FR comparison tool to look between the FH7, the DK-4001, and the OH500. The Moondrop Blessing is close to near-textbook Harman targeting and has @crinacle's seal of approval (if that means anything to you).
- Overall, and take this with a grain of salt, because I have zero experience with the OH500, but my gut tells me you'll get a better buy with the models I mentioned. If you're looking for a similarly priced item to the OH500, you should look at the DK-3001 PRO or the FH7. Both offer a package that I feel beats the Oriveti in overall value and utility. The construction of these two models is likely to hold up better over time compared to the Oriveti as well. This matters if you intend on using it for a long time (rather than buy and sell after a few months like many people do on her). And because this is the DK-4001 thread, I have to finish with stating that the DK-4001, from construction to sound tuning, is a true flagship statement from Dunu. They took their time with this model, and it shows. It might not be for everyone, but it has TOTL qualities to its sound that are undeniable.
