In 2013, DUNU changed the premium hybrid in-ear game with the DN-1000. It was one of the very first non-kilobuck hybrid designs around to offer a clean, clear, and balanced sound profile, Its successor, the DN-2000 and 'J' variant were even more successful.

Today, the DK-2001 updates the DN series of hybrids to our over-ear wear style seen in our DK series. We also update the tech to 2020 standards, bringing to it a number of key improvements, with an increased driver count and a beryllium dynamic driver only being a couple of its notable enhancements.

DK-2001_Topaz.jpg

Second Generation DK Ergonomics & Upgraded Shell Materials

First and foremost, we made comfort a priority. The shells are designed for all-day wear and utilize second generation DK ergonomics, which debuted with our flagship DK-4001 and was carried over to the DK-3001 PRO. The tip stems are machined with a lip so that tips don't slide off easily, and the insertion angles have been optimized for a wide variety of ear shapes via a computerized database. The shells are also machined entirely from 316 stainless steel, it is more wear and corrosion resistant than the 303F stainless steel used in the DN-2000 series. The removable cable connectors are our own Catch-Hold® variety, which is our proprietary take on the MMCX connector that is compatible with all other MMCX cable interfaces out there.

Then, we switched up our style. In the past, DUNU has stuck with the tried and true black or polished chrome look. The DK-2001 will now be offered in three color anodize options: Topaz, Obsidian, and Turquoise*.

*Note: Turquoise will be not be offered at launch, but at a later date.

Acoustic Design

With three custom-spec Knowles balanced armature drivers (1 for mid-highs, 2 for highs and super-highs), and a 13 mm dynamic driver for the lows, the DK-2001 follows a similar acoustic design structure to our flagship DK-4001, versatile DK-3001 PRO, and DK-3001.

The 13 millimeter dynamic driver is coated on both sides with Beryllium via an advanced process that allows us to retain proprietary control of the thickness and grain pattern of the PVD coating. Doing so allows us to tailor the low end driver to our tuning goals.

With perhaps more experience designing compact hybrid in-ears than just about every other manufacturer around, we were able to inject a little more color (both literally and figuratively) into the DK-2001 without sacrificing clarity and definition. The result is a highly satisfying sound signature with the fun turned up a notch or two for all manner of music --- especially electronic and pop.

Cable & Accessories

We at DUNU have long prided ourselves on providing users with a rich set of accessories for every product we release. The DK-2001 is no exception. The highlight is the included cable, which features our patented Quick-Switch modular plug cable system. Users will be able to switch between 3.5 mm single-ended, 2.5 mm balanced, 3.5 mm 'PRO' balanced, and 4.4 mm unbalanced/balanced connections with the simple pull of a highly secure circular latch. By default, the 3.5 mm single-ended plug is included with the DK-2001, and users will be able to purchase the other plugs from DUNU.

The cable material itself is no slouch, and is composed of individually-enameled strands of high-purity silver-plated OCC copper, so a Litz Type 1 cable is included as stock. It will also be sold separately as a standalone item called the DUW-02 in the very near future.

A bold-looking cerulean blue leather zip-up case and multiple pairs of ear tips round out the package, along with a few other items that do not need to be mentioned. Essentially, it's a list of just about everything you need to get started.

This seems to be a great value for the money! Will balanced connectors be sold the same day this DK2001 goes on sale?

I literally just ordered DK-4001’s as an upgrade to my DN-2000’s this morning. I might order these anyway as I think the DN-2000 have almost perfect tuning for my tastes and ears.

$279 is the black Friday price.... For those who don't want to search.

Was hoping for lower, sounds like it's going to be a competitor, but that 13mm dual side coated berrylium DD sounds fun.....

I have a feeling it will be a step up from my Oriveti New Primacy. Time to keep an eye on it. Subscribed! :)

Yes! We will have all four modular plugs on sale on the same day. Each one will be $19.

Thanks for the support! While the DK-4001 was a platform for us to take risks with --- how many people are doing a two-way, five-driver hybrid with a bass reflex system --- the DK-2001 was a chance for us to really dial in a sound signature that appeals to a large population, and bring along all the lessons we learned from the DN series of hybrids as well.​

Will you guys offer the option of choosing the default plug it comes with? That would be really cool :)
I would opt for the 2.5mm balanced one since my source has that as the only output.​

Because most people still use 3.5 mm single-ended as the most common jack interface, we ship only with it as default. However, two of our upgrade cables, LYRE and CHORD, ship with a choice of plug (but only with MMCX as a connector), as they are meant to be the next steps in the cable ecosystem.

The following is a table summary of the cables that utilize the modular plug system:

How much later would the turquoise version be available?
There is no clear timetable yet. We'll offer it as soon as our production line is able to support a third colorway.

when is the launch for japan?
That would depend on Soundearth, our main distributor in Japan. They are finalizing a few things, homologating the DK-2001 for the Japanese market. But it should go on sale across Japan by December.
