Newly developed 13mm Beryllium Diaphragm Dynamic Driver adopted the beryllium coated technology, utilizing its lightweight advantage and the high elasticity and rigidity acoustics character, bringing out the powerful and responsive bass to its max level and delivering a well defined mid-low frequency range.
Precision machined S316 stainless steel housing combining with scientific design, it effectively eliminates harmonic resonance to enhance sound cohesiveness, as well as to achieve a clean and crystal clear sound experience.
OUR MOST VERSATILE MODEL YET.
Expertly tuned to be the ultimate in balance between detail reproduction, soundstage ambience, and long-term approachability, the dk-3001 pro is our most versatile model yet. Bass is accurate, yet rumbles with proper authority. Vocals are full and voluminous. Harmonics glisten ever so slightly in the treble region.
The hybrid low end is anchored by a massive 13 mm dynamic driver with a beryllium-coated diaphragm, bonded on both sides via a specialized physical vapor deposition process developed in-house by our team of acoustic engineers.
Knowles corporation, the global leader in balanced armature technology, is our esteemed longtime partner in providing us with the balanced armatures responsible for the rest of the audio spectrum. The midrange and upper midrange is voiced by two custom spec balanced armature drivers, while the highs and ultra-highs are delivered by a high-performance twin supertweeter. It is this meticulous acoustic design that allows the dk-3001 pro to lead the pack for performance and value.
THE ONLY THING WE DIDN'T CHANGE WAS THE PRICE.
Everything has been re-thought and reconsidered in the PRO version of the DK-3001.
With perhaps more experience working with compact hybrid in-ear designs than just about all other manufacturers, DUNU pooled together this cumulative expertise to formulate a product that is both extremely high performance and cost-effective.
DATA-DRIVEN ERGONOMIC DESIGN
In 2015, we set out to design the most compact shell with no compromise to acoustic design with the DK-3001.
In 2018, we further improved its shape with the DK-4001, shrinking its size, drawing from a huge ear database to minimize chafing hotspots, and smoothing out its edges.
This new shape and design philosophy carries over to the DK-3001 PRO and represents a significant upgrade in comfort over the original DK-3001.
PRECISION MACHINED STAINLESS STEEL HOUSINGS
The advanced 316 stainless steel CNC process used in the DK-3001 has been further refined in this iteration of manufacture, allowing us to achieve an even more intricate level of fit and finish for the DK-3001 PRO.
It is now only marginally larger in size than the shells of the flagship DK-4001. In your ears, the difference can hardly be felt.
COMPLETELY RE-TUNED FOR APPROACHABILITY
Responding to extensive user feedback on the DK-3001, we sought to build on the success of our first DK series hybrid, and this meant reconfiguring the drivers.
The midrange is now voiced by not one, but two custom-spec balanced armature drivers with wholly independent tubing outputs, while the highs & ultra-highs are delivered by a twin supertweeter in the spout, for four BAs in total.
BERYLLIUM DIAPHRAGM DYNAMIC DRIVER
DUNU's engineers have been developing audio transducers for over 17 years. We pooled our veteran experience into developing an ultra-precise physical vapor deposition process to deposit Beryllium layer by layer.
Our exclusive dual-sided coating process enables us to control the thickness and grain structure of the deposition to fine tune the sound to our liking.
THE ONLY CABLE YOU NEED. THE ONLY CABLE YOU'LL WANT.
Unique to DUNU products are our patented Quick-Switch connectors, which allow a user to connect to all manner of portable audio interfaces with just the mere snap of a latch.
Purer than pure --- that's the overarching idea behind the LYRE cable on the DK-3001 PRO. We took an already high purity (greater than 99.9999% pure) OCC copper source and put it through a secondary fire refinement process before casting it into the final wire configuration.
The finished conductors are hand-braided in a round Litz braid to ensure flexibility and to minimize interference. The result is a staggeringly unadulterated sonic experience.
PATENTED CATCH-HOLD® MMCX
MMCX connectors have been widely adopted as one of the most popular connectors for removable earphone cables. We improved on this design further with our own patented catch-hold type connectors, lowering connection instability and pin breakages, and effectively prolonging the service life of MMCX connector interfaces. Catch-Hold® MMCX connectors are universally compatible with all standard spec MMCX seats.
CUSTOM SET OF SPINFIT TIPS
SpinFit, one of the premier silicone tip makers on the market, have customized a special set of tips for the DK-3001 PRO based around the CP360 and special silicone spacers.
JADE TINT LEATHER CASE
Bold and distinctive, the jade-inspired carrying case of the DK-3001 PRO is both protective and indulgent.
It provides plenty of space for additional storage of small devices, such as Bluetooth receivers, as well as a small elastic pocket designed to store your modular cable plugs.
