Dunu DK-3001 – The surprise: Relaxed and Romantic IEM
Dunu took on the challenge to create a multi-driver IEM at a very friendly price and they brought an awesome product to their fans! Their DK-3001 is the top-of-the-line IEM we see from them this year, and it
Dunu DK-3001 is the top-of-the-line IEM produced by the Chinese producer DUNU-Topsound.
Dunu is a large Chinese company that grew dear to audiophiles all around the world through their excellent communication with their fans, friendly support department and through high quality and well-priced products. Many audiophiles quote Dunu as the company who produces the
While Dunu are not as implied in organizing tours for their products, they have provided excellent service to their customers and are known to have an approach similar to FiiO, where they solve most of the problems that might appear quickly and with solutions that always advantage the customers.
Dunu doesn’t make many claims about the sonic abilities of their products, but they instead present the quality of the components used in their IEMs.
I have absolutely no affiliation with DUNU at this moment, I am not receiving any kind of incentive to sweeten things out or change my opinions about the product. My review will be as objective as it is humanly possible and it is a description of my general experience with DK-3001, every opinion expressed here is mine and I stand by it.
My name is George Dobrescu and I am the Director of the Seventh Heart Studios game studio. I work as one of the main programmers for the company, and I am the writer for Quantum Magica and Falsetto Memories projects. I spend eight – twelve hours a day working on a computer, writing and sometimes drawing. I also take care of administrative work which means that I require a portable setup so I’ll be testing the portability of iDSD as well.
Music is present all around me for a big part of that time as working with music is always more fun. With all the devices I own, I need great sound, comfort and ease of usage, not to mention that my listening volume ranges from “please stop that, it’s far too loud” to “I can’t even tell that you’re listening to music”.
My collection includes everything from Classical to Metal, from Rap to Pop, from Punk to Cabaret and absolutely everything in between. There are great artists from every type of music, and I’m one to collect their albums, and keep a tidy order for my files.
At Seventh Heart Studios, we all love music and this has had an impact on our games as we hold the music close to our hearts and we are committed to only use ogg -q10 as the encoding format for our music since it offers the best disk space to sound quality ratio, OGG -q10 being closest to audibly transparent when compared to FLAC encoding.
Personal philosophy: Music is more than a hobby or sound. Music is inspiration. Music is life. Music has meaning by itself, being the one thing that can define one’s life while shaping one’s imagination and creativity. Music can open doors to new plains and music can change one’s mood. Music can rest the mind better than days of sleep or can give one energy better than a thousand cups of coffee. Music can be anything we want it to be and the music we experience using professional audition tools is more but at the same time it is nothing more than our way of enhancing the emotion we get from music. Love is a concept too shallow, unable to encompass what music really means to a music lover.
I have actually never owned a Dunu IEM before DK-3001, and I have never owned a Multi Driver or a BA IEM before it. All previous reviews cherished DK-3001 as one of the best IEMs out there and it has been said to perform considerably above its price point, all of those things sparkling my interest in DK-3001. There is no DUNU official seller in Romania and I actually contacted Dunu directly, where I spoke with their lovely PR, Vivian, who has been extremely helpful answering even complex quandaries about multi BA-items and build-related questions. Dunu left a very good impression when it comes to their customer support and their passion for their job set light to the sparkle of my interest in hearing their TOTL IEM, DK-3001.
DK-3001 has been sent through DHL and it made me spend hours starring at the screen, waiting for another update about the package tracking. The packaged reached Romania fairly fast, under a few days, and the package arrived without any scratch.
It was a lonely day of Friday when the package arrived and I contacted and arranged to meet with the delivery driver somewhere outside the place where I live since it was simpler for us to do things that way. The sun was slowly fading under the clouds as a huge storm was getting close, but I was fairly optimistic that I’ll get DK-3001 before the rain starts to pour. I waited around ten minutes listening to a few beautiful musical compositions on iDSD BL + Meze 99 Classics, trying to keep my excitement contained. The delivery driver was very nice and handled me the package with care, but before I managed to get back and start writing about DK-3001, a curious bystander to know more about the audiophile hobby asked me a few questions about headphones, DACs and portable AMPs.
I managed to quickly get back in my room and started unpacking DK-3001, excited like a little kid who sees something for the first time. We got to admit, Dunu did an amazing job with the package, everything leaves a feeling of high quality and luxury, there are a ton of very useful extras in the package, along with a beautiful carry case.
Of course, with an item like DK-3001, the most important aspect of it was not the package, but the sound, so I carefully plugged them in iDSD BL and pressed play.
I decided to listen to DK-3001 while taking a walk outside since this helps me focus better on the music that is playing. The main choice I made was taking a lonely evening walk through the Politehnics park to admire the sunset while wearing an interesting IEM and experimenting their sound. Before leaving my home, I played a bit with the tips and found that Spinfits offer incredible comfort and isolation with DK-3001, so I put on one of the included pair of Spinfits and started walking.
The first song choice is an energetic and complex song as I want to see how the well-renowned BA drivers within DK-3001 will handle an overly complex song like Dance Gavin Dance – The Robot with Human Hair Part 4. I’m mesmerized with all the details they are able to show, but at the same time romanced by the polite and friendly presentation they have.
First things first, let’s get the packaging out of the way:
It looks like Dunu cares about offering a top experience to their customers, so they offer a rather impressive package with their DK-3001, the package including some rather useful extras. There is a wide selection of tips, two cables one of which is balanced, a glossy black carrying case, a shirt clip, an airplane adapter, and an adapter for 6.3mm outputs.
The first sight Dunu surprises their buyers with is a white rectangular box which sports an image of their DK-3001 IEMs, the information that DK-3001 is a 3BA + 1 Dynamic IEM, and, of course, the Hi-Res Audio sticker. There is not much information on the top and sides of the box, but there is an interesting headline on the bottom of the box. “Dunu – Delicate, Unique & Utmost”. To some degree, all three adjectives can be used to describe DK-3001 and their sound, and I actually like the slogan and want to put to test how much each of those attributes represent Dunu and DK-3001’s sound in general.
The back of the box includes quite a bit of information in both English and Chinese. The first interesting bit of information is that DK-3001 features an MMCX detachable cable and that it will be compatible with aftermarket upgrade cables. It is good to keep in mind that this allows the replacement of broken cables as well. The dynamic driver is made out of a “High molecular liquid crystal polymeric film”. All three BA drivers are made by Knowles and they promise to bring in an energetic sound along with a life-like experience. The housings of DK-3001 are made out of S316 stainless steel. For cable lovers, it seems that the included cables are 5N OCC cables with gold plated plugs.
It is interesting to have all this information nicely presented on the box, along with other useful information. The box is slightly similar to Apple packaging, but in Dunu’s case it includes a bit more information. The typical warranty for DK-3001 is one year, but you shouldn’t expect them to be breaking in many years of usage, especially considering the solid build quality, and the detachable cables.
After you remove the white cover, you will find a black cardboard box with a magnetic lock mechanism, with “Dunu” written on it.
Inside you can find DK-3001 seated in a foam cutout, along with the carrying box and all the accessories included with DK-3001.
This is what you’ll find within the box when purchasing DK-3001:
– Dunu DK-3001 IEMs
– A Single Ended Cable featuring a memory wire ear hook that goes around the ear and that helps fixing DK-3001 for better comfort.
– A Balanced Cable featuring the same design as the single ended one
– Dunu Branded Carrying Case. It is a glossy carrying case that looks similar to the ones made by Pelican and similar to the ones included by FiiO with their F5 IEMs.
– Comply Foam tips that fit DK-3001
– Spinfit Tips. Those proved to be much more useful than I imagined they’d be before trying them on.
– White and Gray tips for DK-3001, each with their own sonic signature, coming in three sizes.
– An airplane adapter
– A shirt clip
I like to see a large number of extras included with a IEM and DK-3001 is excellent in this aspect, including more accessories even than some high end IEMs. While some of them will serve very specific purposes, like the airplane adapter, some of the other accessories will be helpful for many users. The inclusion of a dedicated carrying box is also greatly appreciated and there is enough space within to include DK-3001 with a cable attached, spare tips and a little bag of silica dehumidifier. All in all, DK-3001 provides a fun unboxing experience along with a great package.
What you should look for when considering a IEM (In-Ear Monitor)
When purchasing an IEM, there are a few factors you should take into account to ensure that you’ll have the experience you wish for. Sooner or later, all those factors will come into play one way or another:
– Sound quality. This is, by far, the most important aspect of every purchase when you invest in high end audio products, and the sonic abilities along with the frequency response / sonic signature widely differs from IEM to IEM.
– Comfort / ergonomics. The fit and comfort are quite important, especially if you plan on using the same IEM for hours in a row, or in a live performance.
– Isolation. Every IEM will offer some degree of isolation, but there are both models that focus on ultra-isolation from the outside noise, while other models have other central focus points. DK-3001 isolates noise pretty well, especially if it is used with larger tips.
– Good Value.
– Interesting/Intriguing design. Every user will have a personal preference and taste for what an “interesting design” is, but it is generally recommended to pick a IEM which you consider to be aesthetically pleasing, or in simpler words, good looking.
– Drive-Factor: How easy it is to drive and how prone to hissing it is, since certain IEMs and headphones will require special sources to offer the best performance.
– Accessories included. It is better to have a large selection of tips and accessories included with a IEM.
– Build Quality and Warranty. While it is good to have a solid warranty included with Every IEM, having a solid build quality is better.
