The DK-3001 is DUNU’s newest flagship earphone, representing the culmination of over two years of development and their latest crowning achievement in the premium earphone market. More than two decades ago, DUNU had its humble beginnings as an OEM/ODM manufacturer dating back to 1994. Over the years, DUNU have demonstrated the rare combination of high fidelity, robust construction, and incredible value in IEM (in-ear monitor) design for the price points they have targeted. As a result, DUNU’s product portfolio has caught the ears and attention of headphone enthusiasts and value seekers across the world. Notably, their TITAN series of earphones in particular has set the price-performance standard for $50-$150 price range, trading blows with earphones costing triple or more.


In this regard, the DK-3001’s demonstration of performance and value today is no exception and consistently true to its roots. Fit and finish that is tasteful, professional, comfortable and ergonomic thanks to the carefully polished and positioned components and the wide selection of provided tips for large, medium, small, and very small ear types. Accessories and box presentation is elegant and generous especially with the fold out packaging, balanced silver cable, and hard carrying case with padded interior and water resistant seal. This lavish level of premium treatment is what would normally be expected from earphones costing $1000 or more (such as the AKG K3001i).


Here is just one practical example of the test tracks that I normally queue up during evaluation sessions that revels in the DK-3001’s exceptional performance. The Lord of the Rings: The Fellowship of the Ring’s cinematic introduction is convincing, anchored and riveting. There is just the right amount of definition, presence, smoothness, and substance in Lady Galadriel’s voice to make for a crystalline allure that is fitting for the preface. The subsequent Battle of Dagorlad is rife with clanking, whooshing, growls and yells that are realistically sharp and bold, never straying towards either brashness or muffling. The sheer impact of the earthshattering shockwave that follows the iconic fall of the dark lord Sauron takes one’s breath away. Throughout the remainder of the film, DK-3001’s holds this command of dynamics and detail, rendering the jangling of metal and echo of environments, aloof and effortless in the heat of the battle and in the stillness of the epic journey.


In short, sound reproduction is dynamic, neutral, and detailed, making the DK-3001 the best universal in-ear monitor I have heard to date. Granted, there is a very slight upper treble shelving that is vaguely apparent which leads some to characterize them as warm or undetailed. For an individual like myself who generally gravitates towards bright, detailed headphones, I must disagree. I find this one minor deviation in the frequency response easily dismissible since the display of detail and clarity is simply breathtaking throughout.


Putting this into perspective, the Sennheiser HD 600 and Denon AH-D5000 are warmer and tubbier and the AKG K 701 has a far sharper cut off in the ultra-high frequencies (greater than 12 KHz). Hypothetically, if I were presented the choice of selecting either this or the Sennheiser HD 800 (which I had on extended loan just prior to my obtaining this review sample), I would pick the DK-3001 without question. Indeed, the DK-3001’s bass goes deeper and is more fleshed out, its midrange is more neutral and well-defined, and its treble transitions far more smoothly. Given its astounding value, I recommend the DUNU DK-3001 without reservation to any experienced audiophile looking for a competent and compelling earphone at its comparatively low price of $499.

DUNU is an inspiration in the world of earphones, a company having come out of relative obscurity and gained a name for itself with its value-packed, trend-setting IEMs, notably the TITAN 1, that compete with products costing hundreds more from manufacturers with decades in the industry. DUNU's product line is the sort of David and Goliath story that is the win-win that we all long for because it drives competition and lowers pricing, it forces the old guard to stay on their toes and up their game, and it makes for sweeping reviews and active discussions.
 
But between every battle, there are skirmishes, for every tock on the clock, there is a tick, and following every major breakthrough, there are subtle improvements. Along these lines, DUNU's TITAN 5 is a minor collection of tweaks to an already phenomenal product, the TITAN 1, making for an instant easily recommendable successor.
 
For starters, the same build quality you knew and loved about the original TITAN 1 is here to stay with added improvements that in no way detract from former glory. The same polished and utilitarian, rigid and rugged stainless steel housings now feature detactable cables making cable replacements and upgrades a snap.
 
The TITAN 5's spectular sound quality, also the hallmark of the TITAN 1, is both an upgrade and yet also a side-grade. While its familar-and-yet-improved sound eliminates and straightens out the very slight aberrations and edginess of its predecessor, the TITAN 5's sound signature is warmer and more musical. This is the IEM equivalent of the HD 650 coming from the HD 600.
 
In particular, you will notice smoother, less forced transitions from bass to midrange to treble resulting in a more natural, unified sound as a whole. Dynamics and detail stand out because, for example, the heft of a bassdrum kick is followed by its hum and rattle in its drum casing without jarring distortion and undue emphasis.
 
If I were to nitpick, the upper bass does bleed ever so slightly into the midrange. In head-to-head comparisons, even my Denon AH-D5000 that has a penchant for bass impact is less obtrusive--but the Denons are not bass monsters as some reviewers historically miscategorized them. The uppermost treble could do with a teeny bit extra shine and sparkle to make the projection of vocals more airy and the outlines of instruments more discernible. But the overall sound is so close to perfect that there is still excellent bite and definition for everyone but the most sizzle thirsting of treble heads and detail mongers.
 
Make no mistake: the TITAN 5 has not taken a step back but is TITANIC compared to the likes of competing products from Etymotic, Shure, and Ultimate Ear and many others. The TITAN 5 delivers the TITAN 1's performance and craftsmanship with much appreciated tweaks from top to bottom. If you are looking for the new king of the TITAN line, the TITAN 5 now bears the price-performance crown, punching well above its weight better than ever.
 
Thank you to DUNU, especially Vivian, for the opportunity to review this unrivaled product. Setbacks, including health and family struggles, tried my patience and likely yours as I worked to produce this review. I look forward to the bright and promising future of IEMs thanks to DUNU's untiring pursuit of immersive audio from fetching earphones.

I can say with a resounding "yes" that my hunch was right. Being the hard-core objectivist that I am, I frequently use InnerFidelity's datasheets as a gauge to determine whether or not a headphone is worth considering for purchase. A few weeks prior to acquiring the TITAN 1, I did just that. Based upon my observations of its measured performance, I hypothesized that the TITAN 1's actual performance would be legendary. Indeed, I have been far from disappointed in my decision. I can say without uncertainty that the DUNU TITAN 1 is up there with the best of ultra high-end headphones.
 
For many of you, the TITAN 1 can truly be your end-game or desert island earphone. Everything is right on target—or, simply, it just sounds so right. Singers, instruments, dialogue, ambience, sound effects, you name it, that inhabit the midrange have unadulterated realistic tonality. Pardon the cliché, but sound sounds just like it would in real life. Now, that is a tough feat to perform. The TITAN 1 matches the tonality of big dog headphones like the Sennheiser HD 800 and HiFiMAN HE-1000, both of which I have demoed thoroughly.
 
And oh, man, that clarity! Getting crystalline, sparkling clarity in a headphone is one thing. Shimmery cymbals, airy female vocals, brassy trumpets. But actually having a refined, grain-free, unfatiguing sort of clarity is the real balancing act. Strike the right balance and remove all anomalies, and you can see the sound and make out its texture with 20-20 auditory vision. Only the best of the best headphones can pull off this sonic feat and the TITAN 1 does exactly this without breaking a sweat.
 
The bass, too, is the kind that astounds. In an age where Beats are as bassy as McDonald's is greasy, the TITAN 1 is a breath of fresh air. In an instant, it can be delicate where the music calls for it. Yet unlike many audiophile headphones that are often too delicate, the TITAN 1 has a trick up its sleeve. It has also hard hitting authority to kingdom come. Yes, the lifelike punch of real music is all there. The bass materializes and disappears with pistonic precision. Put all these premium components (bass, midrange, and treble) of this sonic sandwich together, and you have an instant scrumptious serendipity of sonic splendor in your head.
 
So the TITAN 1 sounds out of this world, but the buck doesn't stop there. The build quality and accessories radiate the kind of craftmanship you normally see in $500-plus models: a Teflon-reinforced cable; a unique, especially patented rubber loop attached to the cable for coiling it with ease; a pristine buffed aluminum sleeve on the plug; two stunning, polished silver driver housings composed of space age metal; and even a durable black hard plastic case is included. No stone was left unturned in this pursuit for excellence. By visual inspection alone, this entire package in other brands would normally cost a bundle, because it certainly looks the part. Shockingly, it doesn't. That's the craziest thing about it.
 
The TITAN 1 is incredible regardless of its price, and receives my unfettered full recommendation. It is not the pipsqueak of a giant killer you might think it is; it is a full-fledged TITAN itself under the guise of a pauper's price tag. If you are earnestly shopping around for a pair of earphones that you likely never ever will have to upgrade from for only $115 (or $90 should you opt for the equivalent rebranded FiiO EX1), look no further. Snatch up the TITAN 1 while you can. You won't regret it!
